Getting Started

Aims
Based on the following simple example, "zEn01_13_STEP7__PID-Temp -> Pulse
Controller", you will learn to control the simulated temperature process with the
FB58 "TCONT_CP" temperature controller and to obtain the PID controller
parameters online.
Requirements
The following requirements must be met:
•
You are using an S7-300/400 station consisting of a power supply and a CPU.
•
STEP 7 (≥ V5.1 SP3) is installed on your programming device.
•
The programming device is connected to the CPU.
Creating a new Project and Copying the Example
Step Activity
1 Create a project in the SIMATIC Manager
with File->New...
2 Insert a SIMATIC 300 or 400 station to match
your hardware configuration.
3 Configure your station in HW Config and set
the cycle time of the cyclic interrupt priority
class of OB35 to 20 ms.
4 Copy the pulse controller program from the
sample project zEn01_13_STEP7__PID-
Temp to your station.
5 Select your program and copy it to the CPU
with PLC -> Download.
