Measurement and control system built on a series of modules I - 7000 allows acquisition of measurement signals and control, both in individual buildings as well as in complex automation systems. We offer over 70 different modules including: digital inputs / outputs, inputs / outputs, A / D and D / A, strain gauge and thermocouple inputs, clocks, timers, converters, RS-232 to RS-485 repeaters RS-485 Converters RS-232/422/485 to USB, MMI interfaces, applications software. These modules are connected together with two RS-485 cables form a network. The same network can be connected to 256 series modules I-7000. In addition, our products are compatible with solutions from other manufacturers which allows their use in existing automation systems without incurring large expenses.

Programmable Input / Output

The scope and mode of operation (input or output) modules are fully customizable. The user configures the modules remotely commands from the host. This allows the use of modules for different applications. This increases the application flexibility and reduce the cost of the system.

Dual Watchdog

Module I-7000 series are controlled by two watchdog-s: the module and host.Watchdog in a built-in module is a hardware-head. It is designed to perform automatically reset the microprocessor when the module is working correctly. The new software-watchdog monitors the system unit (eg a host PLC or PC) and when an incorrect operation of this unit can drive the output module to a safe state (selected at time of failure of the host).

Working without maintenance

I-7000 systems can work under the supervision of the SCADA system, or you can use the PLC to directly control the system I-7000.

Simple installation and connection

Modules can be mounted I-7000 series of DIN rail, wall or "myself" by a special handle "Piggy Back". Each module is equipped with a special terminal allows quick and safe connection of signal cables and power cords.

The communication protocol

All I-7000 modules using a simple communication protocol: query-response. Each module sends the data when you query the, otherwise it will not send data.Together the modules provide a complete specification of the protocol which enables easy and fast transport connections 7000-series modules with any application. Some well-known applications that can control the I-7000 modules directly. These PC industriali are the Labview, HP VIEW, Testpoint, ISaGRAF, etc. SCADA programs to communicate with the I-7000 can use the modules supplied with the OPC server.
