| Protocol: |
The Reliable Controls protocol is encapsulated
in an UDP datagram for transmission over Ethernet networks. The relevant,
readily available Internet standards are:
RFC 894. A Method for Transmission of IP Datagrams over Ethernet Networks.
RFC
791. Internet Protocol.RFC 768. User Datagram Protocol.
RFC 826. An Ethernet
Address Resolution Protocol.
RFC 792. Internet Control Message Protocol.
The data of the User Datagram consists of a Reliable Controls protocol header
followed by Reliable Controls data. The Reliable Controls port number used
in UDP is 524C hex. |

Introduction
|
| This document provides general information on the features
of the Reliable Controls Protocol supported by the RCP OPC Server. When
you install the OPC Server, you should also review the sections titled:
About the I/O Driver, How Do I.., Setting up The I/O Driver,
OPC Addressing and Using the PowerTool in the RCM electronic documentation. To get there,
click on Help and Help Topics on the PowerTool menu bar. The PowerTool
is a client application with a graphical user interface that accesses the
RCP OPC Server and lets you view and modify communications channel, device,
and datablock properties. |
| |
| Features
|
| RCP Includes the following Features
|
| |
|
Feature |
Feature Description |
|
1 |
PowerTool - OPC server has a user interface called the PowerTool for
configuring channels, devices, and datablocks. It also provides statistical
communications data at each level. |
|
2 |
Built-in datascope for checking Host-to-RTU communications. Can write
messages to disk for later analysis. |
|
3 |
PowerTool has context sensitive help. |
|
4 |
Direct, Radio, and Telephone communication modes. |
|
5 |
Server automatically reads after a write to confirm the
write. |
|
6 |
Server supports the Dynamic protocol General Network
Addressing Mode (GNAM) and the Restricted Network Addressing Mode (RNAM). |
|
7 |
Automation Interface - You don't have to use the Power
Tool to configure the driver. You can make your own COM or OLE application
(such as Microsoft's Visual Basic) to configure the driver and access
data. |
|
8 |
Secondary Poll Rate - The OPC Server polls a datablock
at the secondary poll rate once the Access Time expires. Data is polled at
the secondary poll rate until there is another client request for data. If
the secondary poll rate is set for a longer period of time than the
Primary Rate, CPU resources are reduced while ensuring that the datablock
will always be polled. |
|
9 |
Phased Poll Rates |
|
10 |
You can Enable/Disable individual communication
channels, devices, and datablocks from the automation interface or your
HMI. |
| |
| Device Commands Supported
|
| The device READ/WRITE commands supported are shown in Table
1. They are described in reference to the command code defined by the protocol.
Refer to the Reliable Controls Protocol and Reference Guide, Revised: July
13, 2003, Section 6. |
