The MPD detector is one of two at NICA collider. For MPD detector control system the TANGO software was proposed. Time projection chamber (TPC) is the tracker of MPD. The TPC LV and HV systems concept is presented. It is based on CAEN equipment and OPC UA (OLE for Process Control) server protocol. The status of interface design for CAEN equipment based on OPC UA, TANGO server and GRAFANA is presented. GRAFANA will be used to present graphs of the variation in the parameters of HV and LV during the monitoring.
