Hello all,
I am adding a 1771 VHSC card to an existing system in order to more precisely control part positioning. The problem I am having right now, is that I can not get the BTR to read the data from the VHSC.
I have the BTR and BTW setup as recommended in the manual with the NC enable bits in series with the commands. None of the enable bits ever seem to turn on. The VHSC is in slot 1 (power supply in slot 0 and the VHSC in the slot immediately to the right of that) and I believe that I have the R/G/S setup correctly, 0/1/0.
I am able to force the outputs on and off (the lights on the front of the card actually turn on and off) using the setup screen on the Block transfer instruction, but the BTW will only execute once. The lights for the encoder channels A and B flash when I jog the motor, but no count is ever recorded in the setup screen or in the register the BTR should be writing to.
I am not too familiar with block transfers so any help is greatly appreciated.
