Communication Ports (Fbus, Bms2 Y Plan) - ECOFOREST ecoSMART e-manager Installerhandbuch

2.6. Communication ports (Fieldbus1, BMS2 y pLAN)
The e-manager has three entrances connected to the different communication ports of the controller on the bottom rail.
Communications with the controller are made using the Modbus RTU protocol under the RS485 standard.
Only use shielded three-wire cable. The use of any other cable may cause a malfunction of the installation.
NOTE
The Fieldbus1 port is used to read the electrical parameters and the power balance at the main electrical income. To do this, it is
necessary to wire the aerial connector of the FBus terminal block to the CEM-C20 energy meter of CIRCUTOR (included with your
e-manager) as shown below.
