Honeywell HC900 manual Available from Honeywell, Inter-Connection to Other Networks

Components and Architecture - Ethernet Devices/Considerations

HMI software available for use with the HC900 Controller includes, but is not necessarily limited to the packages whose descriptions follow.

•available from Honeywell

−PlantScape SCADA or Vista Software, which operates under Windows 2000 operating software, provides PC-based supervisory control and data acquisition. This package includes a large selection of standard operating display templates, which can reduce development time significantly. PlantScape includes a full graphic display development environment, enabling development of custom graphics that include animated responses to changing process conditions. A batch reporting option is available in release 400, which includes a standard template for creating batch reports.

−SpecView32 (SpecView Corporation)

•Other software (available from third-party sources)

The following software, which incorporates Modbus/TCP connectivity, is available from third-party sources:

−The Fix Family (Intellution Incorporated)

−Wonderware (Wonderware Corporation)

−Citect (CI Technologies)

−OPC server/client software (various; available from Kepware and others)

Note: The items in this list are not sold by Honeywell. They have not all been tested and certified by Honeywell, and are not necessarily recommended or endorsed by Honeywell for any specific use.

Inter-Connection to Other Networks

In many cases, an HC900 Controller application will include a single, free-standing controller that involves no connections via the Ethernet Open Connectivity network. In other cases, the HC900 Controller will be a member of a Local Area Network (LAN) as indicated in Figure 13. The HC900 controller LAN may be very simple, or it may include many devices in a complex and very sophisticated structure. In any case, it must always be regarded as a single, modular entity that can be protected from intrusion by any other networking device to which this LAN is connected.

Various types of networking devices that enable selective connection to other networks are available. A "Router" is commonly used for this purpose.

The feature that gives the Router its name is its ability to examine and "filter" message packets, permitting passage of wanted messages and denying passage of all others.

Many Routers have a secondary, but important feature in that they enable translation of IP addresses, which enables networks with dissimilar network IP addresses to communicate as though they were members of the same network. This feature is particularly useful when an HC900 Controller LAN is installed under "local addressing rules". That is, IP addressing can be assigned without approval of or conflict with world Internet governing bodies. Later, when connecting to networks with more stringent addressing requirements, it is necessary only to configure the Router with address mapping and connect it between the existing LAN and the other existing network.

Connections to other networks vary in purposes and methods; some of these are described below.
