ControlWave Open Network Connectivity

By embracing the open system network technolo- gies available through TCP/IP, Ethernet, OPC, and Microsoft DNA, as well as pseudo standards such as Modbus and Open Modbus, ControlWave can provide a total Process Automation Management Solution for in-plant LAN based networks and Wide Area Network SCADA systems.

With the exceptional connectivity provided by the ControlWave network, access to real-time data and operating conditions, historical data, maintenance and performance data are all available to the global network. ControlWave provides the needed informa- tion to the plant floor technician, operator, engineer, supervisor and corporate management, even exter- nal customers.

Communication Protocols

Like all of Emerson’s Bristol products, ControlWave supports BSAP (Bristol Standard Asynchronous Protocol), Modbus, DFI, CIP, DNP3, and serial ASCII as standard functions.

These protocols are implemented in Flashware so no additional hardware is required to use any one or a combination of all protocols.

BSAP Protocol

BSAP - 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 provide much more capa- bility than is found in other networks.

Modbus Protocol

Modbus - Modbus is often considered a de-facto standard protocol because of its broad usage as either 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 & Slave, Serial and TCP/IP Open Modbus. In addition there are considerations regarding supported function codes, floating point values and byte order. Bristol products support 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

Generic Serial Interface

The Generic Serial Interface is a user program- mable Master and Slave protocol used to send and receive messages typically with third party serial ASCII devices. This protocol can be used to inter- face with such devices and message boards, card readers and many measurement devices.
