If you are upgrading from S7-300 to S7-1500, you may be wondering what the equivalent replacement is for the FM350-1 encoder card. While there are several counter cards available for encoder functionality, some may not clearly indicate how to use the Anot and Bnot signals.
TM PosInput uses the symbols -A/-B instead of Anot or A bar. While the terminology may have changed, the concept remains consistent.
Great! It seems like this option could be a suitable solution.
In the upgrade from S7-300 to S7-1500, there isn't a directly corresponding replacement for the FM350-1 encoder card, unfortunately. However, you can consider options like the TM Count 1x24V card that can work with the Anot and Bnot signals, although it may not be as straightforward. Siemens provides a comprehensive guide and you might also need to do a bit of programming to get it functioning as per your requirements. By the way, it's a good idea to also reach out to Siemens customer support—they're usually very helpful with these types of queries.
In shifting from S7-300 to S7-1500, the TM PosInput module would be a suitable replacement for the FM350-1 encoder card. It supports comparable functionalities, although it utilizes the Configuring Technology Objects in TIA Portal instead of Anot and Bnot signals. You might face a learning curve, but there's plenty of documentation and community support to help you overcome it.
You're totally spot-on about the confusion in upgrading from S7-300 to S7-1500. With the S7-1500 series, the 6ES7531-7KF00-0AB0 module is often recommended as it offers High Speed Counter (HSC) functionality much like the FM350-1. Unfortunately, it doesn't natively support Anot and Bnot signals. However, it's possible to work around this by employing a small change in the wiring configuration together with some changes within your PLC code to correctly interpret these signals. Remember though, managing this potentially nuanced process sometimes is a breeze with the guidance of an experienced automation engineer.
