IO Link

[TheWabit]

Hello

 

Changed PLM - Did it EXACTLY as the instructions indicated. Everything on the ISY looks fine and works except 1 IO Link. I have removed it from the ISY and when trying to re-add, it doesnt find it. I factory reset - same result. Any other ideas? It operats the item it is connected to when manually activating it.

 

Thanks!

The I/O Linc is power line only, no RF. You may have something on the same circuit that's interfering with communication. Is the I/O Linc in the garage? If not, where is it located?

[TheWabit]

It is located on on an outlet hi on the wall. It is used for the fireplace. Worked great for 2 years. When I changed the PLM, I got an error on that device - "cannot communicate with device xxxx"

It's not unlikely that you have added something (to that circuit) over 2 years. Adding or linking is a lot more intensive than using a device as is updating a PLM. One choice is to search that circuit and unplug or disconnect anything electronic (turning a device off is inadequate, it must be unplugged or disconnected). Even a wall wart can cause a problem.

 

Or you can remove the I/O Linc and try again on a different circuit, preferably on the same circuit as the PLM.

Thanks Stu - Let my try some of that.

So I have removed everything from that circuit. There was TV that I forgot about. But unplugging that gave me marginal success. I got error sometimes and other times not. I can only think at this point that it is failing.

[stusviews]

Just to be sure, plug the I/O Linc into another circuit (or use an extension cord to provide power from another circuit, ground in not required). Any improvement?

[TheWabit]

Crap! That worked great. So it is that orginal outlet. I dont know what the noise can be from. And why it worked flawlessly for 2 years. There is a CFL in that circuit. Could that be it? AND only after changing the PLM

[stusviews]

Yes, a CFL can certainly cause a communication problem. And, yes, changing a PLM causes every link to be rewritten to both the devices (where they must be) and to the ISY for a record.

[TheWabit]

So the CFL is not the problem. I removed it and got the same result. Based on your answer, can the links be completely removed and start over? I have factory reset the IO. I guess I still don't understand the updated PLM changes the comm problem. If I have a comm problem, it should have existed before - nothing has changed except a tv but after that was installed, it still worked flawlessly. Unfortunately - I am limited to this outlet because it is up on a fireplace and the low voltage wire goes across to the switch (on the inside of a drywall frame of a flume.

If you have a Lamplinc, a On/Off module or a Range Extender, which are all dual band, you can try plugging one into the IOlinc to see if that eliminates your problem. If it does then you most likely have a powerline communication issue that you'll need to work on.

Ok. How do you think a Filterlink will do if I can identify the problem device? I have never used one but I have one on the way.I wll try your suggestion - Thanks!

[stusviews]

The I/O Linc is power line only. Plugging a dual-band device into the I/O Linc pass-through outlet may help because if will add RF at a point very close to the I/O Linc.

 

A FilterLinc is only useful if the offending devices is plug-in. You may want to search again for something connected to the offending circuit. Solving the problem is considerably better than a work around, but in the end you may have no other choice.

 

Add the I/O Linc on a different circuit. Create all the scenes that you need, then relocate the I/O Linc to where it needs to be. That may be enough. If not, then there really is an offending device on the desired circuit.

[TheWabit]

Got it! Thanks. I will report back the results!

[TheWabit]

After much trial and error - I think I have it fixed. I have 2 offending devices on that circuit. That required me to buy 2 filterlincs. That pretty much solved the problem. I wish I could remove those items from the circuit but it just isn't possible. The only thing I am struggling with is my wireless remotelinc is not very reliable. I have to push the button 2, 3, and 4 times and move it around the room. Turning on the I/O with the admin panel works flawlessly. I suspect it is because I am still using the old 2440 remotelinc. And I do have a few dual-band devices in the same room. So I have never used filterlinc before - but it does work.
