Field Wiring
Terminations for field wiring are integral to each I⁄O module baseplate.
Programming Workstation
TriStation 1131 is a programmer’s workbench for developing, testing, and
documenting process-control applications that execute in a controller. TriStation
runs on a Windows NT
®
PC.
After an application is developed, a download operation installs the
TriStation 1131 project in a controller and verifies that it is operating correctly. For
more information, see the TriStation 1131 Developer’s Guide.
Programming Languages
TriStation supports the following three programming languages that comply with
the IEC 61131-3 International Standard on Programming Languages for
Programmable Controllers and reflect the guidelines documented in the IEC 65A
Type 3 Report:
• Function Block Diagram (FBD)
• Ladder Diagram (LD)
• Structured Text (ST)
A fourth language, Cause and Effect Matrix Programming Language Editor
(CEMPLE), automates the implementation of CEM methodology.
