Automatic sequence control function (ASEQ)
The function of the automatic sequence controller (ASEQ) is to control the PLC function that
is used within the automatic sequence control function, which can be coded by the user. This
control logic has software signals; the status of these software signals are changed by control
commands that are sent from upstream devices. One of the upstream devices is a SAS server.
Another is the front panel of the IED, which means that the user can operate the device locally
using the ASEQ function. The ASEQ function is divided into a couple parts, these are referred
to as “ASEQ01 etc.” functions (i.e., ASEQ01, ASEQ02 and others). Therefore, some PLC
functions are controlled by the ASEQ functions at the same time. For simplicity, only the
ASEQ01 function is discussed here, the features in the other ASEQ02 etc. functions are
identical to the ASEQ01 function.

Note: The implementation of such features is dependent upon the selection of hardware and
the configuration of functions. Several IED models do not support certain features. To
determine whether a particular feature has been implemented within an IED, identify the IED
ordering number; and check the order number for the “G&T position” referring to the
comparison table below. For more information, see
