Holding Registers
Refer to Table 5–1 for table register definitions. When reviewing the table, it is
important to remember:
•
The register addresses referred to in Table 5–1 show the first address
of multiple addresses available per register (see “Size” column for
number of addresses per register). Do not add or subtract “1” from
the first address register number as this could cause conflict with
other register assignments.
•
The analyzer does not check for correct ranges. The host must ensure
that valid numbers are used. Any wrong value may lead to
unexpected performance.
If there is a Service Software connected (via USB), the Modbus
write command 16 (“Write multiple registers”) will always return
error code 6.
