Section 12.5: AB Tag Client - PLC Setup and Sequence of Operations
Note: mCore will not perform calculations unless a License file AND at least 1 Viewer
file is uploaded, set to active, and clicked Store Changes.

The PLC Programmer will need to first setup their PLC with the following Tag
Arrays. Pay special attention to the spelling, capitalization, and the use of
underscores instead of spaces for each tag array name as they must be identical
in the PLC program. A Data Map will be available to show what each array index is
for what.
Array Name
Data Type [Quantity]
ACI_Inputs
REAL [137]
ACI_Control
REAL [25]
ACI_Misc
REAL [30]
ACI_Cond
REAL [30]
ACI_ErrorArray
DINT [100]
ACI_LoadArray
REAL [100]
ACI_FlowArray
REAL [100]
ACI_StageArray
REAL [180]
ACI_ThrowArray
REAL [300]
ACI_CylHEArray
REAL [400]
ACI_CylCEArray
REAL [400]
ACI_Ranges
REAL [25]
ACI_PLC_REQ
INT [4]
ACI_PLC_ACK
INT [4]

Have the PLC write a 1 to ACI_PLC_REQ[0] array index to tell mCore to run
calculations. mCore will first read the compressor data from the PLC’s ACI_Inputs
array and then start the calculation process.
