7.2.16 Busy Timeout
0 to 65535
This parameter specifies the number of milliseconds to wait for the Modbus
Master port to become available. If the Modbus Master port is processing a
command received on another slave port, the busy flag will be set. The flag will
remain set until the communication transaction is complete. If the port does not
become available before the busy timeout expires, the message will be aborted
and an exception response (busy, try again later) will be returned to the
originating Master. If the Master port becomes available before this timeout
expires, the request will be routed to the Master port.
