Combination Of These Instructions:
This format uses EXAMINE elements that address bits in the remote
station processor. These elements control remote station data table bits as
follows:
-] [- EXAMINE ON - This rung element instructs the remote station
communication adapter module to turn the addressed bit on.
-]/[- EXAMINE OFF - This rung element instructs the remote station
communication adapter module to turn the addressed bit off.
Program these elements immediately after the command code. Any
combination of these elements may make up this type of command rung.
Where necessary, BRANCH START instructions and a BRANCH END
instruction can be used to fit these elements into the display area of the
programming terminal. For practical reasons, do not exceed this display
area. Multiple rungs of this type can be used as necessary.
The delimiter rung ends the communication zone of program. With
PLC-2 family processors, this rung always has the format shown in
