The FBM228 enables the control station to access any block parameter device in any H1. With the FOUNDATION fieldbus block, the parameters in the H1 device are dynamically updated in the control station memory and can be connected to all other blocks in the station, allowing easy construction of control loop function modules and control station modules containing the H1.
With the FBM228 and Foxboro DCS control software, for every control loop you have
Selection of PID blocks to locate in field devices or host control stations.
Complex strategies can be subdivided so that faster secondary loops, PID and AO device blocks composed of AI run in the field, while complex blocks such as the main PID loop run in the host system.
The FBM228 also supports enhanced DCI block sets, making it possible to control station access to block parameters in H1 devices. The offset of the specified parameter. Subindexes are parameters in resource, sensor, and function blocks.
For example, these DCI blocks can be used to obtain device diagnostic information for developing maintenance and alarm policies.
These modules include:
BIN indicates binary input
●IN represents an integer value
●RIN is a real input
● The actual output route
•PAKIN is used for bit enumeration arguments
•string Used for string data
The FBM228 is electrically compatible with standard HART signals.
peculiarity
● Comply with the Foundation Fieldbus specification and support all Foundation Fieldbus H1 field devices (ITK) 4.6 or higher registered to the Interoperability Test Kit.
Provides support for standard FF views 1, 2, and 4, including policies that represent dynamic block parameter control station configurations that can be used as connectable values in control.
Provides parameters in field devices for all applications that operate on control core service workstation access.
Make the development of integrated control database seamlessly connect H1 function block and control station function block. Database is the use of graphical control strategy diagram to build the Foxboro DCS control system editor.
● Support host control and field loop control. Can be installed as a redundant pair to provide maximum uptime, complete redundant communication between the FBM228 and fault tolerant control
