text: <s>[INST] Issue with an A-B PowerFlex 753 Summary: Event DigIn Cfg B, DI Run and DI Fwd Reverse at the same time shouldn't be an issueHi, I installed a PF 753 (20F-11ND052AA0NNNNN) Firmware: v2.007.37 with a 24V DC 22-Series I/O Module (20-750-2262C-2R) on slot 4 Configured: DI Stop on Port 0: Dig In Sts.Digital In 1 DI Fwd Reverse on Port 4: Dig In Sts.Input 1 and DI Run on Port 4: Dig In Sts.Input 0 I usually configure inputs this way: two-wire RUN (and normal STOP, ramp or coast), one DI for FWD/REV (if required) and one STOP which I utilize for fast stop (current injection or some other means) In this case I am getting message DigIn Cfg B which dissapears if I disable the Fwd Reverse input. The thing is that I configured the same on another PF 753 v2.005.33 in a similar machine with no issue. I know I can try DI Run Forward and DI Run Reverse instead but I don't want to. Any idea, please Thank you [/INST] The first thing that comes to mind is, why are you using such old firmware? V14.004 is the most current. There were SIGNIFICANT problems with firmware earlier than V4. If you cannot use V14, go as high as your application will permit. Look at the PM manual: https://literature.rockwellautomation.com/idc/groups/literature/documents/pm/750-pm001_-en-p.pdf Go to page 328 of the PDF. This chart documents DIGIN CFG B. I do not see a problem with your configuration based on this chart. Are you sure you have configured the IO as you've described? If you are absolutely sure about your configuration, then I suggest using ControlFlash+ to upgrade the firmware and try again. \\n </s>
