CMR2020 to CMR2020 Communication

Product:             LOGO! CMR2020

Reference:           CMR2020 - CMR2020 Communication

Description:

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Two (2) CMR2020 located 1km apart. Each CMR2020 comes with Logo! 24RCE.

The first CMR2020 (with Logo! BM) is connected to two (2) pumps while the other is connected to a level transmitter on a Water Tower.

This is what I want to happen:

1. At location 1 (Pumping station), Pump turns "ON" supplying water to fill the Water Tower.

2. When the Water Tower is at "High Level" as sensed by the Level Transmitter, the CMR2020 will send an "OFF" command to the CMR2020 at the Pumping Station making the Pump to stop.

3. When the Water Tank level is at "Low Level" as sensed by the Level Transmitter, the same CMR2020 will send an "ON" command to the CMR2020 at the Pumping Station.

4. The cycle goes on until a manual shutdown or a "SHUTOFF" text command will be send to the CMR2020 at Pumping Station.

Please let me know if this is possible.

Looking forward to hear from you.
