Which flavor of Kepserver OPC server are you using?

I made this in the plc:

The PLC appears to be configured correctly, although the name is a little long.  What you've done is set the PLC up as a Modbus TCP slave.

 

1.  What is the IP address you assigned?

2.  What are parameters you used in the SOCK INIT block for Socket two?

3.  What have you done with KepServer so far, and what errors are you getting?

4.  Where did you get your copy of KepServer?

I did a little more digging on KepServer - 

 

Here's their Help on configuring it for Modbus TCP:

From the Unitronics side, read the Help on Modbus Slave Addressing - under the Search tab search for "Modbus" and choose topic 2 - "Slave Address Tables".  Click on the link that says "Enhanced Vision Series" to show you what Modbus addresses correspond to which Unitronics addresses.

Hello!

 

I made a screensoot from my settings:

 

I wanted to try to read an input from the plc.

Kepserver error message: Device 'Channel1.2000926907' is not responding.

Your last dialog box for tag "prb" - what is the address in the PLC you are trying to read?

I tried to read the I2 input from the PLC.

[Joe Tauser]

Look at Visilogic Help topic "Modbus Slave" and then "slave addressing" for the Slave Addresses of Enhanced Vision Controllers.  It shows the "I" coils starting at address 6000h, so I2 would be 6002h.  This translates to 24578 decimal.

 

Try putting this address into the tag definition for prb and see what happens.
