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