Overview
Essential details:PM858K01 3BSE082895R1 Processor Unit ABB
Products Description
The CPU board contains the microprocessor and RAM memory, a real-time clock, LED indicators, INIT push button, and a CompactFlash interface.
The base plate of the PM858 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).
Simple DIN rail attachment / detachment procedures, using the unique slide & lock mechanism. All base plates are provided with a unique Ethernet address which provides every CPU with a hardware identity. The address can be found on the Ethernet address label attached to the TP830 base plate.
(Only compatible with System 800xA 6.0.2, Compact Control Builder 6.0.0-1 and onwards. Please see Product Update for more information.)

Remote input devices enable users who are far away from the computer to perform batch input jobs on distant computers. The simplest structure of the device consists of a printer, a card reader and its communication-control processor. Since the information in the communication line is transmitted in serial mode, the communication control processor in the equipment needs to convert the information input to the computer from parallel to serial and send it to the communication line, and then output the information sent from the communication line from serial to parallel. In addition, information transmission and error correction should be monitored according to the specified communication procedures.
In order to realize the long control distance and high precision, the accuracy of remote equipment information must be improved. Because of the communication problems between multiple systems, sometimes the remote instruction information is typed manually. In the case of large data volume, the error rate of information typing increases. In order to improve the accuracy of input remote device information, an ARM-based automatic input conversion system for remote device information is developed. The remote device information is transmitted to the system through RS485 protocol. The system analyzes the information protocol and data, and forwards the obtained keyboard and mouse data to the control system through PS2 keyboard protocol and serial mouse protocol. In practice, the remote equipment information automatic input conversion system improves the accuracy of information input and the efficiency of control automation.
System working principle
The system receives keyboard and mouse commands in real time and forwards them to the computer host to realize normal keyboard and mouse information input. Under the control of the external device, the keyboard and mouse information transmission channel is switched automatically, and the instructions sent by the external device are received. The information that can be received by the computer host is generated and sent to the computer host according to the designed time sequence, so as to realize the simulation key person of various parameters in the remote device information. After parameter typing, the control will be returned to the keyboard and mouse in time to restore the normal control function.
