PART 1: CX-Programmer
CHAPTER 4 – Reference
OMRON
CX-Programmer _Page 62
Data Types and Timer/Counters
Information for a timer/counter on a PLC consists of three parts – a status bit, a pre-set-value and the current
value. Different data-types are used to refer to these different parts. These three parts can set to different
comments, but to set the same comment for all three parts, use I/O Comment view to input a comment - Refer to
I/O Comment View
in
Chapter 4 Reference
for further information. When there is no comment in the symbol
with a NUMBER or a UINT data-type, the comment of the symbol with a BOOL data-type will be shown on the
right of the right-busbar instead.
Note:
When defining a timer number or counter number as a variable for PLCs other than CJ2 PLCs,
use the previous method. (TIMER and COUNTER data types are supported only by CJ2 CPU
Units.)
Structure Symbols
Specifying Structure Symbols
A data structure is a user-defined data type that can contain more than one data type.
Names can be assigned to the data types.
(Supported only for CX-Programmer version 9.0 or higher and CJ2 CPU Units.)
•
Ladder Program Notation for and Inputting Structure Symbols
In a Ladder Program, the structure symbol name and member name are separated by a period.
Example:
Note:
If a member is also a data structure, another period is used to specify the member.
Period
abc . def . member1
Structure name
def
Structure name
Period
Member name
= Means “member 1 of def of abc.”
Creating Data Types for Data Structures
Use the following procedure to create a data type for data structures.
•
Inserting New Data Types for Data Structures
1. Double-click the Data Types Icon in the project workspace.
2. Select
Struct
from the Insert Menu.
The Edit Structure Dialog Box will be displayed.
3. Input a name for the structure data type.
4. Click the
OK
Button. The structure data type will be inserted into the data type view.
•
Inserting a New Member
1. To add a member as the last member of the structure data type, select the data structure.
To insert a new member before a member, select the member.
2. Select
Member
from the Insert Menu.
The Edit Structure Dialog Box will be displayed.
3. Input a name for the member.
Select the data type of the new member.
Set the array size to 0 if the new member is not an array.
abc. member1
Structure name
Period
Member name
= Means “member 1 of abc.”
