Hello all,
I have tried to communicate my PLC S7 315-2 DP as Client with Open Modbus to Delta V, I have followed the procedure to register the PLC with the Siemens license according to the manuals successfully, but still not getting communication
Previously I have an HMI connected to a pasive read write TCP connections 01 and 02 and this is working correctly, and I created a third connection for the Modbus device, and the local port 202,
I have a Vat table to monitor the parameters, and I can see that when I enable the ENQ_ENR and the WRITE_READ bits, I start getting error and the status I observe is W#16#8183,
I used a Omni MBT Modbus Tester, but I was not able to receive or send,or even see the PLC,
The Hardware I'm using is: PLC 315-2 DP
343-1 Ethernet card connected with port No1, IP address 10.168.129.115, connected to a Ethernet Switch
HMI Proface 3500 series, Ethernet Connetion, IP address 10.168.129.18
The Modbus Server IP 10.168.129.104 with remorte port 502.
, is there anybody who could give me some advice on how to trace ot troubleshoot the system.
My questions should be, is there a proper order to create the communication connection?, should I need to install another independent 343-1 card in my system in order to have a different segment for Modbus or how should I define the hardware in order to get a Modbus Signal thru the Ethernet,
BR
