The OMP-MODL operates in the field based on a program loaded into its memory
called a Program Net (Figure 7... -1). The Program Net provides instructions for the
OMP-MODL including which channels to sample, when to sample, how to process
the incoming signals, when to output alarms, and much more.
Development of a Program Net is done on a PC running HyperWare. After
development, the Program Net is uploaded directly to the OMP-MODL memory via a
serial communication link or indirectly via upload to a PCMCIA card. The PCMCIA
card can then be plugged into the OMP-MODL. Actual development of the Program
Net is performed in the H
YPER N ET W INDOW and the serial transfer of the Program
Net from the PC to the OMP-MODL (or to the PCMCIA card) is performed from
within the H
YPER C OMM W INDOW .
Program Nets are developed through the following sequence of steps:
♦
Create a new Program Net file for the connected OMP-MODL
(which automatically determines the installed hardware in the
connected OMP-MODL)
♦
Add desired functions to the Program Net by dragging various
icons onto the HyperNet workspace
♦
Add connections between icon terminals indicating signal flow
♦
Configure the various icon options (eg Celcius or Fahrenheit,
type of thermocouple, filtering, equations, etc)
♦
Configure the Global icon
♦
Save the Program Net and/or transfer it to a connected OMP-
MODL for execution.
This chapter describes the HyperNet development environment and provides
detailed instruction on constructing Program Nets. Detailed icon configuration
information is provided in the Master Icon Reference in Appendix A. For the
