CHAPTER 8 TAG ADDRESSES
Tag addresses are used to identify parameters in the controller and are identical to the Modbus addresses which are also listed
in the Series 2000 Communications Manual, Eurotherm Part No. HA 026230. Tag addresses are used with the demand data
protcol to set up input/output data in the PLC or supervisory PC.. They are repeated here in the order in which they appear in
the GSD file.
They can also be read from the Windows Configurator by pointing to the parameter and clicking the right mouse button.
