4 When the conditions for triggering the return stroke have been met and the
minimum time has been reached (must be integrated in the overriding con-
trol), the 'Start' signal is reset. The measurement is evaluated when the <S-
tart> signal is reset.
5 If the measurement lies within the programmed window, signal <OK> is set.
If the measurement lies outside the programmed window, signal <OK> is not
set. If the OK signal is missing it must be evaluated as NOK in the external
control after a waiting period of at least 200 ms.
If the warning limit or the number of pieces of a measurement channel has
been exceeded in the finished cycle, the output <Warning limit/Number of
pieces (NOK)> is also set. This signal can now be evaluated in the external
control.
Plant control system: check the readiness of measurement
Before the command "Start measurement" it must be checked whether th
CEP 400T is ready for measuring.
The process monitoring system might not be ready to measure due to a
manual input or a fault. It is therefore always necessary prior to an
automatic sequence to check the 'Ready to measure' output of the system
controller before setting the 'Start' signal.
Signal name Type:
Input "I" / Output "O"
Designation
E0 I Program number bit 0
E1 I Program number bit 1
E2 I Program number bit 2
E3 I Program number bit 3
E10 I Program number bit 4
E11 I Program number bit 5
E4 I Program number cycle
A4 o Program number acknowledgement
Tab.16 Automatic program selection
The program number bits 0,1,2,3,4 and 5 are set binary as test plan num-
ber from the system controller. With a rising edge of the timing signal from
the system controller this information is read from the CEP 400T device
