2 Details of data items in message format
Data code during communication
Communication is performed in ASCII code.
(1) Block No, PLC No.
The block No. and PLC No. are ignored in a microcomputer connection of the GOT.
Specify "00".
"00" is converted to a 2-digit ASCII code (Hex) and transmitted from the upper digit.
(2) Station No.
Station No. is used to identify the GOT with which the host communicates. (Setting range: 0 to 31)
The data notated in decimal is converted to a 2-digit ASCII code (Hex) and transmitted from the
upper digit.
The GOT processes the command whose station No. matches to "Host Address (0 to 31)" set at
"Communication Detail Settings". (The message of command whose station No. does not match is
ignored.)
For setting method of "Communication Detail Settings", refer to the following.
Section 19.6.3 Setting communication interface (Communication settings)
(3) Command
