MODBUS Register Access
Gateway:
MODBUS Registers 1-199
See the MODBUS map overview for more information (see below).
Remote:
Each Remote is provided with a dedicated range of 50 (fifty) MODBUS registers as outlined
in the table below. Access to a remote is made by adding the MODBUS register you wish
to access to the base address of the remote in question.
For instance, the firmware revision is located at register 6 into each
remote‟s address
space. Therefore, reading the firmware revision requires a read from register:
Remote #1 would read from 206 (200 + 6).
Remote #6 would read from 456 (450 + 6).
Writing to a Remote operates the same way. For instance, Configuration Register 0
(CONFIG_0) is located at register 38. Writing to CONFIG_0 requires writing to:
Remote #1 would write to 238 (200 + 38).
Remote #6 would write to 488 (450 + 38).
