Purpose
Subtracts the current value of one from the TARGET value of another block.
Syntax
SUBTAR block FROM block
Example
To subtract the current value of AI3 from the target value of PID5, enter:
SUBTAR AI3 FROM PID5
NOTE: When specifying a Ramp block, SUBTAR subtracts the value from the first target value of the block, SUBTAR2 subtracts the value from the second target value, and SUBTAR3 subtracts the value from the third target value. If a target value that is outside the Ramp block's EGU range, the Ramp block clamps the value to its high and low EGU limits. AO blocks to not have target values. When using blocks like AO or AI, which do not have target values, use SUBOUT command.
