Character at offset 92 in datablock 945 (interestingly this came across as the ASCII code for the character, which I then had to use a script to convert into an actual character):.Double word at offset 42 in datablock 947:.The following are some examples I found in this project that illustrate this format: With a few adjustments, the following format yielded correct addresses for reading the OPC tags within Ignition: After experimenting, I eventually discovered that syntax was the problem. If I couldn’t find the solution online, then I would find the solution myself-one of DMC’s core values is “Make Things Happen,” after all.
#Siemens simatic s7 300 plc article no. how to
So, I scoured the internet for an explanation of why this occurred. All of the forums I read through, however, pointed to the same Ignition documentation I mentioned earlier for how to correctly address these tags. This error was strange considering I had other tags already reading properly over this OPC server.
I confirmed my OPC connection was good, then I configured my tags as described in the documentation.and I got a configuration error. Since I know Ignition’s documentation is usually quite stellar, I consulted their guide to help configure my OPC tags. These tags were communicated using an intermediate Siemens SIMATIC NET OPC Server. Recently, I needed to access tags on a Siemens S7-300 PLC in Ignition 7.9 for one of my projects.
