Function
Rotation control, which is used for tool rest and the like. The output is 0 for the
rotation in the clockwise direction, and the output is 1 for the rotation in the
counter clockwise direction.
Parameter
Input 1: enable on/off
Input 2: starting number. If the number is 0, the position number of rotational
equipment starts from 0; if the number is 1, the position number of rotational
equipment starts from 1.
Input 3: Whether to select a cutter nearby. If it is 0, the cutter will be selected in
the clockwise direction; if it is 1, the cutter will be selected nearby.
Input 4: target location type. When the value is 0, the current target location is
counted; when the value is 1, the previous location of target is counted.

Count result. The value of 0 represents the number of count locations, and the
value of 1 represents the count steps.
Parameter 1: maximum quantity of cutter rests.
Parameter 2: address of current position.
Parameter 2: address of target position
Parameter 4: address of count result. The meaning of count result is determined
by input 4 and input 5.

Operational Monitoring and Online
Modification for Ladder Diagram
The function of operational monitoring and online modification for the ladder
diagram, which is provided by PLC edit function, will monitor changes in the
status of each component in the ladder diagram, and force a modification of a
component status to achieve the goals of debugging.
Press “Ladder diagram monitoring” on the diagnosis interface, to access the
ladder diagram interface, as seen above. The buttons on this interface include
Ladder diagram diagnosis, Search, Change, Command, Load, Discard, Save
and Return.
The next sections offer more details.
