16.1.6 SFC 233 - CONTROL - Control page frame
The purpose of the CONTROL block is the following:
n Update of the indicator word
n Query if a certain order of the CP is currently "active", e.g. request for a receipt tele-
gram
n 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 RLO and should be called from the cyclic part of the application.
Parameters
Name Declaration Type Description
SSNR IN INT Interface number
ANR IN INT Job number
PAFE OUT BYTE Parameterization error
ANZW IN_OUT DWORD Indicator word
If ANR ¹ 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).
