Chapter 3 Configure Your Module Overview Configuration Overview This chapter describes how to configure your thermocouple input module with RSNetWorx.
18 Configure Your Module Using the RSNetWorx Commissioning Tool Use the RSNetWorx commissioning tool to commission devices (set the node address and the data rate parameters) that are: • connected to a DeviceNet network. • connected via a point-to-point connection. The node commissioning tool works through RSLinx; RSNetWorx does not have to be online when performing the operation. Before you can add any device to a DeviceNet network, it must be commissioned.
Configure Your Module 19 Use Sequential Auto Addressing Sequential Auto Addressing (SAA) reassigns the node address of every module to the right of the one you select. Each module changes its node address to one greater than its neighbor. IMPORTANT Make sure the node address of the selected module is the desired value before issuing the SAA command. When this command is set, each module to the right gets a new address one greater than its neighbor.
20 Configure Your Module This chapter shows configuration in the online mode. Configuration dialogs appear similar in both modes. The primary difference is that if you make changes offline, you must go online before the configuration changes take effect. Perform this procedure to add a communication device. 1. Start the RSNetWorx for DeviceNet software. 2. Add the communication adapter as shown in the figure. In this case, the chosen device was a 1770-KFD RS232 Interface.
Configure Your Module 21 The out-of-the-box node setting for 1734 modules is 63. You can change the setting by using the node commissioning tool. The node commissioning tool is available either online or offline. 1 2 1. Go to the Tools pull-down menu. 2. Select Node Commissioning. 3. Click Browse. 3 4. Select the module to change. 5.

Click Start Calibration, which is active when: • the system is online. • you selected at least one of the channels. Note that you can press the F1 button on your keyboard or click Help from the wizards and warning messages that appear to get detailed information about the procedures for calibration. If a Danger dialog appears, the module is not inhibited.
68 Configure Modules in RSLogix 5000 Software 8. From the High Value dialog, click Next to start calibration. The Calibration Completed dialog appears. It shows that you saved the changed calibration constants of the channel. 9. Click Finish to exit the wizard. The channels can now be configured for the sensor type desired for normal operation.
Appendix B Calculate Absolute Accuracy and Accuracy Drift Overview The Absolute Accuracy and Accuracy Drift with temperature specification applies only to mV input for 1734-IT2I, and to ohms input for 1734-IR2 and 1734-IR2E modules. These specifications are listed in the POINT I/O RTD and Isolated Thermocouple Input Module Installation Instructions, publication 1734-IN011.
70 Calculate Absolute Accuracy and Accuracy Drift Full Scale Values Use the following full scale values to calculate the formula: Full Scale Values Module Full Scale Value 1734-IT2I 160 mV 1734-IR2 625 Ω 1734-IR2E 157 Ω To find out the Absolute Accuracy or Drift in degree Celsius, you can consult a conversion table.
