I/O CONTROLNET SCREENS

1. I/O CONTROLNET BOARD LIST SCREEN

The Board List identifies the overall Network Status of both ControlNet Boards that can be used in a ControlNet system.

Table 1.  ControlNet Board List Screen Items

ITEM DESCRIPTION

Board

 

Comment

You can use this text field to identify the ControlNet Network to which this Board is connected. For example, on which Body Cell Network the node is attached. A maximum of 16 characters can be used. A comment is not a required field.

Rack

This is the I/O rack that is assigned to the daughterboard. These are unique rack numbers throughout the system. ControlNet daughterboards are assigned Racks 85 and 86.
  • Rack 85 - daughterboard 1

  • Rack 86 - daughterboard 2 You cannot change the rack number of a ControlNet daughterboard.

Status

STATUS is the current state of the ControlNet PCB
  • ONLINE indicates the board is presently active. Information to and from devices configured on this network is being updated.

  • OFFLINE indicates that no data is being transferred to or from devices connected to the board. Scanning of devices connected to this board shall not automatically restart at power up. The user must explicitly set this Board ONLINE in order to transfer I/O.

  • ERROR indicates that an error has been detected. The Inputs will be set to the state you designated in the Board Detail Screen. I/O transfer will begin immediately when the condition causing the ERROR is removed. Scanning shall also be attempted after the controller is turned on.

Table 3.  ControlNet Board Detail Screen Items

ITEM DESCRIPTION

MAC-ID

This item is the MAC ID of the ControlNet Interface board.

Network Update Time (NUT)

This item displays the Network Update Time, which is the basic time period for devices to communicate on the Network. A NUT consists of three required periods. The first period is the Scheduled data period in which all the Scheduled Nodes are allowed to communicate until all devices on the scheduled nodes have exchanged their data. The second period is the Unscheduled data period in which each node is sequentially allowed to transmit an unscheduled message. If there is any time remaining in this interval, then the next node will be allowed to transmit an unscheduled message. Message transmission can be continued until the Guardband time period is reached. When the Guardband time period begins, network maintenance is performed. This ends the NUT. It is immediately followed by another NUT in which scheduled data is exchanged.

SMAX

The Scheduled Maximum MAC ID number on the network (1-92). Only the nodes which are in this address range (and node 0) might transmit messages during the scheduled interval.

UMAX

The Unscheduled Maximum MAC ID number on the network (1-99) is the MAC ID of the last node that might send unscheduled messages on the network. It must be at least SMAX + 8.

Slot Time

The Slot Time, in microseconds (us), is the time that nodes wait to see if the node that currently has the token is going to use it.

Gbpre

This item displays the Guardband Prestart, in 10µs intervals, and it is the time before the next synchronization mark beyond which nodes will not be allowed to transmit.

GBstrt

This item displays the Guardband Start, in 10µs ticks, and it is the time before the next synchronization mark where the guardband should start.

Gbcenter

This item displays the Guardband Center, in 10 µs ticks, and it is the time before the next synchronization mark, where the moderator will begin transmitting the moderator frame. The moderator frame is used to synchronize the network and distributing the link configuration parameters.

3. I/O CONTROLNET TCP/IP CONFIGURATION SCREEN

Table 5.  I/O ControlNet TCP/IP Configuration Screen Items

ITEM DESCRIPTION

IP Addr

This item is the IP address for the ControlNet Interface. The domain of the IP address should be different than that of any Ethernet or PPP interface that you might have configured on the controller.

Subnet Mask

This item is the subnet mask that corresponds to the IP address. Note that the domain should be the same as that of the other ControlNet devices you have on the network for TCP/IP communications (such as a PC or another controller).

Enable TCP/IP

This item allows you to use TCP/IP. To use TCP/IP, set this item to YES.

4. I/O CONTROLNET ADAPTER CONFIGURATION SCREEN

Table 6.  Adapter Configuration Screen Items

ITEM DESCRIPTION

Input Size

This is the size in words of the receive or input connection, designated in ControlNet by O=>T. The 8 words of input identify 128 Digital Inputs. This represents data received from a scanner over the network.

Output Size

This is the size in words of the send or output connection, designated in ControlNet by T=>O. The 8 words of output identify 128 Digital Outputs. This represents data transmitted to a scanner over the network.

Output Header

The Digital Outputs shall be read into the scanners input data file or data structure. This data is generally written starting at the beginning of the data structure. However, if the scanner structure includes a header structure, then the controller output data needs to be offset from the beginning of the structure. The normal Output Header of a 2711E-T14 is 2 words.

6. I/O CONTROLNET I/O CONFIGURATION FOR DEVICE SCREEN

Table 10.  ControlNet Device Detail Screen Items

ITEM DESCRIPTION

Input Header Words

This item indicates the Input Header size in words. This is fixed for most devices by the CNET Spec to two words. This field contains the Run/Idle bit. This bit is used by the Scanner to enable the outputs. The Scanner's outputs are then sent to the device as inputs.

Status

This item lists the status of the device you are displaying details about. The status of the device can be ON, OFF, or ERR on a device basis (same as Device List Status).

MAC-Id/Slot

This item displays the MAC-ID of your ControlNet interface, or a device being scanned by your ControlNet Interface. If the MAC Id being displayed in this field matches the ControlNet Interface's MAC Id, then the data being displayed on the device detail screen is from the ControlNet Interface. If the MAC Id is not equal to the ControlNet Interface's MAC Id, then the data being displayed on the Device Detail screen is from a unit being Scanned. The MAC Id is same as the Slot when configuring I/O from any of the DI/DO, GI/GO, AI/AO, and so forth screens.

Device Name

This item allows you to provide a name for the device you are configuring.

Comment

This item allows you to enter a comment. Although 16-characters can be entered here, only 14 of them shall show up on the Device List Description field.

Vendor ID

This item is the unique identification of the device's vendor. For Example, Vendor ID 1 is assigned to Rockwell Automation's Allen-Bradley devices, and Vendor ID 8 is assigned to SS Technologies.

Device Type

This item displays the Device Type. Device Types identify the device profile or device object that a device is using. For example, Device Type 24 or 0x18 is a Human-Machine Interface (HMI).

Product Code

This item displays the Product Code for the device. Each Vendor assigns a Product Code within a particular Device Type. The Product Code maps to one or more catalog or model numbers. For example, Allen-Bradley has assigned product code 9 of the HMI Device type to the 2711E-T14C15.

Major Revision

This item represents significant releases of 'fit, form, or function' of the product.

Minor Revision

This item indicates that minor changes were made to a given product. These kinds of revisions probably will not affect the way your network is configured. Minor revisions might include new product labels or software patch files.

Digital Inputs

This item is the number of physical inputs that the device can support, in bits.

Digital Outputs

This item is the number of physical outputs that the device can support, in bits.

Analog Inputs

This item is the number of physical analog input points which the device supports. This item is displayed in ControlNet words (16-bits/word).

Analog Outputs

This item is the number of physical analog output points which the device supports. This item is displayed in ControlNet words (16-bits/word).

O-T RPI

This item is the requested packet interval for data from scanner to adapter.

T-O RPI

This item is the requested packet interval for data from adapter to scanner.

Path:

This item is the connection path--the path in the adapter from where I/O is read and written. The path configured in the scanner should match what is expected in the adapter. If it does not, ControlNet error 01 0107 will be posted on the scanner.
