V700 Modbus Master Slave TCP

[Automation of Things]

Hello,

I am trying to get Modbus TCP connection between to V700 PLC but cant get the the Master "TCP Connection to Establish" ..

I have copied the Demo example with in the software.

V700_Modbu_TCP Slave

V700_Modbus_TCP_Master

on Visilogic  V9.8.91

I have  two V700 Units and a  PC connected to a unmanaged Switch using stand Cat5 Patch leads.

PC IP: 10.1.90.189             V700 Master  IP: 10.1.90.190                   V700 Slave  IP: 10.1.90.191

I can ping both V700 from PC.

On connect (From HMI) the V700 ETH Card Read = Status #22 = 19  (wont change to 23)

I have left all the default parameter from the Demo programs.

Looking for help to see if anyone has had the Demo's working / communicating..

And what tests I can preform to narrow down my issue with the connection between the two V700 PLC's

Thanks in advance

Regards Brian

A quick look and you have different references to gateways, you don't have a socket init in the slave.

If you can Ping both PLCs from your PC, then the next course of action is to go through all the initialization and configuration blocks with a very careful eye. There are LOTS of entries and one wrong number will bring the whole thing down.
