⚠️Recommendations

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.
