This is my first time using Ignition SQLBridge with siemens typically I use AB drivers. I setup my devices, they show connected I am adding a tag just for testing and I am getting a results of bad. I setup the tag
OPC Server as Ignition OPC UA Server and the OPC Item Path as [PLC10]DB4030.DBD16 where PLC10 is my device name.
Am I doing something wrong. This application I am upgrading from FSQL which I used Kepware. Should I get the OPC Comms module and Kepware or should I feel ok that the Siemens OPC UA drivers will work.
I am still working on this project since I am converting a FSQL with 1059 groups that was using Kepware to Ignition SQLBridge using the native driver after pturmel help I have converted a lot of the groups but I seems to have problems with converting this address to one supported by the Ignition UA drivers DB25.KT20 I have try [PLC52]DB25,T20 but I get an error " [null, Bad_Stale, Wed Aug 28 00:14:20 EDT 2019 (1566965660122)"
Are you trying to read a S5Time? This datatype is not supported by Ignitions Siemens driver. There is a workaround here, but if you also have to connect to more modern Siemens plcs, an external OPC-UA server might be a better solution.
You don’t need access to the Plc, the conversion of the S5Time type can be done in an expression in Ignition. You can access the data with datatype ‘word’ even when it’s defined as ‘KT’ in the plc.
I have good experiences with the server from Tani (https://www.tanindustrie.de/en/Opc.php) especially for S7-1500 with symbolic access. Due to a bug in that server it does not work with Ignition versions > 8.0.4 rc, but I hope this will be fixed soon.
