Product Brief - Model M1267B MX CPU P3e-R
Maxiflex CPU P3e-R Redundant Controller
Maxiflex P3e-R CPU with Serial Port, Program Port, Ethernet Port and Sync Link Port. Programmable in five ISaGRAF IEC61131 languages. Order M1831A programming cable if required. Note: This product has been superseded by Model M1267C due to the addition of support for the Time Sync Module plus software enhancements. The MAXIFLEX P3e-R CPU is designed specifically for redundant remote I/O and control applications, where high availability is required in hot standby configurations. A high availability system is constructed by combining two identical P3e-R CPU’s, each with their own Power Supply and Base, to create independent Primary and Secondary Master Controllers. These two Master Controllers are connected to up to either three common Remote I/O Bases through a M1593A Conet Remote I/O Network Interface Module on each of the Controllers to a M1249A Remote I/O Scanner on each of the Remote I/O Bases using Conet OR up to seven common Remote I/O Bases though Ethernet using a M1594A Redundant I/O Link Ethernet Network Interface Module on each of the Controllers to a M1262F CPU as a Remote I/O Scanner 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” for ease of communications. All system configuration data and dynamic data can be read and written through this convenient table interface. The P3e-R can be programmed in one or more of the standard IEC61131-3 programming languages using the Omniflex ISaGraf Programmer’s Workbench, although conventional remote I/O systems can be implemented without the need for any programming. The P3e-R CPU automatically identifies the presence of I/O modules and performs I/O scanning of these modules, making this data available in the Data Interchange Table without needing to write a line of code. Following the ISO OSI 7-layer model, this CPU includes a powerful inter-network routing capability for retrieving data from the corners of the factory in very large, geographically spread-out installations. This capability allows many dissimilar network types to be linked to create a seamless factory intranet, quite often without the need to lay special network cabling. Many other features such as a built-in real-time clock, battery backup for temporary dynamic data.
