ple, IR 00100 must be left ON continuously as long as IR 00001 is ON and
both IR 00002 and IR 00003 are OFF, or as long as IR 00004 is ON and IR
00005 is OFF. It must be turned ON for only one cycle each time IR 00000
turns ON (unless one of the preceding conditions is keeping it ON continu-
ously).
This action is easily programmed by using IR 22500 as a work bit as the op-
erand 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.

Programming Precautions
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 compli-
cated diagrams can be drawn with instruction lines, there must not be any
conditions on lines running vertically between two other instruction lines. Dia-
gram A shown below, for example, is not possible, and should be drawn as
diagram B. Mnemonic code is provided for diagram B only; coding diagram A
would be impossible.
