10.5.2 Conditioned binary actions instructions
There are 3 instructions: SET, RES and CPL, that are used to change the status of the indicated
resource.
Their programming formats are:
=SET
If expression = "1", it sets the resource to "1".
If the result of the logic expression is a "1", it sets the indicated resource to "1". If the result is "0",
it does not change the resource.
Example: CPS T2 EQ 100 = SET B0R100
When the timing of timer T2 reaches 100 milliseconds, it sets bit 0 of register R100 to "1".
=RES
If expression = "1", it sets the resource to "0".
If the result of the logic expression is a "1", it sets the indicated resource to "0". If the result is "0",
it does not change the resource.
Example: I12 OR NOT I22 = RES M55 = NOT RES M65
When the result of the logic expression is a "1", the PLC sets "M55 = 0"; but does not change M65.
If the result of the logic expression is "0", then the PLC does not change M55; but it sets "M65 = 0".
=CPL
If expression = 1, it complements the resource.
If the result of the logic expression is a "1", it complements the status of the indicated resource. If
the result is "0", it does not change the resource.
Example: DFU I8 OR DFD M22 = CPL B12R35
Every time an Up Flank (leading edge) is detected at input I8 or a down flank (trailing edge) in
mark M22 the PLC will complement the status of bit 12 of register R35.
