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

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

Step 3

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