@tomas_hora,

I have one 1-wire temp -meter and 2 external I2C relay-cards (emorelay-boven and emorelay-beneden).
These relay-cards and the unipi card are supplied by separate adapters, so the grounds are not coupled.
Can this have influence on the speed?

if in the program 2 relays are switched at the same time (each relay on a separate relay card), i can see that they are switched one after the other. at least 0.5 sec after each other.

I would be nice if all relays could be switched in 100ms.

I use the older mervis runtime (version 2.5) on a Rasberry Pi B+, is the last runtime faster or is there no difference is speeds.

Kind regards,

Frans.

Got it, Thanks!
Shame on me!

Hello Thomas,

thanks for the quick answer.
Il try it this week.

Kind regards,

The time of how often your program is evaluated depends on the complexity of your program and of course on the performance of the HW. I have tested that a simple program like your on RPi 2 B is evaluated every 30ms.

You can do a small speedup by changing the sleep time between every loop - in order to do that you need to switch to your main Profile and then on the PLC change the sleep time parameter (default is 50%).
