The user (PLC) detects a change in the update counter value, and confirms that the NORM signal has turned
ON. Thereafter, the user (PLC) updates the update counter response value in accordance with the value of
the Update counter in the V780 response area, and turns OFF the EXE signal. This tells the Reader/Writer to
stop execution.
