61.1 Microcomputer Connection (Serial)
The "microcomputer connection (Serial)" is a function by
which data can be written or read from a PC,
microcomputer board, PLC, etc. (hereinafter referred to as
"host") to virtual devices of the GOT.
Interrupt output is also available from the GOT to the host.
POINT POINT POINT
Virtual devices inside the GOT
The devices inside the GOT are used in the
microcomputer connection.
(PLC devices are not used.)
61.4 Device Data Area

Flow of data processing
(1) When reading or writing data
1.
The host sends a request message (the read/write
command) to the GOT.
2.
The GOT performs a read/write processing to its
virtual devices according to the request from the host.
3.
Upon completion of the processing, the GOT sends a
response message (processing result) to the host.
4.
Creating the following objects on the screen allows
you to use the data read/written to the virtual devices:
• Numerical Display that displays data written by the
write command
• Numerical Input that is used to input data to be
upload to the host
