Common Modbus Registers
F4T Mode
The following registers are applicable in the F4T Mode (Data Map 1). These are the most
common registers that would need to be used in an automation environment.
Some F4T parameters are contained within 32 bits (IEEE Float). Notice that only one (low order)
of the two registers is listed. By default, the low order word contains the two low bytes of the 32-
bit parameter. As an example, in the table below see Actual Chamber Temperature. Note that it
lists register 27586. Because this parameter is a float, it is actually represented by registers 27586
(low order bytes) and 27587 (high order bytes).
Parameter Name Register Data Type and Access (Read or Write)
Temperature Set Point 2782 IEEE Float RW
