Hello all,
I am not terribly experienced with all this stuff so forgive me if I am asking a silly question. Hopefully there is some simple answer here, but I am stumped.
I am wiring up a control panel with a 1769 L24ER-QB1B with a thermocouple module and integrated 16 ch input, 16 ch output. The PLC, thermocouple module, HMI and another peripherals are all talking to nicely and the programming seems to be working, but I cannot get the proximity switches to reliably work!
We are using CPS9H-AP-F Magnetic positioning switches PNP N.O. 5-28VDC. with a 24 VDC power supply
When I plug one into the input the PLC does not see it. Additionally assuming I put the switch on position 0, then when I take a voltage meter to the other inputs on the integrated card I get a reading of 22 volts on 1 through 7, zero on 8 through 15.
Any thoughts would be great!
