Byte 0: Status Bits

Bit 0: External stop - "IES"
The "IES" bit is set if the digital input STOP has been activated. The bit
is reset by a new, valid job.
Bit 1: Reference point - "IRP"
The "IRP" bit is set if input REF has been activated during traversing
movements with bit RPA set. The bit is reset by a new, valid job.
Bit 2: Limit switch start - "ILSS"
The "ILSS" bit is set if input I - has been activated during traversing
movements with operating "Start backwards" mode. The bit is reset
by a job with operating "Start forwards" mode even if the limit
switch is still active.
Bit 3: Limit switch end - "ILSE"
The "ILSE" bit is set if input I+ has been activated during traversing
movements with operating "Start forwards" mode. The bit is reset by
a job with operating "Start backwards" mode even if the limit switch
is still active.
Bit 4: Distance to go - "IDG"
The "IDG" bit is set if the IP 267 does not supply the specified number
of pulses for a positioning job. The bit is reset after the complete
number of pulses have been output.
Bit 5: Pulse output - "IPQ"
The "IPQ" bit is set as long as the module outputs step pulses. The bit
is reset after the last pulse and the relevant pause has been output
(period duration of the step frequency).
