Standard Mode
5.13.1 Editing Request
The operating device uses the Editing Request bit to indicate to the
controller that the value of a variable will be changed.
For this purpose, the operating device writes a logical 1 to the Editing
Request bit in the Read Coordination byte.
To allocate an editing release to the operating device, the controller
writes a logical 1 to the Editing Release bit in the Write Coordination
byte.
5.13.2 Editing Status
The operating device uses the Editing Status bit to indicate to the con-
troller that the value of a variable could be changed.
Once the operating device has received the Editing Release from the
controller, the device sets the Editing Status bit in the Read Coordina-
tion byte to logical 1.
The operator can now change the variable value. To send the changed
variable value to the controller, the operator must select the Enter key
to complete the entry.
The operator can then change other variable values.
Then, the operator must press the Data Release key. This resets the
Editing Status bit to logical 0.
The Refresh Request and Refresh Acknowledgment bits are used
to write the new variable value to the controller.
Once the controller has read the new variable value, it uses the
Refresh Acknowledgment bit to indicate of the Write Coordination
byte that the Editing Status bit can once again be reset to logical 0.
5.13.3 Refresh Request
If you changed a variable value in the operating device, and selected
the Data Release key, the Refresh Requestbit in the Read coordina-
tion byte must be set to logical 1.
This triggers the read process in the controller, and then confirms it
with the Refresh Acknowledgment bit in the Write Coordination byte.
