How to use Clock function on Solo Controller for multiple setpoints using Click PLC
I was asked to add a clock function to a solo 4848 controller so that it heats a tank of water to 140F at 7am and cools to 110F at 5pm to reduce evaporation at night then reheat in morning, is there a way to use the 485 connection to send these two setpoints to a solo controller using the clock and calendar function, I would also like to ask if I can use a single click plc to send the setpoints to multiple solo controllers. Components in use, Solo SL4848R, Click PLC C0-11DD1E-D, and Headless HMI EA9-RHMI
That shouldn't be any problem. If each SOLO is given a unique ID, then a large number could be controlled over RS485 by one CLICK. One thing to be careful about; when the set point is changed on a SOLO it writes to the EEPROM, and EEPROMs have a finite write endurance (maybe 100,000 times) if you are changing only twice a day that would be over 100 years so no problem. But be sure your code writes to the drive only once each time you make a change, a coding error that wrote multiple times, or worse case, continuously, could kill the SOLO quite quickly.
thanks the supervisor is wanting me to control 8 solo controllers, is there anyway you can help me write a program for this, every controller is set to the same temperature
Hi @shanem717 (Customer)
The following post will show you how to communicate with the Solo from the Click PLC.

I hope this helps you out.
