a = 0.006
b = -4096
Vt = 0.006 * V - 4096
For max voltage 500000 V * 2.4 = 1200000 V, we transmit
Vt = 0.006 * 1200000 - 4096 = 7200 - 4096 = 3104
SETTINGS  PRODUCT SETUP  COMMUNICATIONS  IEC 60870-5-103  IEC103 COMMANDS
Commands are received as General Command (Type Identification 20). The user can configure the action to perform when
an ASDU command comes.
A list of available mappings is provided on the B90. This includes 64 virtual inputs (see the following table). The ON and OFF
for the same ASDU command can be mapped to different virtual inputs.
Each command is identified by the unique combination made by the function type (FUN) and information number (INF). If
the master sends an ASDU command that does not have the FUN and INF of any configured command, the relay rejects it.
