Step 2.7. Create CIMPLICITY Device Points to Access Machine Edition Variables| CIMPLICITY 11.1 Documentation

1	Create a point.
2	Configure the General tab.
3	Configure the Device tab.
4	Complete point configuration.

Create a point.

Double-click Points in the Workbench left pane.

Note: You can use any of the available methodsto create a new device point.

A New Point dialog box opens.

Enter and select the following.


Field	Description
Point ID	Name of the CIMPLICITY point that will access a selected Machine Edition variable's values. The name does not have be the same as the Machine Edition variable name, but it can be.
Type	Device	Device created to communicated with the Machine Edition project.
Class	Must correspond to ??the selected Machine Edition variable.

Click OK.

Result: The Point Properties - <Point name> dialog box opens.

Configure the General tab

Select the General tab.
Make sure the following is entered/selected.


Field	Description
Description	(Optional) Point identification.
Data type	Machine Edition variable data type defined as a CIMPLICITY data types.
Elements	Same number of elements as the Machine Edition variable. If the point is an array
Read only	Check	If the Machine Edition variable cannot be set.
	Clear	If the Machine Edition variable can be set.
Enable point	Check	Enable the point.
Resource ID	Resource configured for Machine Edition variables.

Configure the Device tab

Select the Device tab.
Make sure the following is entered/selected.


Field	Description
Device ID	Device created to communicate with the Machine Edition project.
Address	Machine Edition variable name. Any Machine Edition variable that corresponds to the point definition can be entered, including an array element. Important Two CIMPLICITY points cannot be configured to access the same Machine Edition variable. POINT_BRIDGE checks for duplicate address names. If two points use the exact same names in the Address field, only the first point will be validated. A duplicate name log will be entered in the status log for the second point. Example A CIMPLICITY point, CSin1, is configured to access a Machine Edition variable, Sine1. A second CIMPLICITY point, e.g. CSin1_2 cannot access data from the same variable, Sine1. Two or more CIMPLICITY points can be configured to access different elements in an array variable, including the array variable itself. POINT_BRIDGE views points that access different elements in an array as non-duplicate points. Each of the array element points will be validated. Creating different CIMPLICITY points for elements is more efficient than creating a single point for the array variable Example A CIMPLICITY point, MARRAYDINT[2], is configured to access element 2 in a Machine Edition variable, ARRAYDINT. Another CIMPLICITY point MARRAYDINT[3] can also access element 3 in the same Machine Edition variable, ARRAYDINT. Note: When a CIMPLICITY point that accesses a Machine Edition array element is updated, values for every element in the array are transmitted back to Machine Edition. As a result, in some rare instances old array element values from CIMPLICITY may overwrite new array element values in Machine Edition. Example A CIMPLICITY point, CARRAY2, is configured to access ??a Machine Edition array element, MARRAY[2]. The Machine Edition array element, MARRAY[5] has changed from 9 to 11. However, this change has not been transmitted to CIMPLICITY; CIMPLICITY still has the old Machine Edition array element values. A CIMPLICITY user sets the CIMPLICITY point CARRAY2 value from 6 to 10. Values for every element in MARRAY are transmitted from CIMPLICITY back to Machine Edition when the CIMPLICITY point is set; this includes the old MARRAY[5] value, 9. The old MARRAY[5], 9, from CIMPLICITY overwrites Machine Edition's new value, 11.

Complete point configuration

Click OK.
Repeat this step to create all required points.

Result: The configured points will now report Machine Edition variable data. Read/write points can be used to set values in the Machine Edition project.
