I believe the wiring is CN1 Pin 4 Status for “Job Running”, Pin 3 Out 1 for “Machine is Idle”, Pin 2 Out 2 for “Alarm”
The manual says “General output, with the function reserved.” My years in hardware/software educated me that when it says that, you can’t depend on it. Even if you measure it while in operation, it could have some strange function you are not aware of or that on the next firmware upgrade it won’t work anymore.
I’d love to be able to use a couple of extra outputs, but I couldn’t in good faith encourage others to use something that I’m really guessing at.
Out1 sounds like it’s a NOT(status)…
If you’re not guessing, then can we all know? NDA between you and Ruida?
The graphic looks a lot like one from a Ruida manual… is that it’s origin… that would be nice… that graphics not in any of my three manuals…
Kind of a tip off
there’s some Chinese thought behind it…
Do you suggest not using these outputs and using only the output with the name status?
If you want it to work for the product life, you can’t use anything that’s ‘reserved’ by the manufacturer. That term means they can use for and what they wish.
I suspect Lightburn has a better line into what these controller are capable of. The previous graphic probably came from China.
If it’s what Jeff stated, out1 is the inverted state of ‘status’ and some type of alarm for out2. What would you use these for? These machines are supposed to be ‘watched’ when they run because of potential dangers. If you are standing there and it has an error (or alarm) it will stop and display on the screen that it faulted. If it’s running, this is pretty intuitive.
Check out Davids link. I have a 6442G and don’t remember seeing that option.
I could see that in a room of them. Only in China…though.
You guys had tweaked my interest so I did a bit of digging:
We were hoping you’d explain it to us
I’ve been looking through these manuals. Most of the technical seems to contradict itself. One manual stated that it would drive 300ma, the other 500ma, same model. Some say reverse diodes are required, other do not.
Thanks I’ll also look…
Sorry Jack, posted the wrong link:
Not sure if this helps, found reference to these on the RDWorks Lab forum.
I know you mentioned this but I was thinking that the note at the bottom was a bit of a give away giving max current the OC can handle and that each can drive a 6V/24? relay. So should be OK for an LED.
What does that mean exactly? We know the kind of opto isolators on that board or not capable of more than about 20ma… So what does it mean to the user that they are opto isolated?
One of mine says similar but the current limit is 300ma.
All of these people testing it with leds…
My point here is the documentation that we all reference says it’s a "General output, with the function reserved.”, that means they can change it at will and don’t use it.
I would have thought that the General outputs are provided so that Vendors can add options to the machines that can be controlled by the controller or through software. Opto Isolation may not mean much at all to the average user and most likely those same users wouldn’t be looking to modify their machines in this sort of way anyway.
For those that do have knowledge/ability then the freedom to make a few mods is there, as it is with vendors who build the machines using these controllers.
To me General Output means they are provided for exactly this reason. Function reserved may of course mean they can change it at will but as these are inputs/outputs, any change at will would be for controlling something additional wouldn’t it?
It could be the Chinese way of saying for example that these General Outputs are actually reserved for a Stack Light function for those that are used in industry and a stack light is a requirement.
What if I ask this question directly to the company? What are the ways to contact them?
It should be simple, find a vendor that does this and ask them
Very probably its the stack lighting. Sounds like something they’d do…
I wouldn’t use them…
Good luck, take care
It’s true and configurable in the controller of a 6445. As far as whether a firmware update will change the signaling to those pins, consider that firmware updates place EVERYTHING about the controller in the hands of a manufacturer. (Don’t apply firmware updates for sport)
E.g, Ruida broke the wind signal.
Here is a post about a stack light being installed:
Also, these pins are used for other purposes. I use Pin 4 (Status) for fume extraction timed delay:
Status is also used in the ultimate air assist I believe. Those other Pins can be used for whatever you have the creativity and need for. How about a WOLO 330 “OOOOGA” horn for when the job is complete?
Brilliant, thanks for the information Jeff.
Thanks… My 6442 does not have the pictured options. What manual did that come from?
I do have an semi air assist working via status and wind sinks. Stayed away from the ‘reserved’ sinks.
That was a picture of my 6445 HMI taken with my phone specifically for that post. The schematic is for a 6442. The 6445 and 6442 work the same. They are essentially the same controller board. The differentiation is the HMI.
Although your 6442 HMI does not have those configuration options in the User Interface, you will find them available and accessible for configuration through Ruida’s RDWorks within the Soft PLC / Lamp Config:
Thanks so much… Don’t use windows so I’m not that failure with RDWorks. I did load it on my wifes Windows machine, but rarely use it. I will have to look, although I can’t really see a use for this under a ‘hobby’ situation. However some people like lights…
Thanks for the clarification, at least to this point.
