Hydraulics with amplifier cards

Recommended Posts

Hello, I'm in the process of doing program for a blow molding machine. This one has rexroth vt5006 s16 r1 proportional amplifier cards for molds open and close valves. Used to have a maco 8000 system and I'm installing v1210 visi system. I'm trying to wrap my head around how to properly use cards with plc. Hoping someone might get me started in right direction. Here is what I know.

Inputs to plc:

Mold open prox, mold  partially closed prox, mold close prox, and mold completely closed prox. 

Outputs from plc to card:

Close mold relay on terminal 12c of card, close mold cushion relay on terminal 12a, open mold relay on terminal 16a, and open mold cushion relay on 16c.

Outputs from card to solenoids:

Open mold sol on terminals 2a and 32a of card, close mold sol on 2c and 32c.

The cards are still wired to valves and whatever else is there except for outputs from plc to card, for now anyways. I'm more interested in the logic for controlling them. If anyone can help, I'd appreciate it. Thank you.
