The series can be configured as a single set point controller (static
mode) or a ramp and dwell profiling controller (profile mode). The
profile mode feature allows the user to program up to 9 profiles of
up to 64 free-format (ramp, dwell, jump or end) segments each. The
total segments available for the product is 288 segments.
The profiling controllers contain the following features:

Flexible Configuration of Program

Flexible Configuration of Program

There are up to 64 segments can be defined for a profile. Each
segment can be configured as a ramp or a dwell (soak) segment or
defining a repeat number of cycles at arbitray location within the profile
and finally terminated by an end segment.The user can edit a currently
running profile.

Maximum Capacity of Program

Maximum Capacity of Program

There are at most 9 profiles can be defined and 288 segments totally
available for all profiles. The profiles are divide into three kinds of length.
The short length profile contains 16 segments, the medium length profile
contains 32 segments while the long length profile contains 64 segments
at most.

Event Input

Event Input

The event input feature allows the user to select one of eight functions:
enter profile run mode, enter profile hold mode, abort profile mode,
enter manual mode, perform failure transfer, enter off mode, advance
to the next segment and select second set of PID values.
