T.Etheridge Posted July 27, 2020 Report Share Posted July 27, 2020 Hi all, Just wondering if there is an easy way to check if a expansion module is connected and active, i had a look through the SB's but couldn't find anything. I'm using the IO-PT400 expansion. I have got everything working as required but it just requires a few more lines in the ladder. Thought a SB for expansion connected would be alot simpler.
