Ignition SCADA Modbus to 350

[Rafe]

Hi I am trying to connect a 350 PLC with Inductive Automation's Ignition SCADA using Ignition's Modbus TCP driver. 

 

The PLC program image is attached. 

 

 

I do get a connection established in the Ignition software to the PLC but I can't read any tags. 

 

The following are all the settings I have in the Ignition SCADA

 

 

 

 

 

I have tried Ignition's Modbus TCP, Ignition's Modbus RTU over TCP, Kepware's Modbus TCP driver all to no avail. 

 

I already have 2 other PLCs connected to the SCADA system via modbus TCP so I know that the Ignition's Modbus Drivers work. 

PLC program is also attached.

Please advise. 

Kind Regards

Rafe

Rafe,

Test MODBUS TCP communication first by well known MODBUS Client.

You can use Chipkin CAS Modbus Scanner.

Check Slave Addressing in VisiLogic Help.

If this test pass - test SCADA.

Set the SB168 power up value to 1, like the program check is telling you to do.  This may or may not help in this particular instance, but needs to be done to ensure continuity of comms.

I know from experience that the Ignition software will work with a V1210 using MODBUS TCP. I don't see anything in your posts where you show the register addresses you're trying to read.

Got it going using the following information

For Holding Registers, add 40,001 to the MI address in VisiLogic. In other words, if you're trying to read MI 123, the Holding Register read address in Ignition should be 40124.
