8. COMMUNICATION FUNCTIONS
(2) Writing processed data
When written data is handled as a decimal number, the decimal point position must be specified. If it
is not specified, data cannot be written. When data is handled as a hexadecimal number, specify "0"
for the decimal point position.
The data to be sent is as follows:
0
Data is transferred in hexadecimal.
Decimal point position
0: No decimal point
1: Lower first digit
2: Lower second digit
3: Lower third digit
4: Lower fourth digit
5: Lower fifth digit
How to process set data to the value of "15.5" is explained here by way of example.
Since the decimal point position is the second digit, the decimal point data is "2".
As the data to be transmitted is a hexadecimal number, the decimal data is converted into a
hexadecimal number.
115 9B
Hence, "0200009B" is sent.
