Description of Changes
30 A J Nov 2004
Uncompressed disturbance recording added for
Courier/MODBUS/DNP 3.0 (added to IEC60870-5-103
protocol in 05D, 06B software)
Dual Characteristic DO/PU ratio Opto Inputs (DO/PU =
60/80% or 50/70%)
512 Event records (previously 250)
DNP3 evolution. Scan interval for binary inputs (object 01)
reduced from 5s to 0.5s. Scan interval for analogue inputs
(object 30) reduced from 2s to 1s. Improved minimum step
size of analogue input dead bands.
Modbus Time Transmission Format selectable as Standard
or Reverse for transmission of byte order.
DO/PU ratio changed from 95% to 98% for Over/Under
Voltage protection. Trip threshold changed from 1.05, 0.95
Vs to 1 Vs for Over and Under Voltage and NVD protection.
TMS setting of Under/Over Voltage protection reduced from
0.5 to 0.05.
Default labels changed for the digital inputs and outputs in
Input Labels and Output Labels menu. Changed to be more
generic - Input Lx, Output Rx.
Correction to false frequency protection start at power-up.
IEC60870-5-103. Status of summer bit now works correctly in
time sync command.
