3.6.2 Building Management Systems
The Networked Wallmount WattStation will communicate to building management systems (BMS)
via Modbus over the CAT5 connection or WiFi. The EVSE comes with a Modbus register map that
the BMS integrator can integrate into their SCADA or server system(s).
Note: Static IP addressing should be used for the WattStation(s) and all Modbus clients.
3.6.3 Firmware Updates
The firmware for the EVSE will be upgradeable over the EVSE's TCP/IP interface (CAT5 or wirelessly
through the cellular router or WiFi Access Point). The firmware updates will allow GE to supply
customers with updated firmware that adds additional features to flexible charging algorithms,
ground fault detection performance, pricing models, communication protocols and other
performance enhancements. All firmware updates will be accessed and controlled through the GE
WattStation Connect.
