Controlling The X-Gateway From The Network; Error Handling - HMS Anybus X-Gateway User Manual

Description
2.4

Controlling the X-gateway from the Network

Some functions in the X-gateway can be controlled from the network by setting the
corresponding 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.
(MSB)
bit 15 bit 14 bit 13 bit 12 bit 11 bit 10
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 documentation for the
respective 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
2.4.1 Network-specific Controls
Some network interfaces may provide additional methods of controlling the X-gateway from the
network. See the documentation 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.
