Client Id; Mb Type - Honeywell FMC2000 User Manual

FMC2000 User's Guide
Note: Always compare baud rates at the sending and receiving
ends. If they are the same but data is dropped, try a lower setting.
Check with your IT department for further guidance on setting
baud rates.
To set the Baud Rate:
1. Press Enter
2. Use the Up and Down arrows to select a baud rate.
3. Press Enter.

18.3.2 Client ID

When setting up RS-485 connections according to the Modbus
protocol, a unique Client ID is necessary.

1. Press Enter
2. Input a number from 1 to 246.
3. Press Enter.

18.3.3 MB Type

MB Type is short for "Modbus Type." There are two variants for
Modbus serial connections, RTU and ASCII. Each represents
numerical data using slightly different protocol details. Modbus RTU
is a compact, binary representation of the data. Modbus ASCII is
human readable, and more verbose. The RTU format follows the
commands/data with a cyclic redundancy check (CRC) checksum,
while the ASCII format uses a longitudinal redundancy check
checksum. Important: Nodes configured for the RTU variant do not
communicate with nodes set for ASCII, and vice versa.
1. Use the up and down arrows to select either RTU or ASCII.
2. Press Enter.
Note: For detailed technical reference material covering the FMC2000's
ModBus implementation, see Appendix G, beginning on page 101.
