4) Hold Register Address Summary
Relevant Modbus functional codes: 0x03 (read multiple registers), x06 (write to multiple registers), 0x10
(write to multiple registers), 0x17 (read/write to multiple registers).
Application parameter address
The application parameter access address can be obtained from the parameter’s identifier when
ascertaining the access address, the method is to ignore the sub-class code in the identifier (following
referred to as “*”); let's see an example, for parameter identifier: HH.*.DD (e.g.F2.0.33), it will obtain HHDD
directly (hexadecimal format), and the access address for F2.0.33 is: 0xF233H. Below attached is the table
for respective conversion of access addresses:
dE.#.00 ~ dE.#.55 (read-only)
Status parameter address (read-only): The address conversion method for status parameter is similar to
that for application parameter. However, there is no ROM access address.
