Communication Diagnostics for Mitsubishi Ethernet Driver Shows TX Only


Last Update: 2018/11/12

Problem:
The Communication Diagnostics for a channel using the Mitsubishi Ethernet driver shows TX (transmit) but not RX (receive).

Solution:
Ensure that the switches are set properly on the Mitsubishi A-Series Serial Card. For more information, refer to the DIP-switch diagrams located in the "A Series PLC Setup" topic in the Mitsubishi Ethernet Driver product manual. On the physical hardware, each switch actuator is shown by a white rectangle.
