5.3 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.
