Technical Specification:

Application Examples:
  1. PLC remote diagnosis and remote on-line programming
    Any PLC cabinet is delivered with pre-installed GSM modem (without SIM card) connected to the PLC on-line interface. In case of trouble the maintenance slides in any SIM card at hand and the PLC supplier can dial-up the GSM modem and go on-line from anywhere in the world. Any industrial on-line protocol will work up to a baudrate of 9.6 kBaud.

  2. PLC Data Communication Network
    Two PLC's can connect poit-to-point with any industrial, serial protocol (Modbus e.g.) and exchange data on demand or scheduled

  3. Telemetering
    Any RTU, data logger etc. at a remote location creates historical data files. A SCADA server (or data base server) in central location polls these files according to schedule (one time a day e.g.), updates the historical data base seamlessly and creates reports.
    Remote alarm conditions trigger automatic reporting as SMS message to mobile phones of stand-by personal, SMS messages or data link to the central computer.

  4. Pipeline Monitoring
    A flow computer is polled periodically from a central computer (SCADA or SQL server)
    Remote alarm conditions release the flow computer fault relay connected to a digital input of the GSM modem and trigger a dial-up sequence to the pre-stored central computer phone number. The central computer will then initiate the serial data link and read the alarm condition. Or the trigger sends a pre-stored SMS alarm message containing the fault location to a maintenance mobile phone.
     
  5. Supervisory Control On-Demand
    A remote PLC is part of a process (remote pump e.g.) but no permanent data communication is available, but still the system can react fast (less than one minute delay) and seamless historical data are available.
    The remote PLC creates historical data files (like a data logger) and the central SCADA server polls the files every day and updates it's historical data base. Remote alarm conditions or central control commands establish a data communication on demand.

  6. Home Security
    A micro PLC, not able to send dial-up sequences or SMS text, can still select one out of 20 different SMS alarm messages and one out of 40 dial-up numbers. All of them are pre-stored in the GSM modem and the micro PLC selects with slow pulses created from a digital output. This procedure can send SMS alarms to mobile phones or supervision computers. In return digital GSM modem outputs can switch devices remotely triggered from an SMS message. As option remote switching can be password protected.

  7. Other Applications: Remote Meter Reading, Truck fleet Supervision, Payphones etc.
