Modbus RTU Communication (RS485)
Modbus RTU protocol communication is available as standard.
Its implementation must meet the following requirements:
-
A maximum of 47 registers can be read in a single message.
-
The Master controller must wait a minimum of 3.5 characters (4ms at 9600 baud) between 2 messages.
-
If there are multiple slave controllers on the same line of communication, the master controller must wait a minimum of
14 characters (16ms at 9600 baud) between the regulator's last response and the next regulator's first question.
-
Limit to 10 fast communications every 30 seconds.
-
Other communications have a response time of approximately 1s.

The maximum communication speed depends on the length of the cable and its quality.
The list of read/write accessible variables is available in the chapter XXIV DATA EXCHANGE TABLES.

Bacnet MS-TP Communication (RS485)
Bacnet MS-TP protocol communication is available as standard.
The MS-TP Bacnet cannot be functional if the IP Bacnet is enabled. If the IP Bacnet is enabled while the MS-TP Bacnet is also enabled,
the MS-TP Bacnet will be automatically disabled, priority is given to the IP Bacnet
.

XIV.11.
Modbus TCP Communication
The Modbus TCP protocol is enabled by default. It is automatically disabled when the IP Bacnet is enabled, and vice versa. So there
is always at least one of these 2 active protocols.
In Modbus TCP, the port number is always 502 (not adjustable) and the device ID is 1 by default.
DHCP is enabled by default.
