Standard Mode
The individual bits are independent of each other.
The Write Coordination byte only works together with the Read Coordi-
nation byte.
5.14.1 External Data Release
The controller can use the External Data Release bit to influence data
release in the operating device. If the operator would like to change a
value in the operating device, he must first request data release. For
this purpose, the operating device writes a logical 1 to the Editing
Request bit in the Read Coordination byte. During this time, the Data
Release status LED flashes.
Once the controller establishes that the Editing Request bit in the Read
Coordination byte is set to logical 1, it can release the editing process
in the operating device by setting the External Data Release bit in the
Write Coordination byte to logical 1. The Data Release status LED is
then lit.
5.14.2 Refresh Acknowledgment
Once the controller has read the Refresh Request bit in the Read Coor-
dination byte as logical 1, it can read in the changed variable value.
When finished, the controller can write a logical 1 to the Refresh
Acknowledgment bit, and confirm execution to the operating device.
5.14.3 Delete Password
When the operator exits a mask for which he requires a password for
access, password protection needs to be activated again for this mask.
This can be forced by the controller by entering a logical 1 in the Delete
Password bit.
