BMS (Building management system) bus system
The desired bus system is selected in the upper part of the menu. All necessary parameters for the
respective communication type appear in the lower part of the menu.
Modbus RTU
The baud rate, parity and stop bit settings must be made in accordance with the values of the
“Master”. The following communication settings can be edited:
Baudrate:
1200, 2400, 4800, 9600, 19200 baud
Parity:
no
no parity
Even
even parity
Odd
odd parity
If the parity check (Even or Odd) is activated, either by selecting even or odd
parity, the amount of all the first characters transmitted in the data content is
counted. The parity is then set as “0” or “1” in order to generate an even or odd
result at 1.
Slave number:
Enter the desired slave device address that is to be addressed by the master (1
to 247). Address 0 is reserved for broadcast mode.
Date length:
Length of the data bits to be transmitted. Contains the information to be
transmitted. This field is subdivided into registers, the number of registers to be
transmitted and, if applicable, into information that is read out or stored.
Stopbits:
1 stop bit if parity is used; 1 or 2 bits if no parity is used.
