Siemens Module B3 manual Solution of the PLC program

Page 58

Automation and Drives - SCE

Solution of the PLC program:

Network 1: Call PID Controller

Wiring the manual value to thevalue 0 or 100% of the manipulated value

(Refer to NW 2 and NW 3)

Network 2: Default Manipulated value 100%

Network 3: Default Manipulated value 0%
