Controlling the X-gateway from the Network

Some functions in the X-gateway can be controlled from the network by setting the correspond-

ing bits in the Control Word, which (if enabled) takes up the first two bytes of the input area (data

coming from the network).

The Control Word is disabled by default and must be enabled for each network separately via

Anybus Configuration Manager. When enabled, specific actions may be required in order for

the X-gateway to start exchanging data.

Master Mode (master configurations only)

If a network interface is confgured as a network master, these bits indicate the current operation

mode of the master to the other network.

The exact definition depends on the network interface type. See the Network Guide for the re-

spective interface for more information.

Reset

Can be used to reset the Anybus X-gateway.

Bit set (1) = Restart the gateway and re-initialize both network interfaces

Bit cleared (0) = No action

Network-specific Controls

Some network interfaces may provide additional methods of controlling the X-gateway from the

network. See the Network Guide for the respective interface for more information.

2.5

Error Handling

If a network goes offline the X-gateway can either freeze (keep the current value) or clear (set

to zero) the data from the network that has gone offline. Which action to take can be selected

via Anybus Configuration Manager.
