Chapter 1 900-TC Temperature Controller Setup
Choose a Communication Port
The 900-TC temperature controller has two communication ports that operate independently:
• Unit No. 1 – a fixed 4-pin port
• Unit No. 00…99 – an RS-485 port on 900-TC16 controllers and an RS-232C port on 900-TC8 controllers
The communication parameters of the 900-TC16 controller must be set before any communication via Modbus protocol
can be established. You can set the parameters with the front panel of the temperature controller or by using the optional
900Builder Lite software, version 3.0, and the 900-CPOEM1 cable.
Set Communication Parameters
You must configure the temperature controller for Modbus communication so you can communicate between the
PanelView 800 terminal, Micro800 controller, and 900-TC temperature controller.
This section provides instructions on how to manually set the communication parameters through the front panel of the
temperature controller or by using the optional 900Builder Lite software, version 3.0, and the 900-CPOEM1 cable.
Set Communication Writing
Follow these steps to set the communication writing parameter to ON (OFF is default).
1. Press the key for less than one second to access the Adjustment function group display (B).
2. Press the key once to access the Autotuning (AT) parameter (C).
3. Press the key once to access the Communications Writing enable/disable parameter (D).
4. Press the or key to set the communication writing parameter to ON (E).
5. Press and hold the key for longer than one second to enable the change and to return to the Operation function
group display (A).
When communication writing is enabled (ON), the indicator on the front panel illuminates.
TIP
An RS-485 communication card must be installed in the controller to use RS-485 communication.
TIP
The easiest way to set parameters in an application that includes multiple 900-TC temperature controllers is to use 900Builder
Lite software, version 3.0, and the 900-CPOEM1 cable.
