6.12.5.3 PLUS signals timing diagram
The following sequence diagram indicates the general sequence of PLUS communication in the "Work
and Send" (WaS):

6.12.5.4 Timing diagram for system errors
As the PLC interface has only one 16-bit word for transmission of one channel error code, the errors
active in the system are transmitted multiplexed via the interface. For this purpose, the error code and the
channel number are generated by the KE and the ChnErr signal is set while waiting for acknowledgement
of acceptance by the PLC by the rising edge at ChnErrAck. With this, the error is transmitted into the
PLC. The KE removes the signal again and waits for confirmation by the PLC (falling edge of ChnErrAck).
If additional errors are active, they are transmitted respectively. If no more error is active, error code 0 is
transmitted.
