Pragma Engineering has designed and developed in 2011 an Inverter DC Current Inputs Monitoring System for photovoltaic power plants.
The monitoring system is able to acquire DC input currents of inverter devices included in a photovoltaic plant. In detail the monitoring system includes 8 current channels in order to acquire 4 DC lines for the master unit inverter and 4 DC lines for the slave unit inverter.
The system has no views on local, but it can be queried via MODBUS TCP/IP protocol by Ethernet connection included in the controller module. The system has been configured with MODBUS parameters in order to permit requests by SCADA application supporting MODBUS communication protocol.
Any fails of the transducers or of the system will be storage in the status discrete registers, in addition a led will be blinking in case of transducer fail or will be on in case of system fail (in normal operating mode the led will be off ).(IEC 60068-2-6, IEC 60068-2-64)5 grms, 10 to 500 Hz

Starting from 1999 Pragma Engineering S.r.l. was charged by City of Siena to execute a monitoring intervention on tuff spreaded in Piazza del Campo when is running the Palio of Siena and this monitoring activity has the objective to improve safety conditions of jockeys and horses during the race.
The main intend of the monitoring is the characterization of the soil (tuff) spreaded on the square when the race is running through detecting microclimatic parameters and physical features of the soil.
