CJ-series DeviceNet Units Operation Manual for NJ-series CPU Unit(W497)
You can use this table to store the present, maximum and minimum communications cycle times in
milliseconds.
All the values in this table are cleared from the Unit and the maximum and minimum values are updated
with new values of when
*_Sw1CycleTmClrCmd
(Communications Cycle Time Reference Table Clear
Switch) is changed to TRUE.
In the case of automatic setting (default), the communications cycle time setting value is set to 0.
You can access the settings (area and size) for a maximum of four blocks (OUT block 1, OUT block 2,
IN block 1, and IN block 2) in the Master User-set Allocations Reference Table.
The OUT 1 and IN 1 block settings can be referenced if CX-Integrator is not being used.
