Byte 3: Error Flags - Siemens SIMATIC S5 Manual

Communication Between the CPU and the IP 266
Example 2:
The IP 266 receives a request to position the axis in a controlled mode (mode 1, 2
or 7). All status data is returned in binary. The machine data is correct. There is no
reference point.
The IP 266 returns the following in byte 2:
Byte Bit 7 Bit 6 Bit 5
2 1 0
No reference point
Machine data is OK
Job is in progress

Byte 3: Error Flags

IP 266 errors are flagged in bits 0 to 4 of byte 3. The error code is right-justified
and in binary. Use KH (hexadecimal constant) format to read the error code. You
will find a list of error messages in Section 10.
The error codes forwarded to the PLC are identical to those output by COM 266.
