Panel Software Support
Overview The Compact Controllers may be configured, I/O Mapped, and programmed using
Concept panel software, full-feature Modsoft panel software, or Modsoft Lite
(depending upon the model).
All of these software packages can be installed on the Modicon P230, an IBM-AT,
or a compatible computer. The programming and configuration editors used for
Compact are similar to those used for other 984s; special I/O Map screens have
been designed for A120 I/O modules.
Concept
(E984-258/265/
275/285 Only)
Concept may be used with the E984-258/265/275/285 models.
Concept contains Function Block Diagram (FBD) and Sequential Function Chart
(SFC) programming languages as well as a subset of data types of the international
IEC 1131-3 norm.
Concept includes the following features:
FBD depicts process data flow for both discrete and continuous control
applications.
SFC provides a graphical representation of the process.
EFB is a "C" toolkit that allows you to create custom function blocks.
Structured Text is ideal for implementing complex equations.
Ladder Diagram (ladder logic) complies with the IEC 1131-3 ladder diagram
specification.
LL984, inside Concept, provides the same tools as Modsoft 984 ladder logic.
Concept operates with Windows 98, Windows NT, or Windows 2000. The E984-258/
265/275/285 models are supported by the following two Concept software
packages: Concept M (372 SPU 472 01 V25) and Concept XL (372 SPU 474 01
V25).
Note: You must use Concept 2.1 or higher with the E984-258/265/275/285 models;
Modsoft does not support these models. For a detailed description of Concept and
its operations, see the Concept User Manual (840 USE 493 0x).
