Diagnostic State
ƒ 0 = Normal Operation or not in data exchange with Status Register [0] Bit
0x20 set.
ƒ 1 = Not in data exchange state with the Status Register [0] bit 0x20 not set or
normal operation with the Status Register [0] bit 0x20 not set.
ƒ 3 = Not in a defined state or in module state 1, 2 or 3.
ƒ 4 = Normal operation with Status Register [0] bit 0x20 set
PROFIBUS Input Counter
Input counter is incremented each time the input data is updated.
PROFIBUS Output Counter
Output counter is incremented each time the output data is updated.
Last Global Command
The value of the last global command code received from the master.
Bit Designation Significance
0 Reserved
1 Clear_Data With this command the ASCI output data is deleted in data transfer
buffer and is changed to next transfer data buffer contents.
2 Unfreeze With 'Unfreeze': freezing input data is cancelled.
3 Freeze The ASCI input data is fetched from next transfer buffer to data
transfer buffer and frozen. New input data is not fetched again until
the master sends the next 'Freeze' command.
4 Unsync The 'Unsync' command cancels the 'Sync' command.
5 Sync The ASCI output data transferred with a WRITE_READ_DATA
telegram is changed from data transfer buffer next state buffer. The
following transferred output data is kept in data transfer buffer until
the next 'Sync' command is given.
6,7 Reserved The Reserved designation specifies that these bits are reserved for
future function expansions.
