4.4.4 Startup Polls

You can enter start up polls for remote modules by using the "New Poll Mapping" box. This
function is the same as for the WI-I/O 9-x I/O modules. A start-up poll is a special message sent
when the WI-GTWY-9-xxx starts up. When the remote module receives a start-up poll, it will
immediately respond with update messages for all its inputs that are mapped to the WI-GTWY-9-
xxx. This allows the WI-GTWY-9-xxx to have correct values on start-up.

4.4.5 Polls to Remote Modules

It is possible for a WI-GTWY-9-xxx to send a poll to a remote module at other times apart from
start-up. A poll can be sent under the following events:
• based on a configurable time period
• based on real time clock
• on-demand by the host device.
For information on this configuration, refer to the next section on "Block Mappings".
4.5 Mappings from WI-GTWY-9-xxx to other WI-GTWY-9-
xxx Modules
Individual links between WI-GTWY-9-xxx modules can be configured under the "Mappings"
selection as described in the previous section. For example, if you want to transfer I/O Reg 144
in WI-GTWY-9-xxx#2 to I/O Reg 286 in WI-GTWY-9-xxx#3, you can enter the following
mapping:
Whenever I/O Reg 144 changed by the sensitivity amount, WI-GTWY-9-xxx#2 would send a
message to WI-GTWY-9-xxx#3 to write the value in I/O Reg 286. The problem arises if there
are a lot of these mappings. Each radio message only relates to one register-register link. If you
want to map 1000 registers from one WI-GTWY-9-xxx to another, then this could generate a lot
of radio messages.
