Introduction
The Tempress Systems, Inc. process controller, DPC, has some unique features that enable the user
to program any kind of process recipe in any way possible.
A process recipe is made of steps, and within one step several commands can be programmed.
The DPC is designed to execute commands in one particular step simultaneously. The sequence of
commands is therefor not important (except for “Branch on” and “Abort on “ alarm commands).
It is recommended, though, to use a consequent sequence to improve readability for the user.

6 steps to a process recipe
3.1.2.1 Step 1: Determine the required process temperature
The first step is to define the required process temperatures. These include the Load/Unload
temperature and the Process temperature(s).
Settings that need to be determined are the setpoint, the slope, the Hi and Low limits and the type
of temperature control (spike or paddle).
3.1.2.2 Step 2: Program the temperatures
The temperatures must be programmed in the DTC memory either using a touchscreen or using
the TSC-2 computer(s).
