commences to operate the devices. Table 4.11-5 shows start commands.

Note: If a stop command is applied to the ASEQ01 function, the operation of the control
logic will be canceled promptly provided that the control logic is not operating the
device. Alternatively, the control logic can wait for the operation being completed,
if the control logic is able to determine to continue the operation. Table 4.11-4
shows the stop commands.
3
Note: See section 4.11.5. Table 4.11-9 and Table 4.11-10 show the emergency commands.
4
Note: After the reception of the start command, the execution state can be monitored.
Table 4.11-7 shows the execution states.
5
Note: The stop signal is provided for the logic. Table 4.11-6 shows the results of the stop
signals.
6
Note: Following the generation of a control command by the control logic, if the control
command fails to initiate the operation of a device, the control logic determines
that the control command has failed. The control logic will generate signals in
order to express “Control failure”.
When a stop command is generated during the selection of Device #3, the control logic
will clear the operation if the control logic can determine that the operation of Device #3 is
complete. Figure 4.11-3 shows that Device #3 unable to operate following reception of the stop
command.

The operating state turns to OFF, when the operation of Device#3 finishes
following the reception of a stop command from the ASEQ01 function.

The ASEQ01 function generates a select signal for stopping the control logic.

The ASEQ01 function generates an operate signal for stopping the control logic.

The operation of Device#3 failed.

the operation of Device#3
Figure 4.11-4 depicts the operating sequence when an emergency command is input; the
control logic will cancel the operation in accordance with the execution state given from a
device. If the operation signal is not controlling the device, the control logic will clear the
operation promptly. If the operation signal is controlling the device, the control logic will clear
the operation when the control logic function can determine that the operation of the device is
complete, in this case Device#1.
