range is used to set the range of the measurement associated with the transmission
output.
Only when the association type is active power, reactive power, power factor, or
frequency, the direction can be set to Bidirectional. 4mA represents 0 and 20mA
represents full scale when set to unidirectional. When set to Bidirectional, 4mA
represents the reverse range, 20mA represents the forward range.
Example 1: When the range is set to 1.000kW, if set to unidirectional, the output
of 4mA represents 0kW, the output of 20mA represents 1.000kW, the output of 12mA
represents 0.500kW; if set to bidirectional, the output of 4mA represents -1.000kW,
20mA represents 1.000 kW, 12mA represents 0kW.
Example 2: If the frequency F is set to Bidirectional, real-scale range is 50Hz ±
range, and 12mA represents 50Hz.
Association type is used to select energy which is associated to transmission
