    Currently the 386EX Protected Mode DPC 3330/DPC 3335 controllers with Ethernet hardware installed are the only Network 3000-series controllers which support the IP protocol. Bristol Babcock’s ControlWave controller also supports IP, however, ControlWave communications are not covered in this book.

If you want to use a mixture of older DOS-based ACCOL Tools with Open BSI 3.1 (or newer) you will need to use NetView, and then use the NETBCX utility to generate network files compatible with the DOS-based tools.

  • Page 13 (Other types of LANs may be supported in the future, however, Ethernet is currently the only choice available.) A Bristol Babcock network using only IP nodes does NOT follow a hierarchical structure. For certain applications, this is a significant advantage over BSAP, because all nodes in a given section of the network are essentially on the same level.

    To obtain this performance goal, however, the user must have an understanding of how Network 3000 communications work. We can think of the Network 3000 architecture as being made up of three major parts. These parts are the data link, the network routing information, and the applications which use the data link.

  • Page 19: Chapter 2 - Guidelines For Setting Up Bsap Networks

    What is BSAP? BSAP stands for Bristol Synchronous / Asynchronous Protocol. All ACCOL-based Network 3000-series controllers can communicate using BSAP. Each node (RTU) in a BSAP network is assigned a 7-bit local address (from 1 to 127) and a 15-bit global address, based on its location in the network. The local...
  • Page 20 If this BSAP network is a sub-network of an IP node, the Network Master would be the Network Host PC (NHP), and the IP node would be the only level 1 node.

  • Page 30: What Is A Network Host Pc (Nhp)

    What is A Network Host PC (NHP)? A Network Host PC is any Open BSI 3.0 (or newer) workstation. Typically, this workstation has some Network 3000-series remote process controllers (RTUs) connected to it (it serves as the ’host’ for those RTUs). Those RTUs must be defined in a Network Definition (NETDEF) File at this NHP.

To determine a minimum value for this number, find the longest Master Port poll period for each level of the network (including the Network Master level.) The “RTU Message Timeout”...
