Module Properties - General for 1756, 1788-EN

Use this tab to create/view module properties for the 1756-ENET/B, -ENBT/A, and 1788-ENBT/F modules as adapters.
On this tab, you can:
  • view the type and description of the module being created
  • view the vendor of the module being created
  • view the name of the parent module
  • enter the name of the module
  • enter a description for the module
  • enter the minor revision for the module
  • select Exact Match, Compatible Module, or Disable Keying
  • enter the IP address and host name for the module
  • 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.
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.
Description
Enter a description for the module here, up to 128 characters. You can use any printable character in this field. If you exceed the maximum length, the software ignores any extra character(s).
Slot
Enter the slot number where the module resides. The values range from 0 to 1 less than the chassis size (e.g., if you have a 4-slot chassis, values are from 0 to 3), except for the 1788-ENBT module, for which this value must be either a 1 or a 2. The Slot number is not used when establishing a connection to the module. If you enter an incorrect slot number, you 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 minor revision number of your module.
The revision is divided into the major revision and minor revision. The major revision is used to indicate the revision of the interface to the module. Valid values are in the range from 0 to 127. The minor revision is used to indicate the firmware revision. Valid values are in the range from 0 to 255, with 1 being the default value.
Electronic Keying
Select one of these keying options for your module during initial module configuration:
  • Exact Match - all of the parameters described below must match or the inserted module will reject the connection.
  • Compatible Module
    The following criteria must be met, or else the inserted module will reject the connection:
    • the Module Types, Catalog Number, and Major Revision must match
      TIP:
      One exception to the matching Module Type rule: You can replace the 1756-ENET/B adapter with a 1756-ENBT/A adapter and still satisfy compatible keying.
    • the Minor Revision of the physical module must be equal to or greater than the one specified in the software
  • Disable Keying - the controller will not employ keying at all.
    WARNING:
    DANGER:
     Changing the RPI and Electronic Keying selections may cause the connection to the module to be broken and may result in a loss of data.
WARNING:
DANGER:
 Be extremely cautious when using this option; if used incorrectly, this option can lead to personal injury or death, property damage or economic loss.
When you insert a module into a slot in a ControlLogix chassis, the
Logix Designer
 application compares the following information for the inserted module to that of the configured slot:
  • Vendor
  • Product Type
  • Catalog Number
  • Major Revision
  • Minor Revision
This feature prevents the inadvertent insertion of the wrong module in the wrong slot.
IP Address
Enter the IP address of the module.
IP address
  • The Internet Protocol (IP) address identifies each node on the IP network (or system of connected networks). Each TCP/IP node on a network (including the Ethernet module) must have a unique IP address.
  • The IP address is 32 bits long and consists of a net ID part and a host ID part. Each network is a Class A, Class B, or Class C network. The class of a network determines how an IP address is formatted.
  • Each node on the same physical network must have an IP address of the same class and must have the same net ID. Each node on the same network must have a different host ID, thereby giving it a unique IP address.
  • IP addresses are written as four decimal integers separated by periods (i.e., xxx.xxx.xxx.xxx), where each integer (or xxx) is a number between 0 and 255 which gives the value of one byte of the IP address.
  • The first octet of the IP Address may not be 127, or a number greater than 223.
For example, the 32-bit IP address:
00000011 00000000 00000000 00000001 is written as 3.0.0.1.
Distinguish the class of an IP address from the first integer in its dotted-decimal IP address as follows:
Range of first integer
Class of network
0 - 127
A
128 - 191
B
192 - 223
C
224 - 255
other
TIP:
You must enter either an IP address for the module OR a host name. You do not have to enter both. These items are mutually exclusive; once you choose one, the other will be disabled.
Host Name
Enter a host name for the module.
TIP:
You must enter either an IP address for the module OR a host name. You do not have to enter both. These items are mutually exclusive; once you choose one, the other will be disabled.
TIP:
The
Host Name
 parameter is not available when you configure safety devices. Host names require DNS lookup, which is not allowed for safety devices.
