Cooper Bussmann 915U-2 Wireless Mesh I/O and Gateway User Manual
Rev Version 1.2.2
IO Table
Allows you to map each I/O to an output.
1. Click the
Local Name
field to see a drop-down list of all available I/O, or click the
Local Address
field to view a tabbed I/O selection screen that will allow you to
select an I/O point (input) that you want to map.
2. Select a destination I/O location. Click
Remote Name
for a drop-down list
of destination I/O names or
Remote Address
to open a drop-down list of
destination I/O locations.
NOTE A destination address must be selected before a remote name or
remote address can be selected.
I/O Count
Allows you to add more I/O points to the mapping. If you are using a write and a read
mapping, MConfig will automatically select consecutive registers that are shaded and
cannot be edited. When using a gather scatter mapping, MConfig will add mapping
entries which you must then edit by selecting the sending and destination I/O points.
Invert
Select this checkbox to allow the mapping to be inverted. For example, if the digital
input is “on” and the mapping is inverted, the output will be “off,” or if an analog input
is 4 mA and the mapping is inverted the output will be 20 mA. The invert applies to all
I/O in the mapping. Floating point and long values are not inverted.
Acknowledge
Select this checkbox to allow a second level of message acknowledgments to
be configured into the radio messaging. All normal WIBMesh protocol messages
use message acknowledgment, but these are radio-to-radio communications, not
source-to-destination. Selecting the Acknowledge checkbox allows the mapping to
be acknowledged when the end device receives the message. This is an end-to-end
acknowledgment, and is in addition to 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
Configures how often the mapping update messages (check signals) are sent. These
messages are in addition to the normal change-of-state updates that occur when an
input changes.
The default update time is 10 minutes, but it can be increased to a maximum of 18
days,12 hours, and 15 seconds, or decreased to a minimum of one second. Updates
can also be disabled by entering a time of zero or selecting the checkbox. Note that
the updates are only a check signal, and care should be taken when configuring the
update values with short update times (less than 5 seconds) because this will greatly
increase the amount of radio traffic.
Offset Time
Configures an offset time for the update mapping. The offset is used to stagger the
update transmissions at startup and at every update period so that the module does
not send all mappings at the same time. The default is 0, but the typical offset time is
around five seconds.
Response Time
(Read mappings only.) The countdown time before the module registers a
communications failure for the configured read mapping. When the timeout is
complete, the fail register is activated. This setting is normally used only with read
mappings communicating through repeaters, because a direct mapping will use the
update periods response as a timeout.
Change of State
Enable
When selected, the values are sent to their configured destination when a change-
of-state (COS) occurs and the value complies with any sensitivity blocks. If COS is
disabled, messages will only be sent on the update period.
