CAB720 communication driver store the same data in WORD, DWORD, FLOAT memory, but the data formats are different.

 

Note) When readed data to CAB720 controller, save '1' value at WORD 20 memory.

You have to clear periodically by 'Digital Output Tag'. (Extra1 = #mem# , ... )

 

2. Writing settings

CAB7200 communication driver don't support write settings.(read only controller)
