Supervisor table
7. SUPERVISOR TABLE
Chiller provides a database of supervisor variables via Modbus RTU protocol over RS485 (BMS port on the Chiller controller).
The BMS port has the following default settings:
• baud rate 115,200;
• data bits 8;
• no parity;
• stop bits 1.
See "Parameter table: BMS port" to set diff erent values.
"Index" is the address specifi ed in the Modbus® frame.
