DG, diagnostics

The diagnostics function block (DG function block) evaluates
the status messages of a safety function block. A status
message is connected in the standard function block
diagram with a contact of the DG function block. The contact
closes if the message occurs. This can be responded to in the
user program: To do this create a text using the text display
function block. After the contact closes, the text can be
shown on the display or on a connected visualization device.
The DG function block can only be edited with the easySoft-
Safety configuration software. This allows the use of up to
16 diagnostics function blocks.
