Chapter 3: Quick Start Guide
A simple system is setup to demonstrate messaging. The simple system consists of a 1756-DNB, the MSR312P, and a
PanelView 1000.
Example 1
Using Change Of State (COS) messaging, the Input Module Values 1…8, the Y34 Output and the System Status will be
displayed on the PanelView 1000. This information is located in Option 6 (165) of Parameter Input Assembly (COS).
Step 1. Select "165: 8 inputs and 1 output" (Safety Input 1a-4b with Status Y34 (2 bytes))
In the RSNetWorx Graph tab, double click on the MSR312P icon. Click on the Parameters tab, and scroll down to
Parameter 104. Click on the “Current Value” cell for Parameter Input Assembly (COS), and the drop down menu will
automatically appear. Select the desired option (in this case, 167). If you click on the “parameter help” icon, it will state the
number of input and output bytes required for each choice. This will be needed in the next step. Notice it states 2 bytes IN,
1 byte OUT. Click OK. This determines the data that will be sent to the 1756-DNB scanner via the COS connection.
