| The SR750 uses COMX and the MODBUS
protocol. The Data Loggers' address and communications parameters
can be found by interrogating the unit using the front panel
controls , however this is difficult to drive and an easier method
is to use an interface program available from
www.ge.com/edc/pm/catalog/index The RS232 cable must be straight
through no crossover.
The citect.ini file must include the line [MODBUS]InitType = 3
(Mandatory for communications).
When setting up your tags the tag type must be INT within the
range 30001 to 49999 and the tag reference in the manual (SR750/760
Feeder management relay Instruction manual P/N 1601-0044-A9) must
be converted to decimal and add 1.
