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 =

*3: The PROG code is defined by 5.XX, where XX denotes the software version number.
For example : PROG=5.10 means the product is TEC-410 with software version 10.
*4: The least significant bit (LSB) of ALM shows the status of output 1.LSB=1 if output
1 is ON (normal condition). The second bit of ALM shows the status of output2.
