■ Read setting data (Communication/Modbus)
This command is used to read setting data. The number of elements
can be set from H'0004 to 006A (4 to 106) to allow successive reading
of 2 to 53 items of setting data in contiguous addresses.
To specify the variable type or address, see "Appendix Setting list"
(P.A-6). The upper limit of an address will vary depending on the
variable type.
This command can be used in both setting area 0 and setting area 1.
When used in setting area 1, the response for the remote SP monitor,
ramp SP monitor, and valve opening monitor is "0" and the response
for the status is as indicated in the notes in "Appendix Setting list
Status" (P.A-8).
The above indicates a normal end. For information on error responses,
see "7.5 Reading the variable area" (P.7-10).
