5.3.9 Connection limit
Defines how many clients can access the server simultaneously.
5.3.10 Unit Identifier number
The Modbus 'slave address' field usually used on Modbus Serial Line is replaced by a single byte
'Unit Identifier'.
When the TCP is used as the communications protocol, the AC drive is addressed by its IP address
and broadcast messages are not possible. In this case, the unit identifier is useless. In the UDP, it is
possible to send broadcast messages and therefore the unit identifier becomes important.
To keep things simple, the unit identifier is checked when using both TCP and UDP. In TCP you can
use value 255 (non-significant) as a unit identifier and send the messages to all slaves with that
value.
5.3.11 Communication timeout
For Modbus, this value defines the time in which a message must be received (from Client in
Modbus TCP/UDP) before a fieldbus fault is generated. If timeout is set to zero, no fault is created.
