I'm using the EA1-S6MLW display on a machine monitoring system and have noticed that the unit can not be programmed unless plugged into the PLC which in this case is a DL-06. I get an error saying that I'm using the wrong software version. I 've not tried loading a virgin screen but only one that I had previously loaded and then made a small change to. This could be a problem down the road if I need to change a screen and don't have a PLC around to plug it into. Firmware 2.20.00.00 Mask ROM V1.37

What is the software version that you are using to program it?

A screen capture of the error would be good too if you are seeing it on the PC. If it is on the panel, a snap shot of the screen would be good.

I don't believe this is the same error code I got last time but I reproduced this 5 times yesterday. Screenshot attached. I'm using version 2.20 Build 00.00.

I am curious how you got around these errors when they occurred. This error only occurs for the 3 reasons listed in the dialog. Did you find any of these to be the case when you saw the errors?

This error only occurs if I try to program the cmore when the communications cable to the PLC is unplugged. If I plug the cable back into the PLC and try again, all is well. I'm using port 2 on the cmore plugged into port 1 on the plc and then programming the cmore through port 1.
As I mentioned I'm creating 7 of these systems for all our plants. One plant actually needs 2 units and when working on the 2nd unit I made a change that I needed to apply to the first one. I pulled the cmore back out of the box, hooked up power and tried to upload the program. I got what I believe was another error but regardless found that if I connected this unit to the PLC, it would allow me to program it.
In addition, I'm using 2 USB to serial adapters simultaneously. 1 for the PLC and 1 for the cmore. It doesn't matter however if I remove one of them from the PC. It still will not program without being connected to the plc.

Wow this sounds like I had this problem awhile back. Did you check your cables. I am trying to remember, it has been a long time. I was using a wrong cable and was missing a ground or something like that. I know this is not too helpful, but I do remember I had this problem and it turned out to be the cable I was using.

This is usually a grounding issue. but the cable could certainly cause it too. Thanks for the feedback.

Cable it was. Thanks guys. When it works you just assume it's good. Not always the case...
