Siemens Open Library
The Siemens Open Library was developed by DMC, Inc. over several years. Through a joint collaboration with Siemens Industry, DMC documented the library and released it as an Open Source Library open for anyone to use and distribute. The Library is Open Source and will allow for users to contribute content to help enhance the overall availability of functionality to the greater Siemens User Community.
This library is targeted at S7-1200 and S7-1500 applications using a Siemens Comfort Panel or WinCC Advanced RT. Special changes have been made to accommodate S7-300 and S7-400 processors. The Version of Portal used for initial development was V13 SP1, however, additional updates will continue to be made.
1.Library Contents:
| Code: | The Siemens Open Library contains many components to assist with development. The library contains the following items:
Documentation for all objects with examples of configuration
Example project to demonstrate the use of all library objects
Library Objects
Function Block for PLC functionality
HMI User Defined Type for quick mapping of many variables to the HMI
Error User Defined Type for automatic generation of numeroase alarm messages
HMI Icon Faceplate for an overview of object status
HMI Pop-up Faceplate for detailed control and object status
Excel Macro used to automatically generate alarms
|
2. Library Overview
| Code: | This section outlines all objects that the library currently contains.
Motor Control
G Series VFD Control – fbVFD_GSeries
The G Series VFD Control Function Block is utilized for use of Siemens G Series VFD or Micromaster VFDs using Standard Telegram 1. This block does not use a technology object. This allows for a lower CPU requirement for each drive. It utilizes Standard Telegram 1 and has been tested on a G120, however, it will function with any drive using Standard Telegram 1 on either Profibus or Profinet.
Analog VFD Control – fbVFD_Analog
The fbVFD_Analog Motor Control Function Block is utilized for use of a VFD controlled with digital and analog signals. The error UDT is kept identical to the GSeries error UDT, however, some error outputs are not utilized by this block.
Digital Single Speed Motor – fbMotor_Reversing
The Reversing Motor Control Function Block is utilized for motors started and stopped using digital outputs. This block functions with single direction or reversing motors.
Valve Control
Two State Solenoid Valve – fbValve_Solenoid
This library item is to be utilized with two state solenoid valve applications. It can be used for spring close, spring open, or double acting solenoids.
Analog Valve – fbValve_Analog
This library item is to be utilized with a valve controlled using an analog output. This block will work with any valve that is controlled through an analog output from the PLC.
Inputs/Outputs
Analog Input with Scaling and Alarms – fbIO_AnalogInput
This library object scales analog inputs and provides setups for alarms.
Analog Output with Scaling – fbIO_AnalogOutput
This library object scales process values to be used for Analog Outputs.
General
System Control
This library object is a User Defined Type only that is used to provide mode information to other Library Objects, and is controlled by HMI Faceplates.
Interlock Function Block – fbInterlock
This library object is used to provide operator information for multiple values that are interlocking a process. It has inputs for items that may be interlocking a process, and informs the operator of what interlocks are preventing operation via an HMI faceplate.
PID Interface – fbPID_CompactInterface
The S7-1200 and S7-1500 provide PID Technology objects that are best practices for use, therefore this would not replace those blocks, but would provide an interface to the technology object on the HMI.
The interface will allow for modification of the PID loop and for manual override of the output from the HMI.
Unlike other library objects that are fully encapsulated, many of the outputs of this block will need to be mapped to the PID_Compact block.
Standard Alarm Interface – fbAlarmWarning
The Standard Alarm Interface provides an easy way to setup additional alarms.
