Hi all,
this is my first thread on here, completely new to plc. Have been given a 1769 L24ER QB1B to play with.
I have a PA2 power supply and a few I/O modules in the rack, (Photo attached)
I have RSlinx and studio 5000, Factory talk me.
The problem I have is when I switch on the 1769-PA2 power supply, I cannot get any LEDs to light on the controller itself, therefore cannot connect it to rslinx and practice downloading some programs to the plc.
I have run 2 cables from the power supply (PWR OUT+24Vdc) to the +24vdc on the controller and likewise with the COM wire but still no power.
Hopefully a schoolboy error someone can point out!
thanks in advance.
