I'm working on a project and replaced a siemens plc with an H2 Do-More PLC and a SERIO-4. It's a gantry style drilling machine with 3 servo axis utilizing Simatic V90 servos and an INVT G100 VFD.
Hardware
I'm having a problem reading and writing to the drives, all set to even parity checks, baud rate of 38400, UI set according to the order, and tested with and without terminating resistors.
Serio-4 C: RTU Master
Questions:
G100 VFD:
Any feedback or advice on how to go through and check the parameters and make adjustments would be greatly appreciated.
Thanks

Questions:
V90 Servos:
1) RS485 monitoring time, default is 0ms and curious as to what the proper method is to set it given 4 slave items.
2) Modbus addressing: Assuming the ex 40100 addresses are dec and not hex. Offset address 100 for instance for the MWX MRX?
2) Modbus addressing: Assuming the ex 40100 addresses are dec and not hex. Offset address 100 for instance for the MWX MRX?
G100 VFD:
1) Addressing documentation is ex 2001 hex, converting to dec is 8193, so the MWX and MRX offset addresses are?
Any feedback or advice on how to go through and check the parameters and make adjustments would be greatly appreciated.
Thanks
