Example 3:
Control Action
The following example uses the 1-second clock pulse bit (25502) so that the
execution condition produced by 00005 is shifted into a 3-word register between
IR 010 and IR 012 every second.

The following program is used to control the status of the 17th bit of a shift regis-
ter running from AR 00 through AR 01. When the 17th bit is to be set, 00004 is
turned ON. This causes the jump for JMP(04) 00 not to be made for that one
cycle, and AR 0100 (the 17th bit) will be turned ON. When 12800 is OFF (i.e., at
all times except during the first cycle after 00004 has changed from OFF to ON),
the jump is executed and the status of AR 0100 will not be changed.

When a bit that is part of a shift register is used in OUT (or any other instruction
that controls bit status), a syntax error will be generated during the program
check, but the program will executed properly (i.e., as written).
The following program controls the conveyor line shown below so that faulty
products detected at the sensor are pushed down a shoot. To do this, the execu-
tion condition determined by inputs from the first sensor (00001) are stored in a
shift register: ON for good products; OFF for faulty ones. Conveyor speed has
been adjusted so that HR 0003 of the shift register can be used to activate a
pusher (00500) when a faulty product reaches it, i.e., when HR 0003 turns ON,
00500 is turned ON to activate the pusher.
