we are using ac450 and 800xa 5.0 ,in our plant we have sequence and central mode for motor faceplate.
sequence mode is used for group start/stop and manual mode is for individual start/stop
here we are not using auto/MANUAL button.
i just want to control the motor faceplate changing from manual mode to sequence automatically , after some time or from Controller program bits .when the motor is in Central mode.
if you check the definition of the Seq button (Config View of the Faceplate in the Object Type Structure), you will find that it sets the MORD_15 property. This property corresponds to the 15th bit of the :MORD terminal of the MOTCON database element. So setting this bit for one program cycle should do the job.
Please find attached program example, setting the SWITCH_TO_SEQ terminal will switch the motor to sequence mode.
