3.3 Using Controller Tags
You can use controller tags to:
 View read and write data that is being transferred between the module and
the processor.
 View status data for the module.
 Set up and trigger special functions.
 Initiate module restarts (Warm Boot or Cold Boot).
3.4 Controller Tag Overview
Controller Tag Description
MNETC.DATA MNET input and output data transferred between the processor
and the module
MNETC.CONTROL Governs the data movement between the PLC rack and the
module
MNETC.STATUS Status information
MNETC.UTIL Block statistics and generic tags used for internal ladder
processing (DO NOT MODIFY)
The following sections describe each of these controller tag structures in more
detail.
3.4.1 MNETC.DATA
The controller tags in MNETC.DATA hold data to be transferred between the
processor and the MVI56E-MNETC module. This read and write data is
transferred between the processor and module as "pages," or blocks, of data up
to 200 words long.
The data types for the MNETC.DATA.ReadData and MNETC.DATA.WriteData
controller tag arrays are integer arrays containing variable numbers of elements.
Controller Tag Data Type Description
ReadData INT[x] Data read from module. Array size is equal
to the size set in the configuration.
WriteData INT[x] Data to write to module. Array size is equal
to the size set in the configuration.
