Chapter8 Communication Function
Remark
1) Numerical data of frame(Ex.) is hex value, and "H" is unnecessary during preparing real frame.
2) Device data type of each must be same. If data type of the first block is WORD, and the second block is
BIT, error occurs.
(3) Response format (ACK response)
Station
Format name Header
No.
Ex. of frame ACK H20
ASCII value H06 H3230
Item
When command is lowercase(r), only one lower byte of the value resulted by adding 1 Byte
BCC each to ASCII values from ACK to ETX is converted into ASCII and added to BCC, and
sent.
Number of data means byte number of hex type, and is converted into ASCII. This number
is determined according to data type(X,W) included in device name of computer request
Format.
Number of data Number of data in accordance with its data type is as follows:
• In data area, there are the values of hex data converted to ASCII code saved.
Data
Ex.1
The fact that number of data is H04(ASCII code value:H3034) means that there is hex data of 4 bytes in data .
Hex data of 4 bytes is converted into ASCII code in data.
