Module Properties - General for FLEX-MODULE
Use this tab to create or view module properties for the FLEX-MODULE Generic module.
On this tab, you can:
- View the type and description of the module being created
- View the name of the parent module
- Enter the name of the module
- Enter a description for the module
- Select the communication formats: non-I/O modules for the module
- Enter the slot 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).
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
Select the communication format for the module. This field lists the available communication formats for the module.
When you choose a communication format, you are also defining the configuration formats for the module.
TIP:
Once you create a module, you cannot change the communication format. To change configuration, you must delete and recreate the module.
Slot
Enter the slot number where the module resides. This value is dependent upon the size of the chassis and the currently-occupied slots. Chassis size is determined by the configuration of the parent adapter.
Connection Parameters
TIP:
The FlexBus supports 3 types of modules: 3-word, 15-word, and EDT modules. Generally, discrete I/O modules are 3-word, and non-discrete I/O modules are 15-word.
This word count refers to the size of the transfer on the backplane. For a 15-word module, the 15 words can each be used only for Read or Write (Input and Status are Read; Output and Configuration are Write), and the total of Input, Status, Output, and Configuration cannot exceed 15 words. For EDT modules, the total of Input, Output, and Status cannot exceed 13 words. The Configuration tag can be much larger for these modules.
Input
Enter the size of the input assembly. Valid values range from 0 through 15; the default value is 1. This value is valid for all comm formats.
Output
Enter the size of the output assembly. Valid values range from 1 through 15; the default value is 1. This value is valid only for the Data - INT comm format, and is unavailable for the Input Data and Listen Only comm formats.
Configuration
Enter the size of the configuration assembly, including safe state values. Valid values range from 0 through 185; the default value is 0.
The configuration data type associated with this module is a fixed size (370 bytes), but only the amount of the data indicated by this parameter is sent as configuration data. If you specify a configuration size of 0, a configuration data type and tag are still created, but no configuration information is sent to the module.
TIP:
The size that you enter here must consider:
- The configuration required for the module.
- For output modules, the configuration required for the safe state data for the module (that is, the size of the output tag).
The configuration tag that is generated is larger than the value you enter in this Configuration field because this tag also includes controller and adapter configuration information. Bear this in mind when considering the size you enter here.
Status
Enter the size of the status assembly. Valid values range from 0 through 15; the default value is 1. This value is valid for all comm formats.
