Control

 flag area 

This memory area enables control by the corresponding operation commands. The data structure is shown below. 

Each bit corresponds to a counter module ID.

1. About the operations update parameter, reset, recall preset, start, and load reference point 

The operation sequence is as follows. 

Each has a control flag and a corresponding completion flag. When the PLC turns the control flag ON, the MG80-

SC reads the flag and executes the corresponding operation. When the operation is completed, the completion bit 

is written back.   

The PLC checks the completion bit and turns off the control flag. The MG80-SC checks the control flag and turns 

off the completion flag. 

2. The operation sequence for requesting measurement data is the same as above. 

For measurement data requests, if any bit is set to ON, the MG80-SC writes the measurement data of all 

connected counter modules. 

3. When the bit is turned ON for the corresponding hold function (pause or latch), 

the hold function is enabled.
