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.
Justin
