1.
Open the "IP Communication Test" window. Enter the IP address of the CPU module 2 or the local station (station No.2)
connected to the request destination device in "Communication Target". When the module that is connected to the
request destination device is an Ethernet adapter module, enter the IP address of the request destination device in
"Communication Target".

2.
Click on the [Execute Test] button to execute the test. When the test is completed, the route to the device set in
"Communication Target" is displayed on the underside of the window. If the test fails, click the [Details] button in the
"Error Information" area to check the error information.
• If the cause cannot be identified from the error information after the IP communication test is executed, or
communications cannot be performed even though the IP communication test is normally completed, follow
the troubleshooting instructions and take corrective actions. (
Page 253 When IP communications
cannot be performed using the IP packet transfer function)
• Up to 127 levels of modules can be connected when the IP communication test is executed.
• When an Ethernet device (request destination device) is connected to an Ethernet-equipped module, the
communication path to a master/local module, remote head module, or the Ethernet-equipped module
connected to the Ethernet device (request destination device) can be checked using the IP communication
test. Setting the IP address of the Ethernet device in "Communication Target" on the "IP Communication
Test" window causes an error. (Error code of the CPU module: 4A2AH)
• When an Ethernet device (request destination device) is connected to an Ethernet adapter module, the
communication path to the Ethernet device (request destination device) can be checked using the IP
communication test. For the IP communication test performed from an Ethernet adapter module, refer to the
manual for the Ethernet adapter module.
Precautions
Communications cannot be performed via modules that do not support the IP packet transfer function such as MELSECNET/
H. Only an error code appears without any information displayed in "Error Information".
