GPIB Resources for TestEquity Chambers

See the complete TestEquity Environmental Chamber product line HERE >>

GPIB communications is achieved through an ICS Electronics GPIB-to-Modbus Interface Converter which has been specifically designed to work with the Watlow F4 controller used on TestEquity chambers. The converter lets you send simple read-write messages over GPIB to control and query the chamber's controller. The converter does all of the Modbus RTU packet formatting and handles the response packets.

LabVIEW Drivers
LabVIEW-GPIB.zip (442K) is written by ICS Electronics. Includes executable VI Front Panel examples and a Driver Library file for all VIs.

Visual Basic Programming
ICS has a Temperature Control example program written in Visual Basic for its GPIB-to-Modbus Interface. Application Bulletin AB48-25d (pdf, 441K) describes how to use the program and how to adapt the program to a final application or to other GPIB Controller cards. The Application Bulletin includes a description of a Visual Basic example program that controls process temperatures with the temperature controller. The program runs on any GPIB Controller Card that uses the NI488.2 Command set. File VB5_TempCtlr.zip (75K) contains the Visual Basic source and executable files.

NOTE: The examples shown in documentation from ICS are for illustration purposes only. They may not represent the correct setup or configuration for TestEquity chambers. Sample programs from ICS may change critical setup parameters, resulting in improper chamber operation. They are provided as a guideline for how to write your own programs only. Correct setup parameters are documented in the TestEquity chamber manuals.
