- 14 -
- For the available PMC area:
- If the PMC’s type is PMC-SD7, the available PMC area
is %M, %ME, or %R.
- If the PMC’s type is PMC-SB7, the available PMC area is R, E,
or D.
Server design of MODBUS/TCP function
The Server design of FANUC MODBUS/TCP function is shown in
the following.
- “Automatic TCP connection management” is implemented. This
means that user application (such as Ladder program) does not
need to take care of TCP connection.
- “non-priority connection pool” is implemented. This means that
the oldest connection is closed when the requests from the
multiple clients are received and the connections are full, FANUC
MODBUS/TCP Server function can receive the requests from the
maximum 16 clients at the same time.
“priority connection pool” is not implemented.
- “Access control service” is not implemented. This means that all
of device can be accessed without authorization (user name, or
password).
