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 controller beyond the published amount of
registers, the EMS PRO controller will ignore the message as an invalid query.
