Powerful Solutions for Digital Plants

To assign a Dataset and a register in the Dataset to an I/O module, follow these steps:

1.Double click the IO_IN/IO_OUT parameter for the module. This brings up the IO_IN/IO_OUT Property window.

2.Click on the Browse button. This brings up the Browse window.

3.Click on the Object_Type drop down list, select All. This displays all the Dataset tags.

4.Double click on the desired Dataset tag. This assigns the tag to the module and closes the Browse window.

5.Choose the desired register in the Parameter drop down list.

6.Click the OK button.

For output modules, user also needs to change the MODE parameter to Manual for Normal Mode and Target.

5.5Using Diagnostics

Verify PSIC communication: Select the PSIC on Diagnostics and press the right mouse button. Select Display Real -Time Statistics from the drop down menu. If the Programmable Serial Interface Card is functioning then the user will see the Valid Responses counter and the Async and/or Sync Transactions counters incrementing. There will not be any error counting up. This method checks the railbus communications between the serial card and the DeltaV controller.

Verify port statistics: Select the Port on the Programmable Serial Interface Card and press the right mouse button. Then select Display Port Statistics form the drop down menu. Verify that the port communications statistics are being displayed properly and are counting as expected for the Allen-Bradley protocol’s functionality.

Verify Dataset values: Select a Dataset and press the right mouse button. Select View Dataset Registers from the Drop down window. Verify that the Dataset values are displayed as expected.

5.6LED Indication

The Yellow LED for the port should be on solid when all communications on that port are valid. The Yellow LED should be blinking if there is some valid communications and some communications with errors on that port. The Yellow LED should be OFF if there are no valid communications on that port.
