Best practice guide for Enless receivers communication with your BMS
RX MODBUS
We recommend maintaining a delay of at least two seconds between two consecutive Modbus requests sent to the receiver. As a reminder, the minimum transmission interval for Enless transmitters is one minute, so there is no need to configure very high polling frequencies.
To optimize the polling process, we recommend reading consecutive Modbus points in blocks. This reduces the number of Modbus requests sent to the receiver.
When reading Modbus points in blocks, we recommend not exceeding 64 points at a time.
The Enless receiver acts as a server and can only accept one TCP client at a time. Requests from another Modbus device may disrupt communication with the connected TCP client.
RX BACNET
If you are not using COV, we recommend maintaining a delay of at least two seconds between two consecutive BACnet requests sent to the receiver. As a reminder, the minimum transmission interval for Enless transmitters is one minute, so there is no need to configure very high polling frequencies.
The number of COV (Change of Value) subscriptions must not exceed 80.
