Guide to good practices regarding the communication of Enless receivers with BMS

RX MODBUS

  • We recommend maintaining a delay of at least two seconds between two consecutive sendings of Modbus requests to the receiver. As a reminder, the minimum periodicity with which Enless transmitters can be configured is one minute. It is therefore not necessary to configure very high polling frequencies.

  • In order to optimize the polling process, we recommend that you read consecutive Modbus points in bulk. This helps reduce the number of Modbus requests sent to the receiver.

  • When reading Modbus points in bulk, we recommend that you do not exceed 64 points at a time.

  • The Enless receiver behaves like a server and can only accept one TCP client at a time. Being requested by another Modbus device can disrupt Modbus 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 sending of BACnet requests to the receiver. As a reminder, the minimum periodicity with which Enless transmitters can be configured is one minute. It is therefore not necessary to configure very high polling frequencies.

  • The number of COV (Change of Value) subscriptions must not exceed 80.
