Hello All:  
I am a new user of ignition software. We develop control systems for pharmaceutical industries. We are currently working on a project which includes PLC, HMI and other Modbus TCP/IP or RS485 device. I know we can communicate with PLC and HMI through ignition software. But, there is any way we can communicate with other devices using Modbus TCP/IP?

Please let me know,  
Thanks in advance,  
Shwetha.

Yes - There is an included Modbus Driver.
