Abstract Target of this contribution is description and implementation production control system to production plant. Currently is production control system very popular in serial production mainly in automotive industry. This tool is very helpful for monitoring production it means „getting“ data from production processes, making analyzes, monitoring actual situation on the line (machine), tracking actual technical conditions of production machines or tracking quality of materials which are output from machines. Production control system is tool which has been developed for saving money and reduce costs of production. For using of this tool we can say where is in production „bottleneck“ and where we have weaknesses. Production control system is very good tool for planning of production as well. Planning is very important for effectivity of production. Currently in production plant is profitable not to have any stock mainly in case of production „just in time“, where we have to receive data as soon as possible because we need to react for changes which have been happened on the line.

Introduction Production control system is an interface that helps to make production more efficient by using input data, which are obtained from various devices and processes. At present, all devices in light or heavy industry are connected to network, for example profinet. This network transmits information (packets) to a server where stores this information in a database. All communication with the machine is currently stored on the global disk. Today, most machines have a separate control unit, usually a PLC (programmable control machine intended for industry), or a computer. These control systems recieve signal from the individual sensors, which are connected in the machines, according to these signals which have been recieved from the machine changes production the desired product. According to the sensors, the control units are able to register the times of individual subprocesses (process sequences), various values of physical quantities, etc., which serve to regulate or adapt the process as required. However, it is not excluded that these values can be permanently stored in database systems (see Figure 1). Similarly, if a sequence is tracked in the process, they can be registered where
