Dear Joel

since my last post I did some experimenting and I discovered that the delay is actually from Mango.

what I did was I have a DGBox that I had before, I disconnected Mango from the Bacnet MS/TP network and connected the DGBox, I also Disconnected the Johnson controller. the DGBox discovred the devices quickly, I added the devices and the speed was amazing, as soon as you turn on a datapoint it happens instantly.

any thoughts on that.

At this point the Johnson is doing the timing and helping with the discovery of the Backnet ms/tp units. my problem is that when I remove the Johnson controller from the network Mango is unable to control or send commands to them through bacnet ms/tp. my suspesion is that Mango MS/tp protocol is not able to give the right timing and speed of the serial to the units. but when the johnson put back in the network every runs fine.

now I have a small delay in response time from the bacnet units the delay is between 4-9 sec and I'm suspecting the Johnson controller is causing it. since I have Bacnet TCP running with no problems I thought I would install a bacnet ms/tp to bacnet tcp converter and have the mango on the TCP side to see if the delay problem can be resolved.

Hi

I did have problems with Bacnet MS/TP, the only way I could do discovery or proper polling is through a Johnson controller or .
But I have an idea that may work and will let you know soon, I'm going to get a Bacnet TCP to Bacnet MS/tp and try it that way.

I would be very interested in implementing Z-Wave on mango, any one can help?

OK since my last post this is what I did.

I checked all the devices for termination and made sure that all of them have no termination except the first and the last.

I changed the USB->RS485 dongle and placed it on a different USB port that doesn't have any devices connected to it.

the result is that the delay has dropped to 4-9 secs for response. (Still a bit long)
the pooling error has Stopped
the problem with the devices being seen by mango but not responding has stooped.

discovery is still an issue. ( I really need help with that since I need to put a $1000 controller to see the devices)

I need help with the delay.

this is what I got

as for the other problem, it was suppose to fixed with the Bacnet module upgrade. but it wasn't>.

I have no idea where to find this matrix..

having said that I increased the timeout on the Bacnet serial configuration and it seems to have solved it. I did find a mis-configuration on the devices and I solved it the delays are still there but a little lower now. I'm getting between 5 - 10 seconds delay between action and physical reaction.

I still think that you should go into the server and see if I made any mistakes that is causing this problem.

also the problem of device discovery still exists, the only way I can do discover is to put a Johnson controller on the serial network. I think it's a problem with devices they need to get the serial configuration from Mango, and Mango is not giving them that.

OK here is something new, I'm getting this error alot:

Lights_Fire': Data source with xid: DS_Lights_FireCom3 and name: Lights_Fire, aborted 12 polls.

and the number keeps increasing...

any thoughts?

Hi Joel

No errors when the devices stop responding. As I said Mango seems to think that the devices are responding I did however noticed that when you turn on / off relay a couple of times it sort of starts turning on and off erratically after a long delay.
As for the thread pool I got the error a while back and I increased it to 1000.
I have 12 devices each with 21 data points and all the data points are in the same data source.
The pooling period is 1 second.

Hi

I have a Mango system that is growing with the specs are as follows:-

• Xeon E3 1.6GHz Server with 20 GB RAM
• Linux Centos 6.7 64 bit
• Mango Enterprise
• 6x USB to RS485 Dongles
• 2x 1Gb Ethernet

I'm using the following protocols:-

• ModBus I/P
• ModBus RTU Serial
• BacNet I/P
• BacNet MS/TP Serial

as I built the system I was only using ModBus, then I introduced BacNet Devices to it, at first BacNet I/P then BacNet MS/TP, when I started using BacNet MS/TP problems started:-

• first the BacNet device where not being discovered, I added a Johnson controller which solved the problem temporarily then an Upgrade for BacNet MS/TP was done by Mango but the problem still persists to this day, if I remove the Johnson Controller the devices stop working. when the upgrade was done I could do manual discovery but now I can't.
• as I added more BacNet devices a delay started occurring, for example:- I have a device with Digital Input and Digital Output, I use a sensor connected to the DI for On/Off when it is On then DO is turned on by Mango when it is Off mango turns off DO. at first the delay was about 2-5 seconds which was acceptable at the beginning there were about 8 devices connected to the RS485 with less than 60 meters of cable (I used CAT6A shielded), as I added more devices the delay started to increase between sensing and turning on, now with 12 devices connected the delay is about 20-30 seconds.
• another problem occurred when I added more devices to the system (14), every about 5 hours a strange thing happens, the devices are seen by Mango and I can control them through DGLux and Mango, but physically nothing happens. I can turn a relay on and off but the light stays either on or off depending on it's last state. the way to solve this is to turn off the Data source and then turn it on again, then things run again, but after 5 hours the same thing happens. the only way to fix it is to remove the 2 new devices.
  so I though OK I can add another RS485 and split the devices then it occurred to me that I cannot discover the devices unless I have a BacNet controller with them, which I don't have. and if I remove the Johnson controller and put it on the other network then I lose control on the first.

I really need help with this issue, I can grant access to it so you can check things out.
