ZFA-GSM-2
case study
Application description
ZFA-2 is copact system by the company SAE Elektronik GmbH for data acquisition from impulse counter or equipments with serial communication interface. It is used for data aquisition from electrometers and flow transducers for different types of volume, for example water, gas...
One of abilities to data transfer from submasterstations of ZFA-2 system is GSM network. Module ZFA-GSM-2 was developed for this purpose.
The module enables transparent data transfer through GSM network between control system and metering device connected to module ZFA-GSM-2 through RS-232, TTY or RS485. Communication rate on interface ZFA-GSM-2/control system could be different from communication rate between ZFA-GSM-2 and metering module.
The module contains two interfaces. One of them is used for parametrization of the module and onether one for connecting metering device.
SAE - Automation developped for the module ZFA-GSM-2 firmware and parametrization software for Windows 9x/NT/2000. Parametrization software enables set-up parameters of used GSM netwrork, parameter od serial interface to metering device, passwords for different levels of used and also PIN code for GSM-modem. By module switch to service mode it provides monitor of logging to the network and monitor the process states of the module.
Defined parameters is possible to store in the file and used again for more ZFA-GSM-2 modules.
