CHECKING ETHERNET CONNECTION
■ IP ADDRESS
The R7EWTU does not support BootP Table Software. The IP Address and Subnet Mask can be configured using the PMCFG
Configurator Software.
The Modbus/TCP Port No. is fixed at 502.
■ NODE ADDRESS
The R7EWTU firmware sets its Node Address to "01."
The Node Address (ID) is sent via Modbus together with data. Set "01" with the application software of the user.
■ CHECK WIRING
Connect an Ethernet cable to the RJ-45 connector.
■ CHECK LED
When wiring is correct, LINK LED is turned on with 10BASE or 100BASE link.
When the module is receiving data with 100BASE, LINK100 LED blinks.
