Module Properties - General for 1788-EN2DN
Use this tab to create/view module properties for the 1788-EN2DN ControlNet to DeviceNet Linking module.
On this tab, you can:
- 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 ControlNet node number where the module resides
- enter connection parameters 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.
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 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).
Comm Format
Displays the type of data being exchanged between the parent and the adapter. The Major Revision, connection, and module mode may limit the available types of data formats to choose from.
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
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.
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. Input Size
Enter the input connection size for the primary connection.
Output Size
Enter the output connection size for the primary connection.
Status Size for the 1788-CN2DN Module Only
Enter the input size for the status connection. The default value is 32. The Status module-defined data types names generated reflect the size you choose.
