Configuration parameters of the “UART1” sub-menu of the “Networks” menu
The parameters are only visible if the application software is set up for the RS-485 (MODBUS MASTER/SLAVE, BACnet MS/TP) port to be configured to support the
MODBUS communication protocol.

timeout of the local MODBUS communication, that is of the device (when
the time set by this parameter from the sending of the request has
elapsed without receiving an answer, the sending of the request is con-
sidered to have failed and the next request is sent; this is important
only when the communication protocol is MODBUS master)
