Integrating Tstat10 with Arduino/Raspberry Pi

Tstat10

  1. Will it be possible to setup Tstat10 as a Modbus slave, for making it to communicate with Arduino or Raspberry Pi? Any prior experiences?
  2. Can we create Alarm objects in Tstat10 and expose the same over Modbus?

We are trying to generate SMS through Arduino/Raspberry Pi based on an Alarm, generated within the Tstat10…

Hi Max,

Yes … lots of experience with T10 and other TCO controllers using Modbus (serial and tcp) via Node-Red and Raspberry Pi . So much so that I authored an instruction course here … And for the next 30 days there is a ~10% discount for all Temco users who use the above URL link.

The course uses a modbus sensor rather than a tco unit but the modbus setup is exactly the same on our other tco projects. The course also shows how to setup email alarms but not sms unfortunately.

enjoy!

  1. Modbus Slave, just set the com port on the RS485 port to Modbus mode. Depending on your version you may not see Master and Slave here, the device can automatically switch from master to slave and back.

  1. Alarms:
    A program will watch a current sensor on a fan for example and compare it to a trip point. If the current is over the trip for more than a few seconds trigger the alarm.

10 IF FANAMPS > FANTRIP THEN START FANHIAMP ELSE STOP FANHIAMP
20 IF TIME-ON( FANHIAMP ) > 0:0:10 THEN START FANALARM

You will poll FANALRM and do some actions when it triggers. In your Pi UI you will let the operator reset the FANALARM variable manually.
