Bristol Babcock’s 33XX DPCs BSAP Serial Slave Communication Module

Description

Bristol Babcock Serial Slave Module

The MVI56 Bristol Babcock Serial Slave Module allows Rockwell Automation ControlLogix I/O compatible processors to interface easily with Bristol Babcock Serial communication devices.

 

Features and Benefits

The MVI56-BSAPS module acts as an input/output module between the BSAP network and the Rockwell Automation backplane. The module acts as a slave receiving commands from a BSAP master device. The data transfer from the ControlLogix processor is asynchronous from the actions on the BSAP network. An internal database in the module exchanges data between the processor and the BSAP network.

BSAP operates in a polled environment. Each link in the network supports a different poll rate. The rate selected depends on a variety of application-dependent factors.

BSAP has been designed and implemented according to the functional layers of the International Standards Organization (ISO) model. Because each layer is independent of its adjacent layers, both synchronous and asynchronous transmission modes can be supported.

The Bristol Babcock Synchronous/Asynchronous Communication Protocol (BSAP) is used process control applications in the energy, water and wastewater industries.

Typical industrial sectors include:

• Security monitoring
• Pump and lift station control for water & wastewater 
market
• Flow measurement and metering station control for 
the natural gas market.

 

Specifications

• Single Slot – 1756 backplane compatible
• The module is recognized as an Input/Output module and has access to processor memory for data transfer between processor and module
• Ladder Logic is used for data transfer between module and processor. Sample ladder file included.
• Configuration data obtained from configuration text file downloaded to module. (Sample configuration file
• included
)
• Local or remote rack

 

Functional Specifications

The Bristol Babcock Synchronous/Asynchronous Communication Protocol (BSAP) is the foundation for a proprietary network that has a tree-structured topology. This open-ended topology supports a variety of configurations which may include one or more nodes at each of up to six levels. Messages can be sent between nodes on the same level or on different levels. Messages can be sent between nodes (local message only). Each message is uniquely identified and has an error-checking code associated with it.

Some of the general specifications include:

• Slave implementation
• Support for the storage and transfer of internal database registers to/from the ControlLogix processor’s controller tags
• Two ports to emulate a BSAP slave RTU
• Peer-to-Peer communication for Local BSAP formatted messages – slave to master only.
