This action is easily programmed by using IR 22500 as a work bit as the operand
of the DIFFERENTIATE UP instruction (DIFU(13)). When IR 00000 turns ON, IR
22500 will be turned ON for one cycle and then be turned OFF the next cycle by
DIFU(13). Assuming the other conditions controlling IR 00100 are not keeping it
ON, the work bit IR 22500 will turn IR 00100 ON for one cycle only.

The number of conditions that can be used in series or parallel is unlimited as
long as the memory capacity of the PC is not exceeded. Therefore, use as many
conditions as required to draw a clear diagram. Although very complicated dia-
grams can be drawn with instruction lines, there must not be any conditions on
lines running vertically between two other instruction lines. Diagram A shown
below, for example, is not possible, and should be drawn as diagram B. Mne-
monic code is provided for diagram B only; coding diagram A would be impossi-
ble.

Instruction 2

The number of times any particular bit can be assigned to conditions is not lim-
ited, so use them as many times as required to simplify your program. Often,
complicated programs are the result of attempts to reduce the number of times a
bit is used.
