4.11.1 Function setup
Figure 4.11-1 outlines the command reception in the ASEQ01 function. The ASEQ01 function
can generate a start command at the PLC monitoring point “ASEQ01_EXEC_START” (see
Table 4.11-5), when the start command is provided for the ‘ASEQ01_CONTROL_REQ’.
Similarly, when a stop command is received in the ASEQ01 function, the stop command will
be generated at the PLC monitoring point “ASEQ01_EXEC_STOP” (see Table 4.11-6) †.
†Note: Create “IN1” and “IN2”points in the user programming logic; make the connection
between the ASEQ01 function and the user programing logic. Refer to chapter
PLC function
. The user-programming logic is also required to have output points.
For example, if the user wishes to control a CB using the logic, the logic should
have two output points for two binary output circuits (BOs). Figure 4.11-1 shows
how two BOs are used for CB closing and CB opening.
‡Note: The ASEQ01 function does not have the responsibility to restart the programmed
logic after an emergency stop signal has been applied. Therefore, the user should
program the logic to generate an operation result signal in case of the emergency
stop signal being applied in the logic. See section 4.11.5 for the emergency
operation.
‡Note: PLC connection point “ASEQ01_EXEC_RESET” is provided for stopping the
ASEQ01 operation, as shown in Table 4.11-4.
