“Zelo Industrial Solutions d.o.o.” is a software company specializing in information systems in manufacturing. The company was founded by a team of experienced engineers who spent decades building up systems with different names: SCADA, Historian, Level 2 or MES, but with common features such as: control systems connectivity, process visibility, material tracking, production management. Our solutions are based on integration of various control systems (PLC, DCS, various measuring instruments…) by utilization of any available communication protocol (MODBUS, PROFIBUS, CANbus, BACnet, OPC...), and integration of information systems such as WMS, MES, LIMS, PPC or ERP, and in recent years we are also connecting our systems with cloud solutions, thus following popular Industry 4.0 trends. We like to describe our solutions as “tailor made MES” (Manufacturing Execution System), and unlike many other out-of-the-box solutions, we are aiming at providing best return on investment (ROI) by finding and applying most suitable ICT technologies for our customers’ business and manufacturing process.
