Module Properties - General for 1771-ACN
Use this tab to create and configure the 1771-ACN15 and 1771-ACNR15 (Redundant Media) adapter modules.
TIP:
In order to create these modules, the parent module must be a 1756-CNB or a 1756-CNBR.
On this tab, you can:
- view the catalog number and description of the module being created
- view the vendor of the module being created
- enter the name of the module
- enter a description of the module
- select the desired communication formats
- specify a minor revision number for the module
- specify a node
- enter the input and output connection size or addressing mode
- select a keying option
Parameters
Type
Displays the type and description of the module being created (read only).
Vendor
Displays the vendor of the module being created (read only).
Name
Enter the name of the module.
The name must be IEC 1131-3 compliant. This is a required field and must be completed; otherwise you receive an error message when you exit this tab. An error message is also displayed if a duplicate name is detected, or you enter an invalid character. If you exceed the maximum name length allowed by the software, the extra character(s) are ignored.
IEC-61131 Name Standard
(The names are composed per IEC-61131, section 2.1.2.)
An identifier is a string of letters, digits, and underline characters that begin with a letter or underline character. Underlines are significant in identifiers (for example, A_BCD is interpreted differently than AB_CD). Multiple leading or multiple (consecutive) embedded underlines are not allowed, trailing underlines are not allowed, and letter case is not considered significant.
TIP:
In Logix Designer, most component names are limited in length to 40 characters or less.
Description
Enter a description (128 characters maximum) for the module. You can use any printable character in this field. If you exceed the maximum length, the software ignores any extra character(s).
Comm Format
Select the communication format for the module. This field lists the available formats.
Revision
Displays the Major revision number of the module. Enter a number representing the
minor revision. The range is from 1 - 255.
major revision
A functional change to the module. The major revision indicator is updated anytime this
occurs.
minor revision
A change to a module that does not affect its function or interface. The minor revision
indicator is updated when this occurs.
Node
Select the node number.
The Node is constrained by the available nodes on the ControlNet network between 1 and 99. If you select a node that is already in use, an error message is returned when you exit the General tab.
ControlNet network
An open control network that uses the producer/consumer model to combine the functionality of an I/O network and a peer-to-peer network, while providing high-speed performance for both functions.
Input Size
Enter the input connection size for your connection. The size you choose is reflected in the resulting module-defined data type after module creation. Your system’s chassis size and addressing mode determines the correct connection size to be used. For example, for a 4-slot chassis using a 1/2-slot addressing mode, an input size of 8 consumes discrete data from all slots.
Output Size
Enter the output connection size for your connection. The size you choose is reflected in the resulting module-defined data type after module creation. Your system’s chassis size and addressing mode determines the correct connection size to be used. For example, for a 4-slot chassis using a 1/2-slot addressing mode, an output size of 8 produces discrete data to all slots.
Electronic Keying
Electronic Keying
Electronic Keying reduces the possibility of using the wrong device in a control system. Electronic Keying compares the device defined in the project to the installed device. If keying fails, a fault occurs.
These attributes are compared:
Attribute | Description |
Vendor | The device manufacturer. |
Device Type | The general type of the device, for example, digital I/O module. |
Product Code | The specific type of device. The Product Code maps to a catalog number. |
Major Revision | A number that represents the functional capabilities of a device. |
Minor Revision | A number that represents behavior changes in the device. |
For more information on Electronic Keying, see Electronic Keying in http://literature.rockwellautomation.com/idc/groups/literature/documents/at/logix-at001_-en-p.pdf Control Systems Application Technique, publication LOGIX-AT001.
Status
Displays the status the controller has for the module:
This status: | Indicates: |
Standby | a transient state that occurs when shutting down |
Faulted | the controller is unable to communicate with the module When the status is Faulted, the Connection tab displays the fault. |
Validating | a transient state that occurs before connecting to the module |
Connecting | a state that occurs while the connection(s) are being established to the module |
Running | the module is communicating and everything is working as expected |
Shutting Down | the connections are closing |
Inhibited | the connection to the module is inhibited |
Waiting | a connection to this module has not yet been made due to one of the following:

Offline | you are not online |
