Description Item
If a GRESIII board is used, you must set the baud rate for the serial
port to 9600.
Channels: Specifies the number of temperature controllers on that
will share the serial port. For example, a Model 409 Temperature
controller may contain multiple Eurotherm temperature controllers
that all share the same serial port.
For FTIIm Systems–The maximum number of temperature controllers
that can be supported is 16, four on each of the four GRES ports.
Since RSCs must be on an interlock chain numerically equal to their
port number (Intlk 1 = Port 1, etc.), a station on interlock X will not
be able to use an RSC if there is a temperature controller on port X.
Name: Describes this resource as it will appear in Station Builder
resource lists when opened against an .hwi file. Analog Output icon
Changing this name may invalidate existing station configurations.
Address: Not applicable.
How to Add Temperature Controllers
Before you can add temperature controllers, you must add a GRES III board or 494.47 Dual
UART/Encoder mezzanine card.
1. Select Controller in the tree view pane.
2. Click the Miscellaneous tab.
3. Specify the number of temperature controllers.
Each temperature controller is associated with a specific Serial Port. Up to four temperature
control channels may be specified per temperature controller (Serial Port).
4. Select the correct Serial Port on the Temperature Control Properties tab.
Important:
If a GRESIII board is used, you must set the baud rate for the serial port to 9600.
5. Optional—define default temperature.
Set the Use Interlock Temperature field to True.
Enter the Interlock Temperature. This temperature will be sent to the temperature controller
whenever the station is interlocked or not loaded.
6. In the Com Timeout Delay field, enter the amount of time in seconds to wait for a communication
time-out with a temperature controller before reporting an error.
7. Select the number of temperature control Channels on the Temperature Control tab. Up to four
channels may be specified per temperature controller.
