What are the best PLC's for HVAC automation? Are they affordable (less than $1000) and have a good cost/benefit ratio? Is it possible to establish communication between a custom PC application for monitoring and the controller using a standard RS-232 cable?
 
Hi,

Why dont you try out honeywell controllers (like XL500, XL-100 etc.. depending on your application), they are specially designed for HVAC applications.. and now you need not worry for the proprietary software or accessories as these controllers support open standards (LON).
 
S
Many different PLC types will do the job but be sure to check what elements of the HVAC you want to control/monitor.

Within the UK operation of schneider we have used both the low end TWIDO PLC and the top of the range Quantum.

We would need more info to better ascertain the specified PLC.

Please drop me a line at [email protected] or sam_thiara on this matter if problems exist.
