16.1.2.4 Indicator word ANZW
Status and error reports are created by the handling blocks:
n by the indicator word ANZW (information at order commissioning).
n by the parameter error byte PAFE (indication of a wrong order parameterization).
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
n Bit 3 ... Bit 0: Error management CPU
– 0: no error
– 1 ... 5: CPU-Error
– 6 ... 15: CP-Error
n Bit 7 ... Bit 4: reserved
1 State management CPU
n Bit 0: Handshake convenient (data exists)
– 0: RECEIVE blocked
– 1: RECEIVE released
n Bit 1: order commissioning is running
– 0: SEND/FETCH released
– 1: SEND/FETCH blocked
n Bit 2: Order ready without errors
n Bit 3: Order ready with errors
Data management handling block
n Bit 4: Data receive/send is running
n Bit 5: Data transmission active
n Bit 6: Data fetch active
n Bit 7: Disable/Enable data block
– 1: released
– 0: blocked
2 ... 3 Length word handling block
In the "length word" the handling blocks (SEND, RECEIVE) store the data that has
already been transferred, i.e. received data in case of a Receive order, send data when
there is a Send order. The announcement in the "length word" is always in byte and abso-
lute.
Those bits announce the error messages of the order. The error messages are only valid
if the bit "Order ready with error" in the status bit is set simultaneously.
