The group diagnostic data of the modules can also be accessed cycli-
cally.

5.5.2 Reading out the bus coupler diagnostic data

You can find a description of the diagnostic data for the valve zone in
section g 6. Structure of the Valve Driver
The diagnostic data for the I/O zone is described in the system descrip-
tions of the individual I/O modules.

5.6 Extended Diagnostic Data of the I/O Modules

In addition to group diagnosis, some I/O modules can send extended diagnostic
data with a length of up to 4 bytes to the controller. The total data length can
thus be up to 5 bytes:
Byte 1 of the diagnostic data contains the group diagnosis information:
• Byte 1 = 0x00: No error has occurred.
• Byte 1 = 0x80: An error has occurred.
Bytes 2 to 5 contain the extended diagnostic data of the I/O modules.
The extended diagnostic data can be read out from Input Register 80 (50hex).
