(2) List of output signals (Signal direction: Programmable controller CPU
QD64D2)
* 1 The signal is only used for the coincidence output function.
* 2 The signal is only used for the continuous comparison function.
POINT
(1) The reserved signals above are for system use, not for users. If used (turning
ON/OFF) by a user, the functions of the QD64D2 are not guaranteed.
(2) Definitions of the expression in Operation timing are as follows.
•
:Enabled while the signal is ON.
ON time should be 2ms or longer.
•
:Enabled when the signal is turned from OFF to ON.
ON time and OFF time should be 2ms or longer.
