Long-term memory
The long term big module memory gives the user the ability to select up to three different mean
demand measurement values synchronously. This is integrated with the RTC into 5, 10 or 15
minutes time for a week interminably. The stored data can at the arbitrary time be downloaded from
the PM-30E to the PC and then can be distributed on spread sheets and the curves can be plotted.
For example the user can get the load profile [kW] of a consumer/plant in week view or he can
analyze the data over a chosen interval of time..

Communication Network Port
The PM-30E is equipped with PC bus (RS422/RS485) serial interface with one default. PC bus
interface knows about these up to the 250 PM-30E equipment in a bus network being connected to
a Network / connected each other. The communication becomes with the software program
PM-30NET steered by a PC. Two different ways of communication are at the user's disposal:
The bus network (Max. 1000 m of length get this) directly about an interface converter Obliged to
PC (external serial RS232 interface).
The bus network (Max. 1000 m of length become) directly about an interface converter with one
obliged to an external modem. The communication (between the PC and PM-30E) becomes about
this one Telephone lines built up. The user of a remote place can the plants so supervising the
software program PM30Net and evaluating. A PM-30E device must when here. Master being
