Tab: Objects (object list)

The Objects tab of the safety application object is the object list. In this view the current project is compared with the last-pinned version of the project.

. Area with Pin information

: Pin information or, if the application has been changed: In Work
: Current CODESYS Safety Extension version
: Current Pin of the safety application, consisting of:
- Name
- CRC (pin CRC)
- Revision
- Last change

For detailed information about the pin information, see Pinning

Pin CRC

The pin CRC is a CRC for all objects of the safety application including the library blocks employed.

Layout of the tab

The comparison view ("Objects" tab) shows the following information:

. Listing of the objects belonging to the safety application with

Object
- Line
  Sequential numbers of the entries
- Type
  Object type (see table)
- Name
  Name of the object
- Domain
Project
- Version and Content CRC
  Version and CRC of the object in the current project (Project state column)
Pinned State
- Version and Content CRC
  Version and CRC of the last-pinned object
Buttons
- Clear pin
- Pin project

Tip

The object list also contains entries for all safety objects from the libraries which the application integrates. Only those referenced from the objects of the application are included. However, this also includes objects from the libraries that are not called from the user code, but from the system code, in particular from the I/O drivers.

Table 1. Displayed values for type and name in the object list (depending on the type of object)

Object type	Type	Name
Application	`APP`	Name of the application object
Task	`TASK`	Name of the task object
POU program	`PRG`	Name of the program POU
POU function block	`FB`	Name of the POU object of the function block
Global variable list	`GVL`	Name of the GVL object
I/O mapping	`MAP`	Name of the logical device object/application parameter
Safe configuration	`CNF`	Name of the logical device object/application parameter
Safe parameterization	`PAR`	Name of the logical device object

In addition, the object list contains the Clear pin and Pin project buttons. You can find a detailed description of these commands in Pinning.

Display of the differences between the pinned status and the project status

Differences detected during the comparison are displayed as follows:

The contents of an object were changed, and the Content CRC of the Project State is marked red.
A new object was added, and the Object and Project State are marked green.
An object was deleted: The Object is marked blue.

Update

The object list is automatically updated on opening the editor and executing the Pin project and Clear pin commands.
