I think if you configure the new OPC server (V15) with the most up to date version that Simatic Manager has, it works.
cfg file in TIA portailĪny Idea how to solve this problem, i need an OPC server V15 communicate with 2 PLC running on Simatic Step 7 V5.5 I tried to export the blocks(.AWL) and the hardware configs (.cfg) then import it in TIA portail V15, it generates a lot of error for the FCs that have been built in STL, and i could not import the hard ware configs from the.When I try to migrate the project from S7 to V15 it comes with alot of errors.The PLCs are ruuning under step 7 program V5.5 so i can not add OPC V15 in the HW configs.I want to upgrade the PC station, so i installed SIMATIC net V15 to be compatible with Windows Server 2012 R2 (my new station). I have a system of 2 PLCs Siemens CPU 315 - 2PN/DP (with a program Simatic S7 V5.5) and PC station runs Siemens OPC server Simatic net V7 ,and they are connected over Ethernet.
