Adding an ADI4 to a topology

Pee El Sea

Not sure if TIA does it automatically but you have to set up isochronous operation to get the ADI4 card to work and be accepted.

 I've set isochronous but nothing changes. The error is still the one attached. 

Hi

At this point I would normally point you to the release notes for your version, but as previously explained they do not make any mention of TIA (See attached).

Also with regards to V4.95 (SP2) please also be aware that some HMI based hardware restrictions came in when working with older generation hardware which you may want to consider if coming up from an old version (TCU.1 and HT8.1) see release below):

840Dsl will enter cancellation phase in October this year after which you will only be able to purchase hardware as spare parts, no longer for new installation / applications:

Hope this helps

I increased the BUS speed to the maximum permitted (12 mbps or baud i don't remember. Why there are so many choices?) and the problem was solved.

It was a bottleneck for the isochronous mode period (i needed 2 ms against the mimumum of 4 ms before the modification in TIA)

EDIT: i had to change the topology so i removed the ADI4 and restored the original speed of the bus.

Now i'd like to increase the BUS speed without adding ADI4 but I get error PLC sign of life monitoring, with the keyboard lamping. 

Why? it's quite annoying to change the hardware configuration，upload, do the reset PO and wait.

Here's the archive: https://1drv.ms/u/s!At-uuRTPt9bDkIMWUw2AO-Pj_u27vQ?e=ooexZJ

1. augmented the bus speed at 12 Mbps

2. augmented DP min speed at 2 ms (to resemble MD10050)

Not it works.
