hello,

I'm looking for a small solution to control a door with a motor in order to open and close using SMS and also send an SMS when it is opened.

I see CMR2020 which has 2 digital inputs and two digital outputs and we can use SMS for send and receive. In my case, I will use 2 outputs and 1 input.

the P/N: 6GK7142-7BX00-0AX0.

My questions:

1- can the CMR 2020 can work as a standalone without need a LOGO BM "controller"?

2- If point 1 is valid; can we configure the CMR 2020 from the web or do we need a special software?

3- Can we customize the receiving SMS "for control open and close" code or syntax or there is a reserved syntax?

Thanks in advance

To 1.)
The CMR2020 can work independently without a logo.

To 2.)
It's kind of Web server on the CMR2020, with which you can configure the CMR.

To 3.)
To send or receive there is a special syntax. This is however explained in the Manual.

Here can you download the Manual.
