Hi everyone, We really appreciate how we can use generic software modules in B&R Automation Studio’s LogicalView and map variables to different hardware configurations without impacting the source code of our POUs. Now, we’d like to incorporate IO-Link sensor/actuator hubs for digital signals usin…

Unfortunately that’s the tradeoff between specificity and customizability; there are pros and cons to both. It’s just my opinion, but I think that your first option (Dedicated Task + PV Mappings) would be easier to maintain in the long run. You can map an input to multiple PVs, but as you said mapp…

Hello Stefan, Please have a look at this post which shows an example of how to handle Boolean data points in IO-Link. Providing valve control with the X20DS438A module ! Regards Stephan

Hi Stephan, Thanks for sharing the link, but I’m afraid it only addresses the simpler aspect. Setting a bit in an integer isn’t really the challenge I’m facing. The example you provided does, however, illustrate my main concerns: With the octet-array approach you loose the ability to force one o…

Thank you for your insights. Since we’re using AppModules, we also keep IOs locally, each with its own *.iom file. We’ll likely move forward with the IO-handling-Task approach you suggested and aim to maintain usability for the commissioning team, who primarily rely on the physical view.

I have actually used IFM IO-Link masters (model AL1122) as well as the B&R X67DS438A. The main drawback with the B&R unit is it can’t handle 32 byte PD. It is only capable of 29 bytes (if I remember correctly). This was a huge problem when using a Banner IO-Link smartlight, as the mode selection was…

Hi, I came across your thread about the issue with the Banner LED strip. We encountered a similar problem with a 7-segment display (Captron Caneo) but managed to get it working by using multiplexed Octet Arrays on the DS438A. I also had the IFM Master on my desk, as we were testing its capabilitie…

I believe you can, but only with the following part numbers - AL1370 & AL1372. I used the EIP version (AL1122) with an X20IF10D1-1 as an EIP master. I had a bunch of other wireless IO I needed to communicate with using Ubiquiti P2P. I did play around with the Powerlink version in a sample project, b…

Yes, we had the AL version on site. As for EIP, I believe the new Balluff multi-protocol master is a strong contender. It’s a pity they don’t offer Powerlink. https://www.balluff.com/en-de/products/BNI00K6
