INDUSTRIAL COMMUNICATION

INDUSTRIAL COMMUNICATION appropriate software interface which is provided. The communication with the control takes place using TCP/IP. OPC UA Security includes authentication and authorization, encryption, and data integrity by signing. Therefore the main control will be protected from any possible uncontrolled access. The 3 encryption levels are ‘No encryption’ level, Basic128Rsa15 and Basic256. Basic128Rsa15 is 128 bit encryption and Basic256 is a 256 bit encryption level. Exchange of certificates is another important security level. A communication is only possible, if both server and client have a valid certificates. The IBH Link UA supports certificates with levels: ‘Sign’ which contain signed certificates, Level ‘Sign and Encrypt’ contains signed and encrypted certificates and ‘Sign + Sign and Encrypt’ which may hold ‘signed’ or ‘signed and encrypted’ certificates as well. OPC Client One of the advantages of the IBH Link UA is that it supports client and server functions simultaneously. This allows data exchange between different OPC UA servers. For example control systems and other previous page equipment with OPC UA servers from different manufacturers can exchange data with each other. The configuration of the client functions will be made using a standard web browser. The controller can easily monitor data connections via the time stamp and variable status using the client function. The OPC UA Server automatically monitors the variable to be read and writes it into the PLC controller. If there is a fault, this is indicated in the variable status. Additional advantages An important advantage of this compact device is that it is an independent assembly and does not require a Windows PC.
