QJ71E71 Ethernet IF module

2 posts in this topic

Does anyone have experience from this module ? We have problems reestablishing communication after forcing a disconnection. Sometimes it works and sometimes we have to poweroff and poweron manually. What could be wrong ?

I had quite a few problems when using this system a while ago. I could communicate over ethernet using GX developer and the PLC's would not communicate with each other, OR I could not communicate over ethernet using GX developer and the PLC's would communicate with each other. Never both together In order for the PLC's to communicate, the system must be changed from Automatic repsonse system to IP address computation system AND the IP address of the computer must be included. As for the Power on/off, can you not toggle Y19 (initial request) in order to get the card to reset?
