RK512 communication - Indicator word ANZW
Status and error reports are created by the handling blocks:
•
by the indicator word ANZW (information at order commissioning).
•
by the parameter error byte PAFE (indication of a wrong order para-
meterization).
The "Indicator word" shows the status of a certain order on a CP.
In your PLC program you should keep one indicator word for each defined
order at hand.
The indicator word has the following structure:
Byte Bit 7 ... Bit 0
0 Error messages CP
00h: no errors
17h: Message too long
0Ch: Frame error
07h: Acknowledgement delay
0Ah: DBL exceeded
1 Status management CPU
Bit 0: not used
Bit 1: order is running
0: SEND/FETCH released
1: SEND/FETCH blocked
Bit 2: Order ready without errors
Bit 3: Order ready with errors
Bit 7 ... Bit 4: not used
In this byte error messages of the CP are entered. The error messages are
only valid if the bit "Order ready with error" in the status bit is set
simultaneously.
The following error messages may occur:
00h no error
If the bit "Order ready with error" is set, the CP had to reinitialize
the connection, e.g. after a reboot or RESET.
17h Message too long
The received message is too long. Maximally 1024byte user
data may be transferred.
07h Acknowledgement delay
The message was not acknowledged within the acknow-
ledgement delay time.
0Ah DBL exceeded
The number of block repetitions, which may be set at the
parameter "Data block length DBL" was exceeded.
