Introduction

The Device List contains read-only properties that summarize these items:

  • configuration data:

    • input data image

    • output data image

    • maximum and actual numbers of devices, connections, and packets

  • Modbus request and EtherNet/IP connection summary

Step

Action

1

Open your Control Expert project.

2

Open the DTM Browser ( Tools > DTM Browser) .

3

Double-click the CPU DTM in the DTM Browser to open the configuration window.

NOTE: You can also right-click the CPU DTM and select Open.

Configuration Summary Data

Select Device List and view the Configuration Summary table on the Summary tab to see values for these items:

  • Input

  • Output

  • Configuration Size

Expand (+) the Input row to view the Input Current Size values:

Description

Source

This value is the sum of Modbus requests and EtherNet/IP connection sizes.

This value is configured in the General page for a selected distributed device and connection.

Expand (+) the Output row to view the Output Current Size values:

Description

Source

This value is the sum of Modbus requests and EtherNet/IP connection sizes.

This value is configured in the General page for a selected distributed device and connection.

The maximum size of the X Bus input or output memory variable is 4 KB (2048 words). The variable contains a 16-byte descriptor followed by a value that represents the number of input or output data objects. Each data object contains a 3-byte object header followed by the input or output data. The number of data objects and the size of the input or output data depend on the configuration. The maximum overhead in the variable is 403 bytes (16 + 387), where 16 is the number of bytes in the descriptor and 387 is the product of 3 x 129, where 3 is the number of bytes in the header and 129 is the number of input or output objects (128 maximum scanned devices or local slaves that the BMENOC03•1 module supports plus one input or output object for the scanner DDDT). Therefore, at least 3.6 KB of the 4-KB variable is available for the input or output current size.

NOTE: The input current size also includes 28 words of scanner DDT input data. The output current size also includes 24 words of scanner DDT output data.

Request / Connection Summary Data

Select Device List and view the Request / Connection Summary table on the Summary tab. The Control Expert DTM uses this information to calculate the total bandwidth that distributed equipment consumes:

Column

Description

Connection Bit

  • Connection health bits display the status of each device with one or more connections.

  • Connection control bits can be toggled on and off using object IDs.

Task

The task that is associated with this connection.

Input Object

The ID of the input object associated with the connection (see the note following the table).

Output Object

The ID of the output object associated with the connection (see the note following the table).

Device

The device Number is used for the health and control bit index.

Device Name

A unique name associated with the device that owns the connection.

Type

The target device type:

  • EtherNet/IP

  • Local Slave

  • Modbus TCP

Address

The target device IP address for remote devices (does not apply to local slaves).

Rate (msec)

The RPI (for EtherNet/IP) or the repetitive rate (for Modbus TCP), in ms.

Input Packets per Second

The number of input (T->O) packets per second exchanged over this connection.

Output Packets per Second

The number of output (O->T) packets per second exchanged over this connection.

Packets per Second

The total number of packets per second exchanged over this connection in both Input and output directions.

Bandwidth Usage

The total bandwidth used by this connection (total bytes per second traffic).

Size In

The number of input words configured for this remote device.

Size Out

The number of output words configured for this remote device.
NOTE: The numeric identifiers in the Input Object and Output Object columns represent the objects associated with a single device connection (scan line). For example, if an EtherNet/IP connection has an input object of 260 and an output object of 261, the corresponding control bits for this connection are in the DIO_CTRL field in the M580 CPU device DDT. Object 260 is the fifth bit and object 261 is the sixth bit in this field. There can be multiple connections for a device. Set the corresponding bits to control the input and output objects for these connections.
