Local Slave / Connection Diagnostics

Introduction

Use the Local Slave Diagnostic page and the Connection Diagnostic page to display the I/O status and production/consumption information for a selected local slave or connection.

NOTE:

Before you can open the diagnostics page, make the connection between the DTM for the target communication module and the CPU.
To get data from the primary CPU, make the connection to the Main IP address of the CPU.

Open the Page

Access the diagnostics information:

Step	Action
1	In the DTM Browser, find the name that is assigned to the CPU.
2	Right-click the CPU DTM, and select Device menu > Diagnosis .
3	In the left pane of the Diagnosis window, select the CPU node.
4	Select the Local Slave Diagnostic tab or the Connection Diagnostic tab to open that page.

Data Display

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.

Local Slave / Connection Diagnostic Parameters

This following tables display the diagnostic parameters for the selected local slave or scanner connection.

This table shows the Status diagnostic parameters for the selected connection:

Parameter	Description
Input	An integer representing input status.
Output	An integer representing output status.
General	An integer representing basic connection status.
Extended	An integer representing extended connection status.

The Input and Output status diagnostic parameters can present these values:

Input/Output Status (dec)	Description
0	OK
33	Time-out
53	IDLE
54	Connection established
58	Not connected (TCP)
65	Not connected (CIP)
68	Connection establishing
70	Not connected (EPIC)
77	Scanner stopped

This table shows the Counter diagnostic parameters for the selected connection:

Parameter	Description
Frame Error	Increments each time a frame is not sent by missing resources or is impossible to send.
Time-Out	Increments each time a connection times out.
Refused	Increments when connection is refused by the remote station.
Production	Increments each time a message is produced.
Consumption	Increments each time a message is consumed.
Production Byte	Total of produced messages, in bytes, since the communication module was last reset.
Consumption Byte	Total of consumed messages, in bytes, since the communication module was last reset.
Theoretical Packets per second	Packets per second calculated using current configuration value.
Real Packets per second	Actual number of packets per second generated by this connection.

This table shows the Diagnostic parameters for the selected connection:

Parameter	Description
CIP Status	An integer representing CIP status.
Extended Status	An integer representing extended CIP status.
Production Connection ID	The connection ID for the data produced by the local slave.
Consumption Connection ID	The connection ID for the data produced by the local slave.
O -> T API	Actual packet interval (API) of the production connection.
T -> O API	Actual packet interval (API) of the consumption connection.
O -> T RPI	Requested packet interval (RPI) of the production connection.
T -> O RPI	Requested packet interval (RPI) of the consumption connection.

This table shows the Socket Diagnostics diagnostic parameters for the selected connection:

Parameter	Description
Socket ID	Internal identification of the socket.
Remote IP Address	IP address of the remote station for this connection.
Remote Port	UDP port number of the remote station for this connection.
Local IP Address	IP address of the communication module for this connection.
Local Port	UDP port number of the communication module for this connection.

This table shows the Production diagnostic parameters for the selected connection:

Parameter	Description
Sequence Number	The number of the sequence in the production.
Max Time	Maximum time between two produced messages.
Min Time	Minimum time between two produced messages.
RPI	Current production time.
Overrun	Increments each time a produced message exceeds RPI.
Underrun	Increments each time a produced message is less than RPI.

This table shows the Consumption diagnostic parameters for the selected connection:

Parameter	Description
Sequence Number	The number of the sequence in the consumption.
Max Time	Maximum time between two consumption messages.
Min Time	Minimum time between two consumption messages.
RPI	Current consumption time.
Over Run	Increments each time a consumed message exceeds RPI.
Under Run	Increments each time a consumed message is less than RPI.
