Posted 2 Feb 2017 I have CPU IC200CPU001 and AI input module IC200ALG620 with termoresist Pt1000 sensor. How can I get diagnostic information from that module so break, overflow etc... Share this post Link to post Share on other sites
Posted 2 Feb 2017 In hardware configuration you can set up low and high alarm levels. The alarms appear in the PLC's IO Fault table. Since the procedure to read the fault tables from ladder logic is somewhat awkward, it is probably easier to add ladder logic to detect low and high levels of your choice and set bits to indicate alarm conditions.
