Supported communication codes are JIS (ASCII) code and Binary (HEX) code. It is assumed that JIS
(ASCII) code is used to communicate with a computer, such as a PC, and Binary (HEX) code is used to
communicate with a microcomputer, such as a control instrument. Data is accessed with a
communication number.
* A bit is the minimum unit of information used in computers and expressed by 0 or 1. A group of 16
bits is called a word. In VF-AS3 communication function, this word unit is basically used to describe
the amount of data. A word can handle data of 0 to FFFFH in hexadecimal format (0 to 65535 in
decimal format).
