Hello everyone! I am currently working with a Simatic SM374 (374-sxh01-0aa0) sim module in TIA Portal v.18. Despite not being able to locate this specific module in my list of hardware devices, I found information on the Siemens website suggesting that I can choose a similar module instead. However, I am facing a challenge as I cannot find any documentation for this module, and I am unsure how to address it in my PLC program. If anyone can point me towards any available documentation for this module, I would greatly appreciate it. Alternatively, if you have any insights on how to set up addressing for this module in my project, please feel free to share. Thank you for your help.
The simulator module's functionality can vary based on the rotary switch located at the front, offering options such as 16 inputs, 16 outputs, or 8 inputs and 8 outputs. To clarify, these specific configurations are not currently listed in the catalog.
In reference to the simulator module, JRW noted that its functionality can vary depending on the rotary switch located on the front panel. It can function as a 16-input, 16-output, or 8-input/8-output module. While this information may not be found in the catalog, it is still available for installation. However, there seems to be a lack of guidance on how to create an image table for the I/O and address each individual bit. Unfortunately, documentation on this specific topic appears to be elusive.
When selecting a 16-point input card with the switch set at 16, choose any compatible 16-point input card. For instance, consider using a 24VDC 16-point card, where your IB bytes 0 and 1 correspond to the first input (e.g. i0.0). Create a VAST (Variable Analysis and Simulation Tool) table and conduct experiments to analyze the data effectively.
Have you recently installed the most up-to-date hardware support package (HSP)?

Hi there! I've also navigated similar task in the past with another module, and sometimes the exact version might not be listed, but you might be able to work with a model that's a close match. In TIA Portal, addressing is generally fairly flexible - you can often use Symbols instead of direct addressing which makes your program much easier to understand, maintain, and troubleshoot. However, I strongly recommend to get in touch with Siemens official tech support for the specifics on the SM374 module as they should provide the most accurate guidance. Online forums and communities for Siemens PLC users, like PLCS.net, may also host some discussions that you would find useful in dialling down into specifics. Hope this helps!
Hi there! I've encountered a similar issue in the past. Sometimes, the specific module may not be listed due to differences in regional versions or updates. Trying a similar module might work, but it could also create differences in your PLC programming, so be cautious. Regarding the documentation, you can try reaching out to Siemens customer support directly. They're usually very helpful and can provide you with detailed information. As for addressing, it largely depends on the nature of your project and other hardware you've in the setup. Generally, it's vital to ensure correct IO addressing to avoid issues. You may find PLC programming guides on Siemens website helpful enough to set it up. Hope this helps!
Hi there! I've encountered similar issues in the past. Although I haven't worked specifically with Simatic SM374, in my experience, similar modules typically behave in the same way. My recommendation is to go with the substitute module that Siemens suggested. As for addressing, each PLC has its own addressing scheme, so, if you can find it, a manual for the PLC might be your best bet. Also, don't forget to check the TIA Portal's built-in help system if you haven't already, as Siemens often has quite comprehensive resources there. Hope this helps you out!
