Design and Integration Features
The Siemens E89700-B9104-A1 functions as a PROFIBUS DP slave within the SIMATIC S7 environment . The module maps LON device data objects directly into the I/O area of the S7 PLC. It operates as a polling device that cyclically queries connected LON devices and transmits data changes to the PROFIBUS master. The module does not require LON network variable bindings, which simplifies engineering and commissioning. The SICLIMAT Engineering Manager stores common DESIGO RX applications as “Typicals” for automated engineering.
System Compatibility and Use Cases
The Siemens E89700-B9104-A1 integrates with SICLIMAT X building management systems version 3.1 or higher. It supports individual room control applications, variable air volume systems, and heating/cooling control loops . Facilities managers use this module in office buildings, hospitals, and educational institutions. The module supports the connection of up to 63 bus users per LON segment for comprehensive building automation.
