Post by dnordenberg on BOOL variable in OPC UA and modbus simultaneously ^{CODESYS Forge talk (Post)}
How can I have an BOOL variable that is read/write in both modbus TCP server and from OPC UA at the same time? Variables with %MX.n %QX.n addressing which is used for BOOL/coils in modbus server is not allowed in OPC UA symbol list on Schneider M251 controllers. I have already asked on Schneiders forum but there are not a lot of codesys experts over there :( So OPC symbols can't have a address and the modbus TCP server needs a address. So how should I do it then? It seems like an impossible combination. Since I want read/write access from both ways I can't just simply make a second variable and assign it the value of another since it would be a one way assignment. I also tried using VAR_CONFIG which then makes the address syntax %Q or %M in my main variable list and that fools OPC UA Symbol Configuration to allow it and then I add the complete %MX.n address of it in the VAR_CONFIG list. This semi works, I can toggle the BOOL from modbus but the OPC UA symbol seems to be read only. It displays symbol status but nothing happens when I toogle it. I think I need another way to have the variables and symbols pointing to the same bits in memory... My plan B is to write a BOOL array compare FB that saves a history bit from previous cycle and if that does not match current status at next cycle for either the OPC symbol or the modbus variable then it copies the new status over to the other. Maybe ugly but it's like my last alternative. Kind regards David

Post by astrum on SPS Shell Commands im Projekt einbinden ^{CODESYS Forge talk (Post)}
Hallo zusammen, gebe es den die Möglichkeit SPS Shell Commands wie "Cert-Import" ins Programm einzubinden? ich habe versucht meine OPC UA Zertifikate über die sysFile Bibliothek vom Quarantäne zu vertrauenswürdig zu kopieren, was auch geklappt hat, aber das Zertifikat wird erst erkannt wenn ich die Steuerung neu starte. Ich habe mitbekommen das, dass mit der cmpPlcShell Bibliothek funktionieren soll, leider blicke ich bei der Beschreibung nicht durch. Hat da jemand eine Idee ?
