14. COMMUNICATION FUNCTION
(4) Reading the setting
Read the parameter setting. Specify the parameter group in advance (refer to (1) in this section).
(a) Transmission
Transmit command [0][5] and the data No. corresponding to the parameter No., [0][1] to [F][F]. (Refer to
section 14.4.1.)
The data No. is expressed in hexadecimal. The decimal equivalent of the data No. value corresponds to
the parameter number.
(b) Reply
The slave station sends back the data and processing information of the parameter No. requested.
0
Data is transferred in hexadecimal.
Display type
0: Used unchanged in hexadecimal.
1: Must be converted into decimal.
Parameter write type
0: Valid after write
1: Valid when power is switched on again after writ
e
Decimal point position
[0]: No decimal point
[1]: Lower first digit
[2]: Lower second digit
[3]: Lower third digit
[4]: Lower fourth digit
[5]: Lower fifth digit
Read enable/disable
0: Read enable
1: Read disable
For example, data "1200270F" means 999.9 (decimal display format) and data "0003ABC" means
3ABC (hexadecimal display format).
When the display type is "0" (hexadecimal) and the decimal point position is other than 0, the display
type is a special hexadecimal display format and "F" of the data value is handled as a blank. Data
"01FFF053" means 053 (special hexadecimal display format).
"1 (Read disable)" is transferred to the "Read enable/disable" section and "000000" is transferred to the
data section when the parameter that was read is the one inaccessible for write/reference in the
parameter write disable setting of parameter No. PA19.
(5) Reading the setting range
Read the parameter setting range. Specify the parameter group in advance (refer to (1) in this section).
(a) Transmission
When reading the upper limit value, transmit command [0][6] and the data No. corresponding to the
parameter No., [0][0] to [F][F]. When reading the lower limit value, transmit command [0][7] and the data
No. corresponding to the parameter No., [0][0] to [F][F]. (Refer to section 14.4.1.)
The data No. is expressed in hexadecimal. The decimal equivalent of the data No. value corresponds to
the parameter number.
(b) Reply
The slave station sends back the data and processing information of the parameter No. requested.
