For example, if you expand 

MNETCR.DATA

, you will see that it contains two 

UDTs, 

ReadData

 and 

WriteData

. Both of these are 600-element integer arrays 

by default. 

 

Notice that these UDTs are the data types used to declare the 

MNETCR.DATA.ReadData

 and 

MNETCR.DATA.WriteData

 controller tag arrays. 

Each UDT is commented in the 

Description

 column. 

 

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).
