Bristol® ControlWave® LP

Communication Protocols

Like all Emerson products, ControlWave supports BSAP (Bristol Standard Asynchronous Protocol), Modbus, DF1 and serial ASCII as standard func- tions. These protocols are implemented in flash- ware so no additional hardware is required to use any one or a combination of all protocols.

All of Emerson’s Bristol Network 3000 and ControlWave RTU and controller products support BSAP protocol. BSAP is widely accepted as provid- ing exceptional data integrity and greatly simpli- fies communication between controllers. BSAP is provided with interfaces for Master/Slave, vertical networks and Client/Server, horizontal networks. In either case, variable lists are created in each con- troller that are easily passed from server to client or slave to master.

BSAP meets the definition of an industry-standard, open-architecture protocol because if conforms to ISO standards 2629, 1745 and 2111, it is not propri- etary in that Emerson does not charge a license fee and makes the protocol and documentation avail- able to anyone.

While BSAP is an open protocol, the added func- tionality of the messages passed provide much more capability than is found other networks.

•Global time-synchronization

•Time-stamped Alarm reporting

•Historical archive data transfer

Slave, Serial and TCP/IP Open Modbus. In addi- tion there are consideration regarding supported function codes, floating point values and byte order. Emerson’s Bristol products supports the following:

•Modbus serial and TCP/IP Open Modbus (Ethernet)

•Master and Slave

•Modbus RTU and ASCII

•Modes 1 - 7, 8, 15 & 16

•IP modes 51, 52 & 53

•Integer and IEEE 4 byte floating point

DF-1 protocol is the primary mechanism to inter- face to Allen Bradley PLCs and interface devices. ControlWave and Network 3000 both support DF-1 half-duplex master protocol.

Generic Serial Protocol

The Generic Serial Protocol is a Master and Slave protocol used to send and receive messages typi- cally with third party serial ASCII devices. This protocol can be used to interface with such devices and message boards, card readers and many mea- surement devices.

•Audit file transfer

•On-line program editing

•Diagnostics

•Communication statistics

Modbus - Modbus is often considered a de-facto standard protocol because broad usage as ei- ther the primary or a secondary offering in many measurement and control related products. Even with its common use, Modbus protocol actually has many variations. Consider Modbus RTU and Modbus ASCII, Master &

Multi-User Security Access

Security is an essential element of any open system, particularly those with Internet access. ControlWave employs a User Name/Password ac- cess system protected by a 56-bit encryption tech- nique through the TCP connection. There can be up to thirty-two users, who sign-in using their name and password. Both the name and the password can be up to sixteen characters.
