Details of T_COM

Exchange Objects of the IODDT

The T_COM_EIP IODDT supports both implicit and explicit exchange objects:

Implicit exchange objects are automatically exchanged at each cycle of a task associated with the channel.
Explicit exchange objects can be reached via explicit messaging controlled either by program logic, or by operator commands.

Exchange objects are %I, %IW, %M and %MW.

The tables below presents the various implicit and explicit exchange objects of IODDT T_COM_EIP, as supported by the BMX NOC 0401 communication module.

The parameters r, m, and c shown in the following-tables represent the topological addressing of the module. Each parameter has the following signification:

r represents the rack (or station) number
m represents the module (or slot) number
c represents the channel number
