10-2 Echoback Test between Nodes
10-2-1 Overview
The Internode Echoback Test between PLC Nodes tool is used to execute echoback
tests between specified networks and nodes and the CX-Integrator. Echoback tests
can be executed for Ethernet, Controller Link, SYSMAC LINK, or DeviceNet networks.
A specified data length (unit: bytes) is sent to a specified network and node. The data
is sent back as is (echoback), and the results are compared. If the data agrees, it is
judged a success. If not, it is judged a failure. This allows the communications load
conditions between the computer and specified nodes to be tested.
