CTRCLRT Example
Rung 1: This sets up the CTRIO card in slot 2 of the local base. Each CTRIO in the system
will need a separate CTRIO I-box before any CTRxxxx I-boxes can be used for them. The
CTRIO has been configured to use V2000 through V2025 for its input data, and V2030
through V2061 for its output data.
Rung 2: This rung is a sample method for enabling the CTRCLRT command. A C-bit is used
to allow the programmer to control the command from Data View for testing purposes.
Turning on C0 will cause the CTRCLRT instruction to clear the preset table for output #0 on
the CTRIO in slot 2.
Operating procedure for this example code is to load the CTRCLRT_ex1.cwb file to your
CTRIO, then enter the code shown here, change to RUN mode, enable output #0 by turning
on C2 in Data View, turn encoder on CTRIO to value above 10 and output #0 light will come
on and stay on until a count of 20 is reached, where it will turn off. Now reset the counter with
C1, enable C0 to execute CTRCLRT command to clear the preset table, turn on C2 to enable
output #0, then turn encoder to value of 10+ (output #0 should NOT turn on).
