Binary Command Acyclic
The function blocks "Binary Command Acyclic 0 ...1" provide access to the command bytes 0 ... 1 acyclically sent via fieldbus
(e.g. PROFIBUS) to the UMC.
Acyclic commands are usually sent from a service tool upon user request.
The function block BinAcyclicCmd0 behaves slightly differently to BinAcyclicCmd1. By default it is used to receive start/stop
commands sent from the FIM. Therefore commands received at the block are only available for one application cycle at its outputs.
Then the outputs are cleared automatically. The mapping from the command buttons to the outputs is as follows:
Bit 0: Fast Reverse
Bit 1: Reverse
Bit 2: Stop
Bit 3: Forward
Bit 4: Fast Forward
Bit 5: Reserved
Bit 6: Reserved
Bit 7: Fault Reset
The command bytes can be sent to Slot 4/Index 54 Byte 0 (BinAcyclicCmd0 ) and Byte 1 (BinAcyclicCmd01). The total data
block length is 8 Bytes whereas the last 6 bytes are unused.
