How is the interface organized?

Project tree on the left navigates tag database, protocol drivers, IEC 61131-3 programs, HMI pages, and system configuration. Each opens in a central editor panel.

Live connection to a running RTAC showing real-time tag values, protocol status, and diagnostics without needing to redeploy.

ACSELERATOR RTAC Interface Overview

Quick Answer

acSELerator RTAC integrates a tag processor, multi-protocol driver configurator, and IEC 61131-3 editors (ST, Ladder, CFC) in one environment. Optional HMI screens are built in Diagram Builder (SEL-5035). The project tree on the left navigates between functional areas; the central panel displays the active editor.

Tag Database Editor

Tag list with properties — name, type, description, scaling, quality. Tag aliasing and cross-referencing across the project.

Protocol Drivers

Add and configure client drivers (polling devices) and server drivers (serving data to SCADA). Each driver type has its own configuration panel.

IEC 61131-3 Editor

Language selection (LD, ST, or Continuous Function Chart/CFC — not SFC), task and program organization, function block library browser, compile and deploy. Optional HMI uses Diagram Builder (SEL-5035).

Online Mode

Connect live to a running RTAC — view live tag values, force tags for testing, monitor protocol driver status, and view the event log.
