9.4 MELSECNET/H Utility
This section explains the operation of the MELSECNET/H utility.
The following are the precautions for use of the MELSECNET/H utility.
(1) Parameter details
Refer to the following manual for parameter details.
Q Corresponding MELSECNET/H Network System Reference Manual (PLC to
PLC network)
(2) Maximum number of concurrently applicable MELSECNET/H utilities
Up to 8 MELSECNET/H utilities can be activated and used at the same time.
(3) Precautions for writing parameters
Parameters written to the C Controller module become effective when the C
Controller module is powered off and then on or is reset.
(4) Precautions for connections from multiple MELSECNET/H utilities to the
same C Controller module
Connections can be made from multiple activated MELSECNET/H utilities to the
same C Controller module.
In this case, the MELSECNET/H utilities may have different parameters.
To make all of the MELSECNET/H utilities have the same parameters, read the
parameters from the C Controller module to each MELSECNET/H utility.
(5) Tabs available in offline mode
When the connection status of the MELSECNET/H utility is offline, only the items on
the <<Parameter setting>> and <<Target setting>> tabs can be set.
(6) Exiting Microsoft Windows
Do not terminate Microsoft Windows while the MELSECNET/H utility is running.
Exit Microsoft Windows after terminating the MELSECNET/H utility.
(7) Connection during script file execution
While script file processing is being executed (the RUN LED is flashing), access may
not be made from each utility to the C Controller module.
In such a case, connect each utility to the C Controller module after terminating the
script file processing.
Remark
For the functions added to the MELSECNET/H utility by version upgrade, refer to
Appendix 7.
