Anybus CompactCom 40 - PROFINET IRT Transparent
Ethernet
• Command Details
If the I&M0 Filter Data is of no interest, the Data Field is left out (command length = 0).
The command may contain one or several I&M0 Filter Data entries. The maximum amount of entries depends
on the application. For a 256 bytes message channel the maximum amount of entries is 51 (256 / 5 = 51). For a
1524 bytes message channel, the maximum amount of entries is 304 (1524 / 5 = 304).
IMPORTANT
For submodules to be listed in the I&M0 Filter data, the command must be sent when the
Real Identification has been determined. This means that for the "ADI Based RI" method,
the command must be sent when the module has shifted to WAIT_PROCESS state. For the
"Application specific RI" method the command can be sent in SETUP state but after the plugging
of modules/submodules is finished (Plug_Module/Plug_Submodule).
The table below contains two entries as an example.
