The M1594A Redundant I/O Ethernet Link Module designed specifically for redundant remote I/O and control applications, where high availability is required in hot standby configurations. It is used in conjunction with the M1267B (P3e-R) CPU module

The M1594A Redundant I/O Ethernet Link (RIOe) Module is designed specifically for redundant I/O and control applications, where high availability is required in hot standby configurations.

A high availability system is constructed by combining two additional identical specialised redundant P3e-R CPUs, each with their own Power Supply and Base and this M1594A Redundant I/O (RIOe) Module, to create independent Primary and Secondary Master Controllers. These two Master Controllers are connected to up to seven common Remote I/O Bases through this RIOe module and a Maxiflex M1262F Remote I/O Processor on each I/O Base using Ethernet and to the SCADA system to create a hot standby controller configuration with common I/O.

The Primary and Secondary Controllers in a hot standby system are synchronised every program scan, so that should the primary Controller fail, the secondary Controller can automatically continue program operation from the last Primary Controller scan.

All local data is accessible from a SCADA system through up to 65,500 Data Interchange Registers in a single “Data Interchange Table (DIT)” for ease of communications.

All system configuration data and dynamic data can be read and written through this convenient table interface.

This M1594A RIOe module fits in Slot 1 of both the Maxiflex Master and Secondary Controllers’ Master Bases.  Each Remote I/O Processor can scan up to 15 I/O modules.

This RIOe module scans the I/O from the remote bases and transfers the I/O data into the P3e-R CPU’s Data Interchange Table for program or SCADA access.
