Description of SipPS2PA
Object name (type + number) and family
Type + number: FB 2642
Family: Sipart
Application area of SipPS2PA
The block is used for the following applications:
● Control of a Sipart PS2 PA with Profibus PA I/O
● Control of an optional auxiliary valve for regulating the auxiliary power of the control valve
How it works
The Sipart PS2 PA is brought to a specified position using an analog activation signal.
The block forms the manipulated variable error from the difference between the activation
signal and the acquired position feedback and can monitor it for adherence to high and low
limits.
The control valve is monitored for the "Open"/"Closed" position. The block can be connected
with a digital limit switch for this purpose. The block can generate the digital position signals
itself through the adjustable limits for the "Open"/"Closed" position.
Missing feedback can be derived from the control in the block.
Various inputs are available for control purposes. The next chapters provide more detailed
information on configuration, operating principles, visualization and operation.
Configuration
Use the CFC editor to install the block in a cyclic interrupt OB (OB30 to OB38). The block is also
installed automatically in the startup OB (OB100).
The SITRANS Library contains templates for process tag types as examples with various
application scenarios for the SipPS2PA block.
Examples of process tag types:
● I/O via Profibus PA (SIPART PS2 Profibus PA)
The templates are described in more detail in Template of SipPS2PA (Page 302).
