DATAFLOW RTU
6.4 Load the FULL SCADA CONFIG, using RTU Programming Software. The configuration
is stored in RTU RAM, which has a large capacitor to hold the information in memory for
an extended period of time - 3 months or longer. If the stored configuration is lost, reload
it with the RTU Programming Software.
6.4.l If the application requires a MODBUS controller to download the FULL SCADA CONFIG,
consult RITRON for the proper procedure. This procedure varies depending on the type of
MODBUS controller you are using.
CAUTION:
For Firmware Versions earlier than 3.25
(released in the 2"d quarter of 1998), in a SCADA
system, use unit ID's or MODBUS addresses from 40 to 255 only. Communication errors may
result from using ID's and addresses from 1 to 39.
