Chapter Three - Getting Started
Introduction
First-Time Configuration
Communication Ports
Device Configuration
DDE Server User's Guide
In this chapter, we'll explain how to configure the PMCS DDE Server for use:
starting the software, understanding what's on the screen, setting it up for
communications, and telling it what devices are connected and how to communicate
with them.
This chapter is a functional tutorial rather than a comprehensive reference. Chapter 4,
Menus and Toolbars, provides in-depth descriptions of the menus and each function
available.
This manual also assumes that the hardware side of the PMCS network has been set
up and wired correctly, and that the host PC that PMCS will run on has been properly
connected to the network.
As we mentioned in Chapter 2, the PMCS DDE Server collects data from devices
connected across a network. We'll have to set up our Server to communicate
correctly with the network and recognize the devices we've attached.
First-time configuration involves two basic procedures: setting up communication
ports and then configuring devices. We'll provide examples of each procedure.
You must identify the communication settings for each of the Server's
communication ports: baud rates, parity, stop bits, etc. This permits the Server to
communicate correctly with the attached networks. (Note for Ethernet users:
configuration of Ethernet communications is slightly different and will be covered
later in the document.)
Here you'll be telling the PMCS DDE Server the specific devices that are connected
to the network by defining topics for the Server to look at. A topic consists of a
device name, the number of the communication port the device is connected to, the
Modbus address of the device, the device type, and related scan-interval information.
