ABB AC800M 3BSE053240R1 PM891
The PM891 processor is a single chip unit with a power supply, CPU board, and unit terminal. The device includes a microprocessor and RAM memory, real-time clock, LED indicator, INIT button, and secure digital interface. The PM891 does not contain any internal batteries The PM891 has two RJ45 Ethernet ports (CN1, CN2) and one RJ45 serial port (COM4) for connecting to the control network. The COM4 port is isolated and used for configuration tools. The PM891 supports CPU redundancy for higher availability (CPU, CEX bus, communication interface, and S800 I/O).
The Communication Expansion Bus (CEX-Bus) is installed on the unit. The CEX-Bus is used to expand the onboard communication port through the communication interface unit. Redundant communication interfaces can be used on the CEX bus. The CEX bus interconnect unit BC810 is used to improve the availability of the CEX bus by dividing the CEX bus into separate segments. The unit’s optical Modulebus can be used to connect up to seven clusters of S800 I/O units (each containing up to 12 units). Each PM891 is equipped with a unique Ethernet address that provides a hardware identity for the device.
Features and advantages
Reliable and simple troubleshooting program
Modular, allowing for gradual expansion
IP20 protection, no enclosure required
The controller has full EMC certification
High performance and large application memory use a pair of BC810’s segmented CEX buses with built-in redundant Ethernet communication ports
