6.10.2 Loop back test (Communication using MC protocol)
The loop back test can be performed with communication using MC protocol in order to check the completion
status of initial processing for the target Ethernet adapter.
The following is an overview of the loop back test for communication using MC protocol.
For details, refer to Section 7.7.
1) Loop back test for communication using MC protocol
The loop back test is a function designed to check the following:
- Whether a line has been properly connected to the test target Ethernet adapter.
- Whether the parameters for the Ethernet adapter have been correctly set.
- Whether the initial processing for the Ethernet adapter has been completed normally.
- Whether the program for the external device is running correctly.
2) It is necessary to connect lines when performing communication using MC protocol with the user port on
the Ethernet adapter side.
Perform open processing for the connection to be used on the Ethernet adapter side.
3) This function can only be used for the Ethernet adapter of the local station. The function cannot be used
for the Ethernet adapter of another station via a network system.
6.11 Open Settings
This section explains open settings.
Open settings operation (establishing connection) with the external device can be performed to a maximum of
four stations.
Once a connection is established with an external device, it is possible to communicate using MELSOFT
connections and MC protocol.
For open settings operation of GX Works2, refer to Section 8.2.
