ProData® data logger

Applications

The ProData® data logger is suitable for collecting data and recording meter values, operating conditions and process data. The data can be used for analysing energy consumption, operating hours or for monitoring switch conditions and faults in buildings and companies etc. The alarm for faults or limit value violations takes place through the relay outputs, the analogue modem or field bus.

Data recording

The analogue measurement values can be recorded in set time intervals (1 sec ...12h) as minimum, average and maximum values. In the set time intervals (1 sec ...12h), the difference between the overall meter readings and the meter reading at the last recording time is shown. Condition changes to the inputs can be provided with a time stamp (1 sec resolution) and collected. Various internal events (e.g. failure and return of the electricity supply) are registered. Condition changes to the programmable limit values/alarm triggers can be recorded as an event with a time stamp. All recorded values and events are recorded in a ring buffer. This consists of 430KB and is sufficient for 3 months if the digital counters are recorded every 15 minutes.

Modbus master

The RS485 interface can be switched in the master mode. In this mode, the ProData® registers from other Modbus units can be read (e.g. additional ProData® or UMG 503). The ProData® can also write the results of the programmable comparators in the registers of other units. 

For example, this means that the number of relay outputs can be increased by connecting a corresponding module to the Modbus as a slave. In the Modbus-master mode, Modbus telegrams which enter the RS232 interfaces and are not intended for the ProData® are transferred to the connected slaves on the RS485 bus.
