we used a plc having 256 i/o s. 224+(32 onboard).
with max of 7 modules (32 i/o each).now according to customer's
requirement we need 4 i/o's more.
we are using 80 cylinders. so for clamping declamping they used
160 read switches and connected all to the plc. one for each cylinder's
clamp and declamp action. but in actual the cylenders
are grouped and only 22 push buttons areused forclamping and 22 for declamping
my question is that how can we accomodate that extra 4 i/o's without changing the plc?
