Example of parameterising via FPC
A record in the position set table can be parameterised via
FPC in the following manner:
Step 1
Output status of the 8 bytes of FPC data:
Byte 1
Byte 2
Byte 3
Byte 4
Byte 5
Byte 6
Byte 7
Byte 8
Reserved Subindex ReqID/ResID + PNU
Parameter value
O data

0x00
0x00
0x00
0x00
0x00
Step 2
write record number 1 with absolute positioning:
PNU 401, subindex 2 ć Modify parameter value, array, byte:
ReqID 12 (0xC) with value 0x00
Byte 1
Byte 2
Byte 3
Byte 4
Byte 5
Byte 6
Byte 7
Byte 8
Reserved Subindex ReqID/ResID + PNU

Step 3
After receiving the input data with ResID 0xC send output
data with ReqID = 0x0 and wait for input data with ResID =
0x0:
