are greyed out and cannot be edited. When using a Gather/Scatter Mapping it will add
mapping entries which you must then edit and select sending and destination I/O points.

Invert

This will allow the mapping to be inverted. E.g. if the digital input is ‘On’ and the

mapping is inverted the output will be

‘Off’, or if an analog input is 4mA and the mapping

inverted the output will be 20mA, or vice versa. The

‘Invert’ applies to all of the I/O in the

mapping. Note: Floating Point and Long values will not be inverted.

Acknowledge

Allows a second level of message acknowledgments to be configured

into the radio messaging. All normal WIBMesh protocol messages use message
acknowledgment however this is radio to radio communications and not source to
destination. Selecting the

‘Acknowledge’ box will allow the mapping will be

acknowledged when the end device receives the message. This is an end-to-end
acknowledgement, and is over and above the normal hop-by-hop frame
acknowledgment between links. Note: Enabling this option will increase the amount
of radio communications and care should be taken in larger systems.

Update Time - This is the period of time that the mapping update messages (check
signal) are sent. This is outside of the normal change of state updates that occur when
an input changes.

Offset Time - Configures an offset time for the update mapping. It is used to stagger
the update transmissions so on start-up and every update period the module does not
send all mapping at the same time. Default will be 0 however the typical time would be
around 5 seconds.

Response Time (Read Mappings only) - The time the module counts down before
registering a communications failure for the configured read mapping. When the timeout
is complete, the Fail Register will be activated. Normally only used with read mappings
communicating through repeaters. This is because a direct mapping will use the update
periods response as a timeout.

Change of State (COS) Enable - When enabled the values will be sent to its
configured destination when a change occurs and the value complies with any
Sensitivity blocks. If COS is disabled, messages will only be sent on the update period

Change of State (COS) Delay

COS Delay is a time period that the message is

deferred from being sent. Its use is to try to reduce the amount of radio traffic by holding
off the transmission to allow more I/O COS to the mapping.

Change of State Reset Update Timer- If this option is enabled the Update Time period
will reset when a COS is received in-between configured updates, meaning the next
update will not be sent until a further update period has elapsed - Can be used reduce
the amount of radio traffic produced when multiple mappings are configured.

Registers - Fail Registers

Allows you to configure a register location that will indicate

a communication failure for the configured remote Destination Address.

Note:

‘Acknowledge’ must be enabled for fail registers to work. Also Fail Register

can only be a Digital Output or an internal Bit registers (10501, 501, etc.).

Registers

– Force Register – the Force Register is an I/O location that will force the

Mapping to be sent when written to. External devices, i.e. Modbus Master/Clients can
