Description 

The 

EMS PRO LITE

 implements a MODBUS RTU style communications 

protocol. The following describes the communications, and the register 
and coil implementation for the 

EMS PRO LITE

. 

 

Protocol 

The 

EMS PRO LITE

 controller will reply to MODBUS RTU 

communications. This communications protocol uses RS232 or RS485 
standards set to 9600-baud rate, no parity, eight (8) bits and one (1) stop 
bit.  

•

 

MODBUS® function code 03 - Read Holding Register 
Status: Reads the binary contents of the holding 
register in the 

EMS PRO LITE

 controller. 

•

 

MODBUS® function code 06 - Preset Single Register: 
Presets a value into a single holding register. 

•

 

MODBUS® function code 16 - Preset Multiple 
Registers: Presets values in a sequence of holding 
registers. 

Registers 

Registers are adjustable or varying data locations within the controller 
whose value is an integer value not just ON or OFF. They can represent 
the system analog input for flow or pressure. The registers could be an 
adjustable system parameter such as delay on start. The following is a 
list of the registers that can be accessed. The maximum number of 
registers that can be read at one time is 125. The starting address of the 
registers is 40001. 

 

NOTE:  If a query is made to the 

EMS PRO LITE

 controller 

beyond the published amount of registers, the 

EMS PRO LITE

 

controller ignores the message as an invalid query.
