Section 8.6: AB Tag Client
AB Tag Client Theory of Operations
:
The Allen Bradley Tag Client performs as a master to write and read data to and
from a Compactlogix or ControlLogix PLC. The required setup in the PLC program
is to create the needed Controller Tag Arrays noted in the mCoreSDR data map.
mCoreSDR supports Controller Tags and Controller Tag arrays with Integer,
Double Integer, and Real Floating-point data types.
Data is written to the PLC immediately on connection, but subsequent writes are
only made when the source data changes. Therefore, if you overwrite a value in
the PLC, mCore will NOT overwrite that value until the source data changes which
triggers a new write.
