The operation state turns to OFF, when the control logic cancels the
selection of Device#1 following the reception of a stop command from
the ASEQ01 function.

1
The ASEQ01 function generates a selection signal for
the emergency stop for the control logic.
*
2
The ASEQ01 function generates an emergency
command for the control logic.
*
3
The control logic turns the selection
signal to OFF when the control signal is
not sent for the device.

4.11.4 Control hierarchy conditions
The user should program the “Control hierarchy” for the ASEQ01 function. The user should
connect the condition with the select condition logic using the connection point
“ASEQ01IN_TMP_28”. For more information, see Chapter
Control and monitoring application:
Control hierarchy
. Table 4.11-8 shows the respective points in the ASEQ functions.

4.11.5 Input for emergency stop
The ASEQ functions are able to receive an “EMERSTOP_EXEC_STOP” command (see Table
4.11-3); the user should program to acquire the sign so that the ASEQ logics can abandon for
controlling devices. The operation will stop instantly even if the control logic is waiting for
some condition (i.e., synchronization or others).
