iSAtech Cable Gateway Networking the BMS Control Units via cable
The iSAtech Cable Gateway can network iSAtech BMS Control Units and RS/EIA-485 Modbus RTU meters/sensors. The cable gateway transmits the delivery data and credit information from the iSAtech BMS Control Units and receives meter data from the Modbus meters. The cable gateway stores and transmits the data to the iSAtech PayU-Cloud via Ethernet. This enables online monitoring and billing as well as the transfer of credit balances and control information to all connected iSAtech BMS Control Units. Thanks to the integrated data memory, temporary operation without an Internet connection is also possible.
Communication with the iSAtech BMS Control Units occurs via the robust RS/EIA-485 bus. Additional sensors, electricity, water, and heat meters can be connected via the Modbus RTU protocol.

Synchronization

All data is stored locally to ensure operation, even during communication interruptions. Data is transferred via online synchronization. The synchronization interval can be configured as required.

Flexibility

The iSAtech Cable Gateway connects iSAtech BMS Control Units via the RS/EIA-485 bus and any Modbus RTU sensors. Thanks to their interoperability, the iSAtech BMS Control Units can be operated on the bus parallel to the sensors communicating via Modbus RTU with the appropriate communication security via encryption for critical telecontrol systems. The Modbus sensors are addressed conveniently and centrally in the iSAtech PayU-Manager.
