Hello, I am trying to communicate IGNITION 8.1 with Siemens s7-315 2 PN DP PLC without success , i used Step7 5.6 (not TIA) to develop the program. the PLC ref: "315-2EH14-0AB0" Version 3.2 the ip adresse of PLC: 192.168.1.183 the name of PLC: AS the ip adresse of ignition station: 192.168.1.187 in ignition i set in device connections the same parameters in the plc project and also in port (102) and slot number (2) But PLC remains disconnected. the Plc ping is ok, i also use the telnet (telnet 192.168.1.183 102) without error. Please advise on how to get rid of this. Is there any specific setting in Ignition for S7-300 plc communication? ---

Hi [Abdessamad\_Bouselham](https://forum.inductiveautomation.com/u/Abdessamad_Bouselham), I would suggest opening a ticket with the Support department. They would be better suited to help with this issue.
