to
be changed to 100 Hz. The value must be recalled
after a mains failure, so it is written in EEPROM.
PKE = E0CA Hex - Write for parameter 202

Example - Selection of a data value:
You wish to select kg/hour [20] in parameter 416
Process units. The value must be recalled after a
mains failure, so it is written in EEPROM.
PKE = E19F Hex - Write for parameter

Example - Reading a parameter value:
The value in parameter 207 Ramp up time 1 is required.
The master sends the following request:
PKE = 10CF Hex - read parameter 207
Ramp up time 1
IND = 0000 Hex
PWE
HIGH
= 0000 Hex
PWE
LOW
= 0000 Hex
If the value in parameter 207 Ramp-up t ime 1 is 10
sec., the response from the slave to the master will be:
Conversion:
Under the section entitled Factory Settings the
various attributes of each parameter are displayed.
As a parameter value can only be transferred
as a whole number, a conversion factor must
be used to transfer decimals.
E
xample:
Parameter 201 Output frequency, low limit f
MIN
has
a conversion factor of 0.1. If you wish to preset the
minimum frequency to 10 Hz, the value 100 must
be transferred, as a conversion factor of 0.1 means
that the value transferred is multiplied by 0.1. The
value 100 will thus be perceived as 10.0.
