Software Features of Communication Protocol : 

The Panel board acts as a Slave, meaning that it stays on standby awaiting commands coming in from the BMS. 

Note: 

Use of the MODBUS/JBUS RTU 

excludes

 the “connection with UPS network” function in which a Master Panel 

queries panels of Slave units and permits communication with a Local/Remote PC; in the MODBUS/JBUS RTU 
protocol none of the panels is given Master status and none of the UPS panels  may communicate with the 
Local/Remote PC.
