Note the following points in the
configuration:
•
Note that no repeater address is
necessary between #1 and #96.
•
DIN2 (pump running signal) has
two mappings - a mapping to
DO1 at #2 (tank station) and DO2
at #96 (control station). When
DIN2 changes, there will be two
separate change messages
transmitted - one by radio to #2
and one by serial link to #96.
•
AIN1 (pump amps) is mapped to AO3 at #97 (control station).
•
An additional mapping has been entered - LOW VOLT has been mapped to DO8 at the
control station. This mapping is for future use - it will provide a low battery voltage
alarm for the pump station.
•
A Start-up poll has been configured for #2, as DO2 at the pump station is controlled from
the tank station. Note that a comms fail reset time of 11 minutes has been configured for
DO2. This means that if a message has not been received for DO2 within 11 minutes,
DO2 will reset and switch off the pump. The 11 min time was chosen as it means that two
successive update messages have to be missed before the pump is reset, and there is no
problems if the pump runs for 11 minutes during a system failure (the tank will not
overflow during this time).
Control Station Configuration
The 105S-3 module has the following configuration :-
Note the following points in the configuration :
•
The only mappings are Start-up polls. Note that there are two separate polls, one for each
remote module.
•
PO 3 has been configured as a PO. Its pulse output update time is the same as the PI
