  • View Sitelink Data Usage

    I just set up a Sitelink Wifi version. I am very impressed. It was easier than the EWON or Tosibox and seems to have features that combine the best of both of those major competitors. It took me a bit to get the HMI webpage to be viewable from the Android app, but once the service and default landing path were properly entered, all is working well. The only thing I have not tested is outgoing emails from the HMI but I think if I just enable internet access from the LAN under the firewall options it will work as long as the ISP doesn't block them. I will move the unit to the customer site in a few weeks and try it before changing that option, but I am off my intended subject.

    The thing I have not yet found that I am sure is there somewhere is usage statistics. Where can I see how much of my free 5gb has been used?

    My recent experience has been less favorable. My bad experience starts with email from the Cmore EA9-T7CL. Email will work fine if all IP addresses are set to DHCP. However you cannot access your device over the VPN router using DHCP. You must have a static IP address for VPN access. Then the DNS settings will not allow the Cmore to find a DNS server so that you can use an email address. I had to set the email server address to the static IP Address of the server name. In other words smtp.gmail.com will not work because the DNS will not resolve the name. The only way it worked for me was to use the Static IP Address of the email server. This was true when using a wireless hotspot and the Stride Sitelink Router.

    Now the Router, most of the problem there is AT&T / Cisco Jasper, but they are making changes as I type. Unlike OkiePC my Sitelink Router is a 4G cellular unit. My problem started with the SIM card not being activated when I received it. The only Customer support that you will find for the IoTs product is at this email address AT&T Marketplace Customer Service <starterkit-support@iotservices.att-mail.com>. They have been helpful but not always quick to respond. Once my SIM was activated I purchased a 1gb /month plan, however they automatically signed me up for a 50mb per month which is not enough.
    Apparently the Router alone uses a minimum of 120mb/month just to be connected to the cellular network. This I had to prove by disconnecting my Click PLC and Cmore Panels for the device and letting the router run for a week during which time it generated 200 mb of data usage. This is too expensive to operate this way.

    You do have to allow Internet Access in the Sitelink configuration web site to be able to send email through the device. Be warned this opens up a full Internet connection. I found this out the hard way. Remember my previous discussion about DHCP and Email. I had configured the SiteLink Router to hand out only 4 DHCP addresses while attempting to get the Cmore email to work using DHCP. When it did not work I failed to shut down the DHCP server in the SiteLink router. A week later I was performing Windows 7 updates on two computers that had not been used in a while. When I turned them on they picked up IP addresses from the router and connected to Microsoft's Servers through the router. 1.8GB later and over $400 in data usage I found out that Internet Access in the Sitelink is exactly that. I was under the impression that the router was restricted to only certain protocols making it safe. It is completely open. I did not know that this had occurred until I checked my email and found multiple charges from AT&T for data overage.

    Of course all of this will be avoided if you have internet access available to use the non cellular router, but if you are like me and need a cellular connection be prepared for a battle. I have only had this system operating for one month and today the Router is completely powered down to avoid any more charges.

    With the cellular product and AT&Ts SIM Control Center account management platform you can see everything going on with your SIM cards relating to data usage. I have not investigated the data usage at the Stride Sitelink page as yet.

      I have found that most industrial devices cannot send authenticated emails and very few email services will work without authentication. We use AuthSMTP to get around the problem. I think I pay them about 50 bucks a year to send 2000 messages per month. I have several customers using AuthSMTP on that one account. I did have to get AuthSMTP to keep my account on a fixed IP at their end which cost nothing extra except an email to their tech support. They replied with the IP address I should use in my hardware where you would normally specify a mail server by name. Also you can't use a gmail address as the authorized sender in the AuthSMTP setup, but we have a domain (through google/gmail no less) so we just added a generically named user to our domain to get around that issue. Check out AuthSMTP.com

      I have not had problems accessing the Red Lion HMI web page from a PC or phone but from my work phone (Android Samsung S7 on AT&T) I have to have solid cell signal for the page to load. My personal phone (Android Samsung S7 on Verizon) getting to the HMI is quick and error free even with one bar. I have three other VPN services installed on my work phone along with a handful of other apps including security and ad blockers that might be causing a conflict.

