@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.

Re: Mervis reacting Slow

I have installed the mervis runtine on the Raspberri Pi. I used version 2.05 of the IDE and the runtime. This Raspberri is mounted on an UNIPI board and 2 extra relay-boards connected via the I2C bus.
The plc is running at 16.6 ms. the I2C enpoint is updated with 565 ms. It is almost the same as the one-wire temperature meter, 661 ms.
I tried different I2C speeds, There was no change in reaction time.
Is this End point speed normal? or must i use another runtime version?

I included pictures of the runtime status and the configuration.
All tips are welcome :)

Hello,

In the HMI software You can display values of different kind of variables.
There is a possibility to adjust a value with + and - keys.
Is i posible to type in a value?
I want to key in a time at which my lights switch on and of, so by means of a keyboard typing 11:05 for excample.

thanks in advance

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

Hello,

If i read the documentation well, the one wire thermometer is connected via an one-wire IC.
This IC is connected to the I2C-bus.

When i configure the I2C-bus, i can't chose the one-wire thermometer.

Does anyone know how to connect te one-wire thermometer and how to configure it in mervis?

Kind regards,

Hallo,

I have managed to get my Raspbery with the mervis software running.
I made a small program that reads and input and copy it to a relay output.
But the output is reacting very slow. About half a second to a second.
The mervis is running on a Raspberry Pi B.

any sugestions?

Kind regards,
