A status query was also set in the examples given here. In example 1, the status
query is performed for the I/O module. The status word (byte 0) is at 0x48; an
error has occurred in the I/O module (ERROR, ERR_BK). Byte 2 is at 0x40, i.e.,
the rotary field is not correct, counterclockwise.
In example 2, the status query is performed for phase L1. The status word (Byte
0) is at 0x41; an error has occurred at phase L1 (ERROR, ERR_L1). Byte 2 is at
0x08, i.e., the voltage signal at phase L1 is outside the range measurable by the
I/O module and has been clipped. In addition, byte 1 is at 0x80. This means that
the measured values of the collection are not yet stable. The transient reaction
period must first elapse before the measured values are stable.
5.4.3
Transient Reaction Measured Values
Transient reaction processes must be taken into account when switching
measured value collections in order to obtain stable measured values in the
process image. You can check whether the measured values are stable with the
“WARN” flag in the status word (byte 1). You can find these initialization times in
section “Technical Data.”
