Measuring Devices 7T5 8 time and puse counters Overview The counters are designed for instaation in switching, contro and distribution boards and can be snapped onto standard mounting rais 35 mm acc. to E 6075. Function Time counters count the time in hours with an accuracy of two decima paces (hundredths of hours). The puse counter adds the number of puses, e.g. the maing operations of devices. In the case of eectronic counters, the counting resut is saved indefinitey in the event of a power faiure (EEPROM). On recovery of the power, the counting is continued from the saved vaue.

Matrix seection Conventiona measuring instruments usuay provide votage, current or other simiar vaues for three phases. Mutimeters with their matrix seection are consideraby more fexibe and more universa. The 3-fod indications are seected using the rotary and the desired indications confirmed with O.

The A server can either be ined directy to a PC or in a company-specific A. A devices are switched in parae with a shieded 2-wire A interface ine. The hardware interface between the devices and the A server supports pug-and-pay technoogy. Function Operator interface The operator interface is aready we-nown and widey used for office communications. It enabes a operators to configure their own programs to suit individua requirements. The integrated macros are based on MS Visua Basic and are discosed. This enabes a software manufacturers to create their own company software or to integrate their devices in an existing software. The MS Exce operator interface supports: Seection of any device that is connected to a A server Definition of imit vaues (aarm tripping) for up to 0 measured vaues for each device Running diagnostics of a system Copying and separate storage of instantaneous measured vaues for documentation purposes. Measured vaues The measured vaues vary according to the measuring device specifications of the muticounters and E-counters. The foowing appies: A manuay read out measured vaues are transmitted from the A server and isted in MS Exce. Pug and pay Each device has a factory-set 2-digit software number. This number aows the A server to recognize the connected device and initiaize the appropriate data protoco. This software number is entered on the device and can be read in MS Exce. This enabes the identification of a device and its instaation ocation. imit vaue signa Microsoft Exce supports the setting of any imit vaues as minimum and maximum vaues. The deay specifies how ong a measured vaue shoud be pending before a signa indicates that it is exceeded. Data protoco The data communication between the A server and PC uses the TCP/IP protoco. This aso supports integration in PROFIET. Date and time The date and time of the PC is used. Transmission rate The data transmission rate is imited due to the A characteristic, e.g. the internet or the interna networ. The transmission rate of data between the A server and the connected devices is consideraby higher and does not reduce the overa resuts. Data storage Address data of the devices and the PC and the continuousy received measured vaues are stored in the A server for a minimum of 0 years. In the event of a power faiure, a warning is sent over the A. On power recovery, the A server automaticay restarts and the saved data are automaticay sent to the PC.
