Driver blocks

The gas analyzers are integrated into the hardware configuration of the SIMATIC PCS 7 process control system using their GSD files. Parameterization of the driver blocks is subsequently carried out corresponding to the device configuration. The driver blocks provide the following functions:

• Reading of analyzer values
• Starting of autocalibration
• Evaluation of device-specific diagnostics
• Standard diagnostics
• Alarms for analyzer values (alarm limits adjustable on the block)
• Simulation

Symbols and faceplates

The symbols are automatically created and interlinked by the wizard "Generate block symbols". The faceplates can be displayed in various views:

• Standard
• Maintenance
• Configuration
• Limits
• Trend and alarm
