Acyclical diagnostic data of the valve drivers via SDO

You can read out the diagnostic data of the valve drivers byte by byte or as a string.
To read out the diagnostic data of the valve drivers byte by byte:
Enter the following object data in the "Read SDO" field of the PLC configuration software in object
0x23nn.
Table 22: Reading out the diagnostic data of the valve drivers byte by byte with object 0x23nn
Object no. Sub-object no. Contents

0x23nn 0
1
1)
When a sub-object without a diagnostic byte is accessed, the value 0 is returned.
2)
nn = module no. 00 to 2A (hexadecimal), corresponds to 00 to 42 (decimal)
To read out the diagnostic data of the valve drivers as a string:
Enter the following object data in the "Read SDO" field of the PLC configuration software in object
0x33nn.
Table 23: Reading out the diagnostic data of the valve drivers as a string with object 0x33nn
Object no. Sub-object no.

nn = module no. 00 to 2A (hexadecimal), corresponds to 00 to 42 (decimal)
You will receive 1 data byte as a response. This byte contains the following information:
Byte 1 = 0x00: No error has occurred.
Byte 1 = 0x80: An error has occurred.
