Greetings,
I replaced a 1305 drive with a PF70 drive. The 1305 was controlled by a PLC5 via RIO using a 1203-GD1 Remote I/O Communications Module. The PF70 has a 20-COMM-R.
Of course, I had to swap some words around in the PLC5. The 1203 uses word 0 for logic and word 1 for speed reference. The 20-COMM-R is just the opposite.
The PLC5 had a MOV command to move the speed reference to word 1. I need to use a BTW to move the speed reference to word 0.
I must admit, this PLC5 is a little before my time, so bear with me please.
The word I need is O:044. That would be Rack 4, Group 4, Module 0, right? This is how I have the BTW configured using control block BT9:1 and the Data file is N27:0. N27:0 has the correct value, but O:044 does not. Changing N27:0 does not change O:044
What have I done wrong?