      The EWON we have at one customer was almost as easy to set up but it is not as responsive when using the web based VPN. I find that entering a setpoint on their Red Lion Graphite HMI takes about 3 seconds per button press. Some of that lag might be due to the customer's ISP which is a wireless radio mounted on a pump building about 3 miles from civilization on a dirt road.

      I do think that the Sitelink Android app needs some spit and polish. Sometimes I click on the HMI link and nothing happens. Sometimes I click on the Device and a page slides into view from the right then disappears. Click it again and the list of "services" slides up from the bottom. The PC based VPN client seems to be more well refined, although I have only spent a couple of hours in total using it, I have pretty high expectations. The proof will come when I stick this thing in a water plant 200 miles from the office and the operator calls me to get online and help him through an issue or make a program edit or something.

      I'm hopeful that A/D will spend the effort to make improvements and bug fixes like they have with most all their other recent new products.

        Is anyone having issues with their Sitelink other than what has been talked about above?

        I'm seeing huge delays in transfer times of programs. IE, update a C-More display is taking 2-3 minutes, locally it would be 30 seconds. The local internet connection is 1g fiber (900/870 typical speeds), remote is 100 down / 5 up (so effectively I have a 100mbps link between the two locations).

        The biggest issue I'm having is similar to above, but 90% of the time if I do a stop mode transfer to a PxK, the transfer fails. Massively compounding the issue, when a stop mode transfer fails, it loses the static IP I had set in the program and it goes out and grabs an IP from DHCP. Great that it has an IP, horrible that I have no idea what IP it is to reconnect to it. Even runtime transfers take ~60 seconds.

          Hello Okie,

          I have not had any problem with email being authenticated. I had set it up on my personal Verizon account using my personal profile and servers. It worked fine. When I set up the Gmail account I had to change a security setting in account settings to allow less secure apps to have access and the smtp authentication works. I am however only using one account, and one Cmore at this time. I have not attempted any phone apps to view the system over VPN but I have viewed the web server via my home PC and it worked well with hardly any delay.

          My Email problems have all been with DNS. I have upgraded to the latest firmware and it made no difference in this area. I have two Cmores and both of the operate the same. See attached image of email set up. It will only work with a static email server address.

          for Brandon I have not attempted to load any program remotely so I can not comment on delay issues.

            @tpeery,
            When setting up the Cmore to a static IP, are you entering your Sitelinks LAN IP as the gateway? Or are you leaving it at 0.0.0.0?​​​​​​

              PLCnut, Yes, before using the SiteLink Router I have used a Verizon HotSpot. The Default Gateway has been set properly in both situations and with the same result. The system works flawlessly with DHCP. However once you change all settings to static it will not resolve the name of any email server. So the email server has to be set to a static IP address.

                I am not having any problems uploading and downloading to a Micrologix 1400 and Red Lion G15 using the VPN. It took 51 seconds to upload all programs and data from the ML1400. It took 20 seconds to extract the image from the G15 using Crimson 3.0. I just did this from a hotel room in Denver reaching across the web to our office in Oklahoma.

                My work phone will no longer connect at all to the HMI webpage. My personal (Verizon) phone works flawlessly even with a poor cell signal. Both phones are Samsung Galaxy S7, the work phone is the "Active" ruggedized variant with AT&T as the provider.

                  Interesting.

                  I guess I'm an isolated incident? I would blame it on the P2K PLC at the other end as they've had network connectivity issues in the last revision of the software, but my C-More panels are taking and absurdly long time to transfer as well. What takes 20 seconds when I'm local to the panel or PLC is taking 2-3 minutes. As I'm remotely programming a PLC right now while another guy is on site, 1 minute runtime transfers are getting incredibly annoying.

                  I did just realize that I was on firmware 3.1 (current is 3.5). It's in no way obvious that there is a firmware update if you do it from a PC. It wasn't until I logged in with my Galaxy Note 8 that I saw the firmware update notification. I updated, no change in performance.

                  Nail in the coffin was pounded in tonight. I assumed that since there is an iOS and Android app, that would allow remote VPN so I can at least remotely do troubleshooting via C-More. I was completely unaware until I read the section in the manual that you cannot establish VPN connections via iOS or Android.

