The following is a list of Modbus Registers that are remotely available.
Notes:
• There is a limitation on the maximum Modbus block size of 40 for integers and 20
for floats.
• Additional settings include:
– Baud: Set by parameter bU, 9600 baud by default.
– Parity: None
– Data bits: 8
– Stop bits: 1
– Flow control: None
• It is common for external software to apply an address offset of "1", so you may need
to add "1" to the Modbus addresses based on the software in the remote system.
• In newer versions of Modbus, you may have to append a "4" or a "40" prefix on the
registers listed.
For example, to get to "MACHINE STATE" in register 4002, you may have to access
register 4002, 4003, 44002, 44003, 404002, or 404003. Once you test your system and
get a valid response, you will know the rules to consistently apply to your system for all
addresses.
