State Logic Products
State Logic Overview
State Logic, unlike other Series 90-30 PLC systems, does not use ladder logic type instructions.
Instead, it uses ”Natural Language” programming instructions. For example, to program a rung of
logic that turns on a motor at a specific time in a State Logic system, you could create a statement,
“If hour is past 8 AM, start the exhaust system.” This type of programming instruction cannot be
handled currently by standard Series 90-30 CPUs, so a State Logic CPU is required. This chapter
only provides an overview of State Logic products. For details, please see

State Logic Products
The State Logic product line consist of just a few key hardware and software items. To complete a
State Logic system, standard Series 90-30 products are used. The primary State Logic products
are:
■ State Logic CPUs. There are five models: 311, 313, 323, 331, and 340.
■ State Logic Processor Module (IC693SLP300). This module can reside in a Series 90-30
PLC system containing a standard CPU, providing the user with both standard ladder logic and
State Logic capabilities.
■ Serial Communications Module (AD693CMM301). Provides two additional serial ports for
the State Logic system. Requires a 331 or 340 State Logic CPU.
■ ECLiPS software. Provides Natural Language programming and online debugging functions.
■ OnTOP software. A debugging tool, it provides operator interface, maintenance, or
troubleshooting functions. It has all the capabilities of the ECLiPS debugging function.
Baseplates and Power Supply, I/O, and Option Modules
The State Logic CPUs and modules work with most standard Series 90-30 baseplates, power
supplies, input and output modules (discrete and analog), and option modules. Please see
GFK-1056
, Series 90-30 State Logic Control System User’s Manual,
for details.
