AND (ANI) command:
A series configuration in which a single device is connected with one device
or a block.
AND command
AND command
ANDP, ANDF also have structures like this, but their action occurs at the rising and falling edge.
OR (ORI) command:
A single device is connected with one device or a block.
OR command
OR command
OR command
ORP, ORF also have identical structures, but their action occurs at the rising and falling edge.
ANB command:
A configuration in which one block is in series with one device or block.
ANB command
ORB command:
A configuration in which one block is in parallel with one device or block.
ORB command
In the case of ANB and ORB operations, if a number of blocks are connected, they should be
combined to form a block or network from the top down or from left to right.
MPS, MRD, MPP commands:
Branching point memory for multiple outputs, enabling multiple,
different outputs. The MPS command begins at a branching point, where the so-called branching
point refers to the intersection of horizontal and vertical lines. We have to rely on the contact status
along a single vertical line to determine whether the next contact can give a memory command.
While each contact is basically able to give memory commands, in view of convenience and the
PLC's capacity restrictions, this can be omitted from some places when converting a ladder diagram.
The structure of the ladder diagram can be used to judge what kinds of contact memory commands
are used.
