Three Phase and Three Phase CT Type PMSFL User Manual - 22
Question #3
Can the PMS monitor the AC without the neutral?
Answer
No, can not
Question #4
Can I connect the Modbus output directly to alternative BMS interface?
Answer
We use the Modbus RTU standard on RS485. If the BMS supports the Modbus RTU standard on
RS485, it can support that BMS.
Question #5
Is it possible to connect multiple Modbus devices on the securityProbe’s RS-485 port
simultaneously?
Answer
Yes, we can use many Modbus devices on our RS485 port in the same time. However, the Modbus
device should be a Master or Slave device, so we cannot use the SEC in both modes simultaneously.
We need to choose our securityProbe to one mode. The page "Settings - Connectivity - Modbus" is
where this setting is found for enabling our securityProbe to be the Slave device.
Question #6
Do you have an example of how I would connect the PMS to monitor the voltages from my PDU or
power distribution unit?
Answer
Yes, please see the diagram following page that shows how these can be connected.
