4.1.2.2 03 READ HOLDING REGISTER
This function allows the user to read the values of all the Parameters, Connections, Internal Sizes
and some status variables. Writing the correct address you can access these data (see the table
under for the address) ; considering the internal representation you can rightly interpret the read data
: as usual it is necessary to see the related tables in the specific description of the core :
starting address (hex)
0000
00C8
012C
0380
0200
0202
0203
0300
0320
0340
052C
084C
0C00
0D00
09DC
It is not possible to read more than 127 registers at a time due to the memory limits of the buffer.
The order number of the parameters, of the connections and of the internal sizes is the one related to
the lists contained in the description of the control's core.
See the specific documentation for data area application.
The status variable is the same for all the implementations; hereinafter you can find the meaning of
the most important bit :
15
Drive status
1 = Power soft
start on
referring to alarms and their enabling, the order number for the bit of the word corresponds to the
number of the alarm itself. (e.g. A2= external enable corresponding to the bit 2 of drive alarms )
