3-16 [GROUP] , [GROUPE]
GROUP and GROUPE should use in pairs.
GROUP and GROUPE don't have practical meaning; they are used to optimize the program
structure. So, add or delete these instructions doesn't affect the program's running;
The using method of GROUP and GROUPE is similar with flow instructions; enter GROUP
instruction at the beginning of group part; enter GROUPE instruction at the end of group part.
3-17 Programming notes
Contactor structure and steps
Even in the sequencial control circuit with the same function, it’s also available to simplify
the program and shorten the program steps according to the contactors’ structure. General
programming principle is: (a) write the circuit with many serial contacts on the top; (b) write
the circuit with many parallel contactors in the left.
Program’s executing sequence
Handle the sequencial control program by
【
From top to bottom
】
and
【
From left to right
】
Sequencial control instructions also encode following this procedure.
Dual output dual coil’s activation and the solution

Devices: None
Generally, GROUP and GROUPE
instruction can be programmed according
to the group's function. Meantime, the
programmed instructions can be FOLDED
or UNFOLDED. To a redundant project,
these two instructions are quite useful.
