6.2. Timing chart
Below examples are when the station number is set to 1.
When connecting to a power supply
When the AD-8923-CC is connected to a power supply and the CC-Link is
ready, the request flag of initialization (RX0018) becomes active.
The master station confirms that RX0018 is active, performs initialization
and turns the reply flag of initialization (RY0018) ON.
The AD-8923-CC turns the request flag of initialization (RX0018) OFF and
turns the remote READY flag (RX001B) ON.
Turn OFF the reply flag of initialization (RY0018) in the master station.
Performance upon power-ON
Resuming from suspended modes
When the AD-8923-CC is in a mode that suspends weighing, such as
calibration or display-OFF, the remote READY flag (RX001B) becomes
inactive because a correct weight value can not be output.
To resume from this condition, take the same steps as described in “When
connecting to a power supply” above.
CPU operation
The CPU normal operation (RX0006) is a signal to check that the
AD-8923-CC is connected to a power supply and it functions normally.
During normal operation, the signal is reversed at an interval of 0.5 to 1 second.
