(5) Reading the setting range
The following shows how to read the parameter setting range. Specify a parameter group in advance.
(Refer to (1) of this section.)
(a) Transmission
When reading an upper limit value, transmit the command [1] [6] and the data No. [0] [1] to [F] [F]
corresponding to the parameter No. When reading a lower limit value, transmit the command [1] [7]
and the data No. [0] [1] to [F] [F] corresponding to the parameter No. (Refer of section 4.4.1.)
The data No. is expressed in hexadecimal. The decimal equivalent of the data No. value
corresponds to the parameter No.
(b) Return
The slave station returns the data and processing information of the parameter No. requested.
For example, data "FFFFFFEC" means "-20".
Data is transferred in hexadecimal.
