Module Properties - General for 1756-EN, EW, 1768, 1769

Use this tab to create or view module properties for the:
  • 1756-ENET/A and 1756-EWEB/A modules
  • 1756-ENET/B, 1756-ENBT/A, and 1788-ENBT/F modules when used as scanners
  • 1756-EN2T
  • 1768-ENBT, 1769-L32E, 1769-L35E, and 1769-L23E Ethernet Bridge modules
On this tab:
  • view the type and description of the module being created
  • view the vendor of the module being created
  • enter the name of the module
  • enter a description for the module
  • enter the slot number where the module resides
  • enter the minor revision information for the module
  • select Exact Match, Compatible Module, or Disable Keying
  • view the status the controller has about the module (you can only view the status while online)
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).
Parent
Displays the name of the parent module.
Name
Enter the name of the module.
Use an IEC 61131-3 compliant name. This field is required. If incomplete, an error message appears when exiting this tab. An error message also appears if a duplicate name is detected, or an invalid character entered. If the maximum name length is exceeded, the software ignores the extra character(s).
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 for the module, up to 128 characters.Use any printable character in this field. If the maximum length is exceeded, the software ignores any extra character(s).
Slot
Enter the slot number where the module resides. The Slot number is not used when establishing a connection to the module. If an incorrect slot number is entered, CAN connect to the module because the Node number is read from the Current Path when establishing a connection to the module and not the Slot number.
The slot number cannot be changed when online.
Revision
Select the appropriate revision information for your module.
The revision is divided into the major revision and minor revision. The major revision indicates the revision of the interface to the module. Valid values are in the range from 0 to 127. The minor revision indicates the firmware revision. Valid values are in the range from 0 to 255, with 1 being the default value.
Change the Major Revision for a 1756-ENBT module offline or online. The revision information is immediately changed (no need to click Apply).
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.

Status
Displays the status the controller has about 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 was not made for one of these reasons:
  • its parent did not make a connection to it
  • its parent is inhibited
  • its parent is faulted
Offline
