Good day all. I'm in the process of removing old I/O from my PLC-5 as it is no longer used. For example: I would like to remove "FIC_1601 Mass Flow Setpt HF Line 1 LT_GEN_3". PLC-5 sends SP to the mass flow controller (MFC)using analog output module and address N14:401, and then the MFC sends the flow rate (PV) back to the PLC-5 analog input module using address N12:231. Doing a find all I see that these addresses are not being used by my project, however, the BTR and BTW are still active. What I would like to know is, if I physically remove the wiring for this particular analog I/O, will the system still function properly even though the BTR will no longer have data for this address? Thank you.
