| The following figure shows an OB that calls one FB three times, | such as motors, by assigning a different instance data block for each call for the different devices. |
| using a different data block for each call. |
Each instance DB stores the data (such as speed, ramp-up time, and total operating time) |
| This structure allows one generic FB to control several similar devices, | Each instance DB stores the data (such as speed, ramp-up time, and total operating time) |
data for the first device, DB 202 storing the operational data for the second device, and DB
203 storing the operational data for the third device.In this example, FB 22 controls three separate devices, with DB 201 storing the operational
data for the first device, DB 202 storing the operational data for the second device, and DB
203 storing the operational data for the third device.The data stored in a DB is not deleted when the execution of the associated code block
comes to an end. There are two types of DBs:
● A global DB stores data for the code blocks in your program. Any OB, FB, or FC can
access the data in a global DB.
● An instance DB stores the data for a specific FB. The structure of the data in an instance
DB reflects the parameters (Input, Output, and InOut) and the static data for the FB. (The
Temp memory for the FB is not stored in the instance DB.) Although the instance DB reflects the data for a specific FB, any code block can access
the data in an instance DB. You can configure a DB as being read-only:
1. Right-click the DB in the project navigator and select "Properties" from the context menu.
2. In the "Properties" dialog, select "Attributes".
3. Select the "Data block write-protected in the device" option and click "OK". Use the "Add new block" dialog
under "Program blocks" in the
Project navigator to create OBs,
FBs, FCs, and global DBs.
When you create a code block, you
select the programming language
for the block. You do not select a
language for a DB because it only
stores data
A communication request from an HMI device or another CPU can also interrupt execution of the program cycle OB.
The communication requests can also cause issues with data consistency. The CPU ensures that the elementary data types are always read and written consistently by the user program instructions. Because the user program is interrupted periodically by communications, it is not possible to guarantee that multiple values in the CPU will all be updated at the same time by the HMI. For example, the values displayed on a given HMI screen could be from different scan cycles of the CPU.
