MBX Bridge Help
Cyberlogic Technologies Inc. - 11 -
An MBX device that can receive messages to be routed is called a source device.
Messages received by source devices are routed to other MBX devices called destination
devices. A given MBX device may be configured as a source device, a destination device
or both. An exception to this is that Serial MBX Master devices can only be configured as
destination devices and Serial MBX Slave devices can only be configured as source
devices.
A simple wizard-based editor creates a table of routing records that define how messages
are to be routed. Routing records are grouped according to their source device. Each
record contains a source section (Source Device, Slave Path, and Source Filter) and a
destination section (Destination Device, Network Type, Destination Routing, and
Timeout), as shown in the figure.
Filtering Incoming Messages
The source section defines a message filter, which determines what messages will be
accepted from the source device for routing through the bridge. To be routed according
to that record, an incoming message must match both the Slave Path and Source Filter
criteria. Filter fields may contain a single value, a range of values or an asterisk. The
asterisk indicates that any value is acceptable.
Any command message that passes through the filter will be routed through the bridge
as specified in the destination section. Otherwise, an error message is sent back.
Slave Path
The Slave Path field contains a single slave path number or a range of slave path
numbers that are compared with the slave path used by the incoming message. An
asterisk in a filter indicates that any slave path is acceptable. The same slave path can be
used in multiple routing records.
