Data Items for Protocols
•
Transmission control code: 1 byte
•
V7 port number: 2 bytes
Port numbers are used so that the host computer can identify each V7 series for access.
The data range is from 01H to 1FH (1 to 31) and is converted into the ASCII code before use.
The port number of the V7 series should be set on the V-SFT editor. (Refer to “V-SFT Setting.”)
•
Command: 2 bytes
Available commands are shown below.
•
The number of words to be read or written: 2 bytes
Set the number of words to be read or written by one command.
The data range is from 01H to FFH (1 to 255) and is converted into the ASCII code before use.
•
Memory address to be read or written: 18 bytes
Specify the memory address to be accessed.
Set the following code in the format as shown for “Read target memory setting” on page App7-5
and “Write target memory setting” on page App7-6.

PLC memory
Depends on the PLC to be used. Set the type number indicated for “Available
Memory” of respective PLCs on “Chapter 2” to “Chapter 33.”
Temperature control/
PLC2 memory
Depends on the PLC to be connected to the temperature controller and PLC2
function. Set the type number indicated for “Available Memory” of respective
temperature controllers on the Temperature Control Network Manual. Set the
type number indicated for “Available Memory” of respective PLCs on “Chapter 2”
to “Chapter 33” when using the PLC2Way function.
