Appendix A System Example
man_905_2.1.doc Page 57
Note the following points in the configuration :
• The configuration software used was CFG105-1.EXE as the module is a 105U-1.
• The system address is 10587 (same as before) and unit address is 1.
• DIN1 (pump fault signal) is mapped to Out1 (DO1) at #96 which is the control station. Note
that no repeater address is necessary as there is a direct link 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 Out3 at #97 (AO3 at control station).
• An additional mapping has been entered - LOW VOLT has been mapped to Out8 at #96
(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).
