SFC 233 - CONTROL
The purpose of the CONTROL block is the following:
•
Update of the indicator word
•
Query if a certain order of the CP is currently active, e.g. request for a
receipt telegram
•
Query the CP which order is recently in commission.
The CONTROL block is not responsible for the handshake with the CP, it
just transfers the announcements in the order status to the parameterized
indicator word. The block is independent from the VKE and should be
called from the cyclic part of the application.
If ANR
≠
0, the indicator word is built up and handled equal to all other
handling blocks.
If the parameter ANR gets 0, the CONTROL command transmits the
content of the order state cell 0 to the LOW part of the indicator words
The order state cell 0 contains the number of the order that is in
commission, e.g. the order number of a telegram (set by the CP).
