[Linking Red Lion G310 to V350 Communications Issue]

Dear Forum,

I have an existing RedLion G310 HMI display that is currently connected to a V120. Communication is via Modbus RTU.

I am in the process of replacing the V120 with a V350 so I can expand my Ladder program.

Unfortunately for me the Mosbus Slave addressing in the V350 is now different to the standard vision and is Hex based. This now means if I want to read say, ML's I have to enter a very high Modbus address, which exceeds the "Max enrty value" of 465535 in the Redlion HMI. Which gives me a problem.

I do however have another protocol option. The newer version of Crimson software (Redlion HMI programming environment) support "Unitronics" in the form of:

Unitronics PCOM ASCII Master (serial)

or

Unitronics PCOM ASCII TCP/IP Master

My V350 has an ethernet port installed and I have tried to communicate using the Unitronics supported TCP/IP protocol rather than Modbus TCP/IP...... but without any sucess!

My settings in the HMI for communiaction to V350, are as follows:

V350 IP address: 192.168.100.1

Port: 20256

Unit number: 1

Link type: use dedicated socket

ICMP ping: disabled

connection timeout: 5000ms

transaction timeout: 2500ms

Is there anything I need to set up in the V350 apart from the IP address: Any special FB's? do I need to set the same port number (20256) somewhere in the V350? different port number?

Any help or advise would be greatly appriciated.

Hello Hal9000

I have a problem, I want to communicate the unitronics V350 with a red lion device, in particular the G07 through the communication protocol MODBUS TCP / IP. I see you had a similar problem.

We have already reviewed the parameters you mentioned and they are the same.

 Could you help me with some information please?

Thank you so much!
