Modicon M580 Safety as Safety Instrumented System (SIS)

Modicon M580 as Basic Process Control System (BPCS)

This architecture is based on a Modicon M580 Safety PAC 1 monitoring Safety Instrumented Functions with Modicon X80 Safety I/O 4 and a Modicon M580 PAC 2 operating the Process with Modicon X80 5 and STB 6 I/O. Both PAC are engineered with EcoStruxure Control Expert 3 . The Modicon M580 Safety PAC inherits all the Modicon M580 characteristics in term of features, performance, and architecture. This Integrated solution in most useful for medium to large architecture, or if a physical separation is required in between the Basic Process Control System (BPCS) and the Safety Integrity System (SIS).

Integrated Safety architecture

Common Safety This architecture is based on a single Modicon M580 Safety PAC 1 monitoring Safety Instrumented Functions with Modicon X80 Safety I/O 2 and operating the process with Modicon X80 4 and STB 5 I/O. The same PAC is managing both Process and Safety. Logics are separated but integrated in the same EcoStruxure Control Expert application 3 . This Common Safety solution in most useful for small to medium architecture. In this case the Basic Process Control System and the Safety Integrity System are integrated in the same hardware but independent from each other. The non-safety related Modicon X80 I/O modules as the DIO islands are classified as non interfering with Safety.

Common Safety architecture

High-availability Safety The Modicon M580 Safety PAC can be used in standard or high-availability architectures using respectively standalone or redundant controllers (Hot Standby system). The high-availability architecture provides the same reliability level (SIL3) as the single architecture and provides features for critical processes to configure with EcoStruxure Control Expert 3 . To increase availability, the Modicon PAC allows to use in a simple way: b Redundant processors, named “Primary CPU” 1 and “Standby CPU” 2 b Redundant Power Supply 4 b Ethernet ring network topology 8 The ring can be made of copper 8 and optical fiber links 7 with using Modicon switches 5 and Modicon X80 optical converters 6 . Primary and Standby CPU racks do not support Modicon X80 I/O but only communication modules as for example 9 with Remote Terminal Unit ( BMENOR2200H ) and 10 with the control network ( BMENOC03 p 1 ). Other types of communication modules may be used for OPC UA ( BMENUA0100 ), IEC61850 ( BMENOP0300 ), PROFIBUS DP ( PMEPXM0100 ) communication.
