7-4 Data Conversion
The word data are regarded as unsigned (positive) data in the Modbus message. However, the actual value of the parameter may be
a negative value with decimal point. The high/low scale values for each parameter are used for the purpose of such conversion.
Let M = Value of Modbus message A = Actual value of the parameter
SL = Scale low value of the parameter SH = Scale high value of the parameter
M =
65535
× (A – SL)
SH – SL
)(
A =
SH – SL
× (M + SL)

(xx denotes the software version)
H’0X00 = Alarm status is off
H’0x01 = Alarm status is on
The alarm status is shown in MV2 instead of
MODE for models TEC-220 and TEC-920.
