PID Pump Control s7-1500

Hello,

I have 6 set of pumps controlled with 6 G120X from S7-1513 via profinet. When I set a pressure of 6 bars for required pressure motors will start running one by one that has worked least, and when set point is reached they will maintain the pressure. How can I wrote this PID and if one of the motor is stopped due to overload (ex fuse failure) the other motor had to step in and run less than 1 sec.  Is there any example some one could suggest ?

Best Regards 

Hello,

Check this link for motor staging application Staging

But its not with PLC PID function its based on drive functon 

we have used this before for our application 

maybe you can get some idea
