State Logic Processor Description

The State Logic Processor (SLP) is a module which inserts into a Series 90t-30 PLC chas- sis. This module has the State Engine operating system to execute State Logic control programs produced by the ECLiPS programming software package.

The SLP exists together with a CPU module in the Series 90 -30 PLCs. The CPU must be a model 331, Revision 3.03 or higher. The CPU may execute a Relay Ladder Logic Pro- gram at the same time the State Logic Processor is executing a State Logic Program. The SLP manipulates the CPU memory space and the CPU controls the I/O during its normal cycle of operations. More than one SLP can be installed in one Series 90-30 PLC system, although the SLP must be installed in the main rack with the CPU.

The software products, ECLiPS and OnTOP, are the user interfaces to the SLP. ECLiPS is a program development and on-line monitoring software product which runs on an IBM-PC compatible computer. OnTOP, the On-Line Troubleshooting Operator Pro- gram, also runs on an IBM-PC compatible computer. For questions about programming or on-line functions, see the ECLiPS or OnTOP User's Manuals.
