Panel blocks, general
3
To operate and monitor the process on an operator panel in addition to using an OS it is
necessary to use interface blocks (Pxxx) for communication. These blocks form the HMI
interface with the operator panel.
For example to operate and monitor the field device MAG 6000 via OS and an operator panel,
it is necessary to implement the following blocks:
● Technological function block Mag6T to operate the field device MAG 6000
● Operator panel function block PMag6T as interface to function block Mag6T and the panel
(WinCC-flexible)
The technological block and panel block communicate using an ANY pointer connection. In
other words, communication can be established simply by connecting the BlockConnector
input of the panel block to any output (apart from ENO) of the technological block. All necessary
values are read and written using this connection.
If an error is detected in this connection (for example, if the BlockConnector input is connected
to a technological block that is not associated with the panel block), the DB_ConnErr output of
the panel block is set to 1.
The instance DBs of the operator panel blocks act as the HMI interface with the operator panel.
They have an individually defined "structure" which is dependent on the type of equipment
concerned.
Create a data block, used as ‘communication-DB’, in the S7 program. The numbers of the
instance data blocks of the used panel blocks are stored in this block as integers. Connect the
IDBNo output of the panel interface block to the parameter of the DB.
Note
It is sufficient to use one DB containing the IDB number entries of the panel blocks used.
