Hi, I am using a S7-1200 CPU (6ES7 214-1AG40-0XB0) to communicate with 14 LOGO PLC for data exchange via Modbus TCP/IP. I have configured all LOGO PLC as MODBUS server and S7-1200 as client for all LOGO PLC. When I tried to exchange data between S7-1200 PLC and 12 LOGO PLC everything works perfect, but when I connect 13th and 14th PLC these two PLC does not exchange data with S7-1200, rest 12 LOGO PLC works fine. After disconnecting any two of the previous connected LOGO PLC(out of 12), then the 13th and 14th one's communicate and exchange data properly. **I have used seperate "MB_Client" block for each LOGO PLC. **I am getting "8087" error status at "MB_Client" block when S7-1200 read data from 13th and 14th LOGO PLC. I mean to say S7-1200 read data from these two LOGO PLC only once before getting the error. Thanks in advance. ------------------------------------------------------------------------------------------ |
