f
Allocated to instruction
keys on the Program-
ming Console. These
need not be specified
with function codes.
Code Special instructions
specified with function
codes.
Differentiated Instructions
Differentiated instructions can sometimes be used for CPM1A
special instructions. Instructions marked with (@) in the mne-
monics can also be used as differentiated instructions. Here the
input rise time (shift from OFF to ON) is used to execute the
instruction in just one cycle.
To specify an instruction, press the NOT Key after the function
code.
Example: Specifying the @MOV (21) instruction

Function
Outputs the result of logic to a
bit.
Reverses and outputs the re-
sult of logic to a bit.
Force sets (ON) a bit.
Force resets (OFF) a bit.
Maintains the status of the
designated bit.
Turns ON a bit for one cycle
when the execution condition
goes from OFF to ON.
Turns ON a bit for one cycle
when the execution condition
goes from ON to OFF.
Function
---
Required at the end of the pro-
gram.
If the execution condition for
IL(02) is OFF, all outputs are
turned OFF and all timer PVs
reset between IL(02) and the
next ILC(03).
ILC(03) indicates the end of an
interlock (beginning at IL(02)).
If the execution condition for
JMP(04) is ON, all instructions
between JMP(04) and
JME(05) are treated as
NOP(00).
JME(05) indicates the end of a
jump (beginning at JMP(04)).
Function
An ON-delay (decrementing)
timer.
A decrementing counter.
Increases or decreases PV by
one.
A high-speed, ON-delay
(decrementing) timer.
