Vacuum pumps switch

[Thomas8607]

Hi!
I would like to ask for help.
I have 2pcs of vacuum pumps, I want to switch to operating hours, which one to go. Switching should only take place in a stationary position.
I have written 2 hours of operation time counter.
There are two outputs MB0: M101 engine start, MB1: M102 engine start.
I have outputs for both operating hours. If set to <= current operating hours, MB2 and MB3 outputs are active (SET).
How can I do my logic simply?
V130 PLC
Thanks!

Can you upload your program with what you've done so far?  Then we can have a look.

I'm not sure I understand exactly what you're trying to do, but if you want to alternate engines every 2 hours of operation, I would assign a coil to determine currently active engine (0=Engine 1, 1=Engine 2), then toggle the coil triggered by your accumulating register. Place the inverted contact for that coil in series with MB0 and direct contact in series with MB1.
