Local Slave or Connection I/O Value Diagnostics

Introduction

Use the I/O Values page to display both the input data image and output data image for the selected local slave or scanner connection.

NOTE: Before you can open the diagnostics page, make the connection between the DTM and the target communication module.

Access the I/O Values information:

Step	Action
1	In the DTM Browser, find the name that is assigned to the CPU DTM.
2	Right-click the CPU DTM , and select Device menu > Diagnosis .
3	In the left pane of the Diagnosis window, select the CPU.
4	Select the I/O Values tab.

Use the Refresh Every 500ms checkbox to display the static or dynamic data:

Checkbox	Description
Selected	Display data that is dynamically updated every 500 ms. Increment the number at the top of the table each time data is refreshed.
De-selected	Display static data. Do not increment the number at the top of the table. That number now represents a constant value.

This page displays theses parameters for either a local slave or a remote device connection input and output values:

Length	The number of bytes in the input or output data image.
Status	The Scanner Diagnostic object’s status, with respect to the read of the input or output data image.
