Is Visio a programming tool or just a front end software?
Many points can be changed from the jace but in my opinion a true automatic control system doesn't have to be manned or it would be called a manual control system. Once the characteristics of the building are figured out you make adjustment to the program and leave it alone. If it has to be manned then it wasn't done right in the first place.If you are not an Alerton rep you cannot get the software, however an end user/facility can possibly get it. There are a few hoops that one has to jump through as told to me by a friend who manages a building with an Alerton system. Is the Jace being installed by the original installer of the Alerton system? Is there any documentation about the installation? Is Visio a programming tool or just a front end software?

If it has to be manned then it wasn't done right in the first place.I believe Alerton uses Visio as the base software with their own program and plug-ins loaded overtop of it. Essentially, the engineering environment is two programs bundled together/ As whatnoise indicated, for a non-Alerton dealer to obtain software is very difficult - you'll find this is common with most control manufacturers in the industry. You are correct that a properly engineered control system should not require manual operation to work - then again, if it met the original specification. The best way to program the stuff is to get a copy of Alerton Envision for Bactalk and Microsoft Visio.
That way you can use visuallogic. The interface for Visuallogic is graphic based. My avatar is an example of what it looks like.
If you're strapped for cash and don't want to buy visio, programming can also be done via the 'bluescreen' through Envision by selecting 'tools', 'ddc', and 'VLC'. That's a text based editor and I wouldn't recommend it for someone who is new to Alerton. Personally I much prefer using Visuallogic. It makes the code much easier to understand.
If you want programming details, Alerton's programming manual (LTBT-TM-PRGRMR) will get you started. Now here's the hard part.
It's very likely that these controllers have an Alerton Global Controller passing points between them and doing schedules. If this is the case, then you have to either leave the global controller in to pass points, but remove all the schedules and let the jace handle that, or you can remove the global controller. If you decide to do the latter, you need to really read into what the global controller's code is passing between the controllers and try to get the jace to emulate that, which is no easy task. If you are using an R2 jace, the setpoints can be tricky if you want to be able to change them from the Jace's web interface but don't want to remove the user's ability to change the room setpoint at the Microset.
I have a little DDC sequence that can get around that if you need it. If it's AX, don't worry about it. Just keep in mind that in the old C3 controllers, there is no priority array for the occupied schedule command (BV-40), and some of the newer functions like RED, WED, REDS, and WEDS are not supported. Also if you decide to edit code, make sure you leave the outputs 'out of service' as the old C3's sometimes had comm issues that caused the outputs to go overridden for no apparent reason, especially if a jace is involved. Otherwise, like misternorth79 said, the system shouldn't require a manual when properly engineered, assuming the interface is intuitive.
Last edited by beardenbc; at 01:20 PM. When the customer bought the building there was a half a$$ front end on site it has a dongle. The jace installer had to put visio on it to find points? Is the engineering tool 'envision' usually packaged with the front end software so maybe it is on the computer or would that not be likely? When I pulled up visio it had control icons but no connections where shown, when I clicked on the controller icon it brought up i/o point options. Is this the programming software? If so can controllers be donloaded and uploaded from this computer.

It's used in conjunction with Envision to give you visuallogic. Visuallogic is really just a macro for visio that is included with Envision. Now, about envision.
It's just the basic interface that Alerton uses to interface with a bacnet control network. It's your user interface. You can also do programming through it. It is probably installed on the PC part of the front end if they have one. Now, when you pull code out of controller and into visuallogic, you probably aren't going to have all the connections shown. The reason is that the controllers don't have enough space to store the data involved with the graphics, so you'll have to manually connect them.
Now, one thing you can do instead is open the device manager and look to see what ddc is in each controller on the network. From there, you can open the original version with all the points listed so that you can better see what is going on in the code. It's in the folder under something like c: program filesAlerton bactalk.rep.job. ddc. There should be some visio files in there with all the geometry for the lines and points still in there.

When you clicked on the controller, you pulled up the basic I/O options for that code, so you're good there. You're in the right place. When you alter the code to your liking, click on visualogic/options/ddc save options and ddc send options and make sure you remove geometry.

To send the ddc to the controller, select visuallogic/file/send ddc to device and select the device instance and you can send it straight there. It sounds like you have everything you need.
I have a building that has both Delta and some Alerton controllers (most and the LSI have been removed). I can monitor and control the points on most of the Alerton controllers but in a couple the points are marked out of service and can't be manipulated. Would this be a manual override through the Alerton? And if so can it be released without the Alerton software?
I'm assuming this would have a higher priority then what any BACnet system could send. Could the module be formatted? I was only looking to monitor a couple of points from it? I have a building that has both Delta and some Alerton controllers (most and the LSI have been removed).

I was only looking to monitor a couple of points from it?If a point is marked 'out of service' this should only apply to AO's and BO's. To put them back into service, yes, you will need Envision.
It can be done either from the bluescreen I mentioned earlier or through visuallogic, because the lockout lies in the DDC code. Thanks Beardenbc, that’s what I was afraid of. This Envision software, Is it possible to get a copy of it? I see in a previous thread VisualLogic was said to be restricted.
Is it restricted by hardware key? I have a BACtalk key and access to the original PC the site software was loaded on, would I be able to get what I need from the old computer? How would you connect to the modules?
Through a 485 converter? Would you have any literature that might help with some questions? I do have Viso. Envision is the restricted software, but it's restricted only through hardware key, so if you have access to the old computer, you have access to it's hardware key too.
Visuallogic is just a visio macro that comes with Envision. The only hard part will be coming up with an Envision install CD. So, really, you already have everything you need, kinda. With your new computer you connect the same way the old one did, through the old global controller via ethernet.
Make sure you have the bacnet protocol installed on your ethernet card. From there you start up envision, go to 'general system setup' or something to that effect, select the network tab, and select your ethernet card. I'd like to help more, unfortunately, I'm not at my office where all my docs are again until monday. I'll be able to dig up some more details then. Last edited by beardenbc; at 11:30 AM.

I'm looking at VAVi-SDs and 853s to name a few. If an VLC-853 controller fails, and I install the replacement, can I download the existing programming from the BACtalk front end to the device? I'll be copying all dip switches, wiring up same as old unit. If I remember right, access to VLC DDC is needed to bring up that DOS looking window, and then send to DDC. I don't think this site has installer access, so the menu I'm used to seeing doesn't show up.
