8.16.4 Troubleshooting
If the ZB4-601/609-IF1 receives no response from the PLC after a delay (VZ) of up to 500 ms (Timeout) after
STX the request (STX) is re-started.
If the command was not detected from the PLC (RECEIVE or SEND) or if another error is present in the data
package, the PLC must send a NAK (15
h
) within a VZ.
If the ZB4-601/609-IF1 does not receive a NAK or another character as ACK (06
h
) within a VZ, the request is
started.