                  Back to eWon Cosy's I guess. I REALLY wanted to love this VPN. The built in wifi AP is fantastic and something that I have begging eWon for so that I don't have to hang an external AP off of it (I buy the wifi model but never use the wifi for internet connection). The speed issues and lack of Android VPN connectivity are deal breakers for me.

                    A/D Tech support has contacted me about my concerns and let me know that the usage data will soon be available. They also got an understanding about my confusion with the Android application. And for my work phone not working right, we have replicated the issue with my boss' phone. It seems that when we are connected to our shop wifi, the connection works fine. This is the same wifi that the Sitelink uses for internet access. When I turn off wifi on my work phone, it can't connect. Not sure under the hood why this is a problem, but it has something to do with the same wifi information being present in the Sitelink and our phones or the fact that my phone is "remembering" a path that I later make unavailable. In any case, we have some things for them to chase down.

                    As for Brandon not being able to use it as a VPN connection, I think what the manual is saying is that it is not a direct VPN connection, but will be cloud based when using a phone. I would expect that you can still use a phone based VNC viewer through the Sitelink app to do what you want.

                      It very much sounds like the Sitelink is configured to pass traffic to the corporate network via port forwarding (this is an option in the config of each router). So even through you're connected to the shop wifi, it still passes traffic through behind the VPN. This would be a completely expected and normal scenario with any VPN configured as such.

                      As for Brandon not being able to use it as a VPN connection, I think what the manual is saying is that it is not a direct VPN connection, but will be cloud based when using a phone.

                      From what I can tell, there is no way to connect Android or iOS to the VPN if you're off of the local network. There is no cloud-based connection (unless I'm completely blind). You can edit config and such from the mobile site, but there is no way to connect. You can see that the VPN is "Online" but you're not connected to it, you're connected to AD / Sitelink's management portal that has no connection to the router.

                        I too just ran into the issue with using a FQDN for the email server. sub5.mail.dreamhost.com doesn't fly, but the resolved IP does. Cosy has no problem with the original configuration. I'm tempted to use 8.8.8.8 in the C-More for a DNS server , but at this point I'm scared to make such a config change since I no longer have physical access to the panel.

                          I do not have the options enabled in my device firewall for Lan > Wan or Wan > Lan.

                          I can connect to the web browser in my HMI from anywhere with my personal Android phone which uses Verizon as the provider. So the app does get through the VPN, even though there is no "connect" button, it does work. Yesterday when I was talking with tech support, I think he said that the phone app is always connected when running, so there is no connect button like with the PC based VPN app.

                          EDIT: I have been corrected in an email with tech support: "I saw your last post on the forum and wanted to clarify. The connection from the phone/SiteLink app to the cloud is encrypted through HTTPS at all times, but it is not connected by VPN. VPN is currently not supported on the mobile devices. The reason Brandon and others want mobile VPN is because it allows them to connect by the C-more mobile app and control C-more devices remotely from their phone. You are able to securely connect and control through the SiteLink app to the webserver for the Red Lion HMI. The C-more webserver only allows viewing data, not control."

                          Here is a screenshot from my cellphone which is not connected to the shop wifi:

                            I got some info back from engineering today.

                            I was correct that there is simply no way to directly connect to the VPN via mobile at the current time. In Okie's instance, a HTTP service was added to the Sitelink config pointing towards the RedLion's IP. The Redlion has an internal web server that allows you to access that data. It's basically a port forward through a secure tunnel. Unfortunately for C-More users, a HTTP port forward doesn't do anything beneficial for us (or at least, me). We need a direct connection to be able to use the C-More mobile app and at the moment, that is a huge limitation of the Sitelink platform that Cosy does not have as a limitation.

                              Just an FYI about emails. For my HMI to send emails, In my Sitelink device I had to enable the firewall option for internet access LAN -> WAN. Without that enabled, the HMI could not ping the email server or succeed in sending them. With it enabled, my outgoing emails work. This should not be a problem for my end users, but it might be beneficial if the Sitelink allowed more specific access to be granted like only allowing SMTP protocol or certain ports to be opened up. I can't imagine someone opening the PLC panel and plugging in to watch Netflix from the little water plant I am putting this in, but somewhere someday somefool will think of it.
