Application Builder
INTRODUCTION
1.3.2 System Requirements
The computer used to run the Application Builder requires an 80286 or greater
processor (80386 or greater is recommended for speed) with IBM PC AT
compatibility. The computer must be equipped with the following components
to run the software.
• A Hard Disk Drive with at least 10 megabytes available hard disk space.
• A 3.5-inch Flexible Disk Drive (high density 1.44 MB)
• 4 megabytes of RAM. All RAM above the first megabyte must be
configured as extended memory.
• Two Serial Communication Ports (COM1, COM2, COM3, or COM4)
• A Color Display (VGA, SVGA)
• A keyboard and mouse (two or three button)
• DOS Version 3.3 or higher.
• A Math Coprocessor is recommended but not required.
A printer (Section 4.14.4) is required to perform utilities such as making a hard
copy record of the data base.
1.3.3 Communication Requirements
The Application Builder requires a communication link for ICN communications
or a RS-232 or RS-485 interface for Extended Modbus communications to
import, download or check the status of a data base.
The Instrument Communications Network (ICN) interface between the computer
and the instruments can have as many as eight ICNs connected to the
computer via the 1720N Communication Link. One or two ICNs may be
connected using the 1731N Mini Link Board for AT Style PCs or the 1733N Mini
Link External. The 1720N Communication Link is connected to the computer
via an RS-232C serial port.
RS-232 is implemented when the distance between devices is 50 ft (15 m) or
less. RS-422 or RS-485 is used when the distance between devices is greater
than 50 ft (15 m) up to a maximum distance of 4000 ft (1200 m).
