3.2 Module Data Object (DFCMModuleDef)
All status and variable data related to the MVI56-DFCMR is stored in a user
defined data type. An instance of the data type is required before the module can
be used. This is done by declaring a variable of the data type in the Controller
Tags Edit Tags dialog box. The object has the following structure.
Name Data Type Description
ModDef DFCMModule Backplane operation characteristics
Port DFCMPort[2] MB settings for each port
P1Cmd DFCMCmd[100] Master Command List for Port 1
P2Cmd DFCMCmd[100] Master Command List for Port 2
InStat DFCMInStat Status information in each read block
ReadData INT[600] Data read from module
WriteData INT[600] Data to write to module
BP DFCMBackplane Data to handle backplane logic
P1Slaves INT[256] Port 1 slave status values
P2Slaves INT[256] Port 2 slave status values
P1DataFileMap DFCMDataFileMap[50] Port 1 Data File Mappings
P2DataFileMap DFCMDataFileMap[50] Port 2 Data File Mappings
