I've set my network settings to sysmac-way, , 7E2. When attempting to connect with the network config utility the activity LED does blink maybe times but the connection always fails. Any help to get this working is much appreciated!
Share this post Link to post Share on other sites. Later PLCs were bps. You indicated that you were using the 'network configuration utility'. I don't remember off hand what the lowest baud rate that auto-online would use. A few other questions. Is the PLC functioning normally? Which power supply are you using for the CQM1. Good call, PMCR! Auto baudrate starts at That's why auto-online didn't work.
Thank you wise sage. PA did not. Still no luck with those settings PMCR. I have CX-one v1. Could it be that the peripheral port has been configured for something no standard? Also currently there is no lights illuminated on my cpu, although the com1 light does blink on occasion when attempting to connect.
I have seen a couple of times on CQM1 battery leaked and destroyed the card near the peripheral port. Then communication was not possible. Under network settings, have you chosen network 0, node 0? Also did you try baud as suggested by PMCR? Checked the battery and the inside of the CPU. Nothing is leaking and all the boards look good.
I have tried both the peripheral port and rs port at baud. I may try and make an omron specific rs cable tomorrow to see if I can connect that way as the standard rs cable doesn't work. Network and node both default to 0 and I cannot change that setting grayed out.
If you are going to make an RS cable, use the document below. Remember that Signal Ground is pin 9 on the Omron serial port. OK, now we are looking for a deeper issue. In a post farther up the page, you stated 'Also currently there is no lights illuminated on my cpu, although the com1 light does blink on occasion when attempting to connect'.
When you say no lights, do you mean no RUN light? Is the PLC functioning normally, and only failing to communicate, or are there other problems that are causing you to try to connect? I would move switch 5 to the right OFF and then back to the right ON to make certain that it is making connection. I have seen some switches not fully seated in the ON position. I was using one last week, and had some difficulty fully seating it. Is the end cover properly attached?
