Quartzo is a medium-sized PLC that was developed thinking in industrial automation machines or small sectors of industry. Quartz can be expanded using serial or Ethernet communication. It has two serial connections in ModbusRTU protocol that can be configurated either as a slave or master, completely independent of each other. The communication rate can range from 9600 bps to 115200 bps. In Ethernet port it has the client / server platform in Modbus / TCP also independent of each other. As a server, Quartzo can connect up to 8 clients simultaneously and as a client can connect to up to 32 servers in Modbus / TCP. To achieve high performance with all this communication capability, Quartzo has a high performance DSP processor running at 500MHz. In addition to this high performance you can use up to 16 KB of variables in Ladder or store up to 8K instruction (32 KB STL instructions).
