The figure on the left shows the parameter display and the parameter set for
the function block TB16. Once function block number 16 has been defined,
you set here the operands for the production code at input TB16I1 and the
output TB16QV.
The coils and contacts are programmed in the circuit diagram of easy800:
Figure 200:Table function example
•
The enable coil TB16EN is permanently active, the function block is not
switched off.
•
With a rising edge of marker M01 write clock pulse coil TB16WP for
reading the production code from MD10 and transfers it to the table.
•
The contact TB16TF is used to show the sixteenth entry via the marker
M 05 to the operator.
•
With a rising edge from marker M02 to TB16RF the processing station
reads out the first production code from the table and supplies it at
output TB16QV.
•
After the sixteenth read process or less, all production codes have been
read out and the table is empty. Contact TB16TE closes.
