TASK

Based on the recipe in the chapter 'Process Description’ we are setting up and programming an SFC step sequence.

For this chapter, we reduced the recipe to the following sequence:

1.First, 350ml are to be drained from educt tank =SCE.A1.T1-B003 to reactor =SCE.A1.T2-R001.

2.When reactor =SCE.A1.T2-R001 is filled, the liquid it contains is to be heated to 25°C and the stirrer is to be switched on.

3.When the temperature of the liquid in reactor =SCE.A1.T2-R001 has reached 25°C, this liquid in this reactor =SCE.A1.T2-R001 is to be stirred another 10 seconds at 25°C.

4.Now, the liquid in reactor =SCE.A1.T2-R001 is to be heated to 28°C with the stirrer being switched on.

5.When the temperature of the liquid in reactor =SCE.A1.T2-R001 has reached 28°C, this liquid is then to be drained into product tank =SCE.A1.T3-B001.

OBJECTIVE

In this chapter, the student learns the following:

–Setting up and editing SFC step sequences

–Establishing logic operations between SFC step sequences and CFCs

–Establishing logic operations between SFC step sequences and the operands in the symbol table

–Testing sequence step programs
