X20DO4529 configuration on X20BC0088 bus controler

Ask Questions Controls & Vision

Hi,

we have a problem on the X20DO4529 , once every few weeks we have one of the relay that goes OFF for any reason. We have changed the different module, changed 24V supply. but the problem stil comes back for time to time.

I ve read in the documentation that might come from:

  • Reset /warm start
    • restart that may put all DO to OFF
  • loss of communication
    • X2X goes off line / online and put DO to OFF
  • 24V micro cut
    • put all DO to OFF

I was wondering if it possible to fix it by software /parameter

  • Activating black out mode
  • changing beaviour on link failur / output behaviour to Hold last state

If yes, how can i do it ? i put the X20BC0088 to the last firmware , how can i access these configuration , do i need automation studio PRO? or can i do it with trial ?

Thanks in advance

Hello,

the “blackout" mode” is a setting of the buscontroller itself - not a setting of any IO module

Within “Modify configuration” you can only change settings of IO modules

Therefor this is no option

Your question is hard to answer as we do not know how the project was created.

Basically you use Automation Studio to create a new configuration for the buscontroller, its IO modules and all settings:

Here it is possible to set the behaviour in case of communication loss (blackout mode)

After compiling this project Automation Studio will create a EDS file to be imported for EthernetIP master and also a configuraiton file which can be downloaded to the BC0088 (via the webserver for example)

(As a sidenote an Automation Studio “PRO” does not exist - full or trial mode have basically no difference apart from the fact that trial mode is not allowed to be used for productive uses. As the name suggest it is supposed to be a trial)

To be honest I am unsure if you can switch the BC0088`s settings via the webinterface but I doubt it

If I would have to do this then I would used Automation Studio and the created EDS file

I forgot to mention that I think that this “blackout mode” might be dangerous to your machine.

If this (as an example) is the heating of your machine and you loose connection between PLC and BC0088 then the output will not switch off and your machine will most likely burn

Please keep this in mind

I would rather suggest to investigate why you loose outputs and fix this issue

Hello,

We investigated since 1year now , since the problem occur only every few weeks it’s very hard to replicate.

we know that :

  • The relay goes to Off without any command coming from M&C (we checked also the data from IP communication )
  • we have this configuration on 6 idencticals system and we have problem on only one
  • the 24V is a 10A driving only module and relays (so ok)
  • we changed modules and 24V

So remains , only cabling/ perturbation (EMC ) , X20BC0088 controler ….

Do you think :

  • doing an upgrade of the firmware might help (issue on the firmware of this module?)
  • i agree with you , black out mode may not be the best solution

What about the action of module failed / missing at power up/ module mismatch ? is there a parameter like : Hold Last state, no action/ or freeze?

I’m going to try again to access with automation studio, but yesterday i have error every time.

I’m still not able to see the configuration as your printscreen , still searching for the procedure on the wiki.

Which printscreen are you talking about ?

The first one of me is theintegrated webserver of the BC0088

The second one is not an “online” screenshot. It is a screenshot of the configuraiotn possibilities of Automation Studio when you create a project for the BC0088. This then results in an EDS file for the master PLC and a config file for the BC0088

Regarding your questions:

  1. I would anyhow do the firmware update as your BC does not show values in the webbrowser. As mentioned before this is due to the fact that the used “webengine” is too old for modern webbrowsers

If the issue is then gone is hard to say as I do not have the changelog of the firmware available

  1. Bascially the possibilitis you see in my second screenshot can be set on all of this options

Hello,

Sorry , i’m a beginner on this system,

I found the way to build the achitecture (AS 6 does not have the AR real time in the .exe) i had to install AS4

  • i’m going to try to download the configuration and check if other systems have the same configuration (which could (i hope) explain the difference of behaviour between system)

  • then i can try to avoid passing to off after (failure/lost of communication/ module NOK etc. , improve time of global action / RPI.

i found all of these that can improve the behaviour. (these relays only drive other relays , there is no power ^passing though them )

Paramètre Nouvelle valeur
Communication loss output Freeze outputs
Program mode output Freeze outputs
Module failed Freeze outputs
Missing at power-up No action
Global action delay 200 ms
Module init delay 3000–5000 ms
RPI 20 ms

Hope this will work

Thanks for the feedback and keep us updated if you like :slight_smile:

If you have any further question please let us know (no need to excuse if you are rather new to the B&R world)

An other question ,

I’m trying to connect online the X20BC0088 on my project and the goal is to be able to dowload the actual configuration on it .

Is that possible to do that ? is there an topic on it ?

I want to check all parameters on the 6 different system we have .

IP adress is 192.168.100.101 , ping ok , webserver ok . but still impossible to be online

Going online to a buscontroller is not possible (in terms of going online to a PLC)

You have the integrated webbrowser - thats basically all
