摘要：Copper Institute, Industrial Informatics department, is developing and applying network real time process monitoring and control systems. The kernel of those systems is the microprocessor measuring station - MMS. In hardware and software point of view, MMS is a type of PLC (programmable logic controller) with some of local and remote functional possibilities. In monitoring and control of technological processes in many production plants, occurs a necessity for transfer of information and interaction with the process from remote distances (from control center, for example). It is obvious that for these requirements there should be available monitoring and control systems for operation in network environment. Special attention is paid to communication sub-systems, i.e. development of cost viable and in practice easily applied solution. Some of these systems are already in use. The paper presents hardware and software characteristics and performances, with special regard to network operation and possibilities.
