To read out the bus coupler data as a string:
Enter the following object data in the "Read SDO" field of the PLC configuration software in object
0x3012.

You can find a description of the diagnostic data for the valve zone in chapters"6 7" starting
on page 92. A description of the diagnostic data for AV-EP pressure regulators can be found
in the operating instructions for AV-EP pressure regulators. The diagnostic data for the I/O zone
is described in the system descriptions of the individual I/O modules.

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 only be accessed acyclically with SDOs.
You can read out the diagnostic data of the I/O modules byte by byte or as a string.
To read out the diagnostic data of the I/O modules byte by byte:
Enter the following object data in the "Read SDO" field of the PLC configuration software in object
0x23nn.
