DCE TCP Modbus module to PME communication issue

This question was originally posted on DCIM Support by Kaloyan Georgiev on 2016-08-08


Hello,

I have installed PME 8.1 and DCE 7.3.1 with Modbus TCP module.

When I try to read some data in PME from DCE, I get an "Invalid data address" modbus error. It is not a timeout, so the communication is working.

Can you help me connecting the two softwares together?`

The information about the error is in the attached pictures.

Modbus TCP output only able to start from register 31000 as the option when you generate the register list "Please choose a register value between 31000 and 39999" So you may need to read as Input register, @31000, and in Modbus address, the register address will be 331000

Hello, I tried and I have a success. The problem was that instead of address 31020 i should use 331021. Now everything is OK. Thank you for the support! Regards, Kaloyan
