Device Description; Configuration Of The Indicator And Ff; Functions - Endress+Hauser RID14 Anleitung

RID14
For control tasks there are the blocks:
• PD controller or
• PID controller
More information on this can be found from Section 11 onwards.
In the field indicator, the following function blocks are available:
• Input selector
• PID
• Integrator
• Arithmetic
6.3.6 Fieldbus based process control
With the FOUNDATION Fieldbus™ field devices can carry out simple process control functions
themselves, thereby relieving pressure on the superior process control system. Here the Link
Active Scheduler (LAS) coordinates data exchange between the sensor and controller and
makes sure that two field devices cannot access the bus at the same time. To do this,
configuration software such as the NI-FBUS Configurator from National Instruments is used to
connect the various function blocks to the desired control strategy – generally graphically.

6.3.7 Device description

For commissioning, diagnosis and configuration, make sure that process control systems or
superior configuration systems can access all device data and that the operating structure is
uniform.
The device-specific information required for this is stored as so-called device description data in
special files (the 'Device Description'- DD). This enables the device data to be interpreted and
shown via the configuration program. The DD is thus a kind of 'device driver'.
On the other hand, a CFF file (CFF = Common File Format) is required for the network
configuration in the OFF-line mode.
These files can be acquired as follows:
– Free of charge via the Internet: www.endress.com
– Via the Fieldbus Foundation Organization: www.fieldbus.org

Configuration of the indicator and FF

functions

The FF communication system will only function properly if correctly configured. You can obtain
special configuration and operating programs from various manufacturers for the
configuration.
