Analog output to rexroth vt3006 card in Vision & Samba PLC + HMI Controllers & VisiLogic Software Posted October 24, 2017 · Report reply So I connected the solenoids to the vt card yesterday. Just for safety precaution I put power to card through a push button in case it tried to move too fast on me. I started by inputting my X on analog output and it works properly. The higher the number faster it moves and same way in the negative. So I wrote the code using the 4 prox switches as stages for a different setting to be stored into analog output and it works great.
