1. General Introduction
The CPU board of the PM857K01controller contains the microprocessor and RAMS memory, a real-time clock, LED indicators, INIT push button, and a Compact Flash interface.
The base plate of the PM857K01 controller has two RJ45 Ethernet ports (CN1, CN2) for connection to the Control Network, and two RJ45 serial ports (COM3, COM4). One of the serial ports (COM3) is an RS-232C port with modem control signals, whereas the other port (COM4) is isolated and used for the connection of a configuration tool. The controller supports CPU redundancy for higher availability (CPU, CEX-Bus, communication interfaces and S800 I/O).
The high integrity functionality is enabled by the addition of a SM812 module and the SIL certified software. This enables non-critical control schemes to be upgraded to SIL certified schemes by the addition of a plug-in SM81x module, plus selection of the appropriate software. The AC 800M High-Integrity also offers IEC 61508 and TÜV-certified control environment for combining safety and business critical process control in one controller unit without sacrificing the safety integrity.
The PM857K01 can handle Max 128 I/O signals. Certified for SIL3. Requires configuration according to Safety Manual
