B.2.4 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 0x 00 0x00 0x00 0x00 0x00 0x00
I data 0x00 0x00 0x 00 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 Parameter value
O data 0x00 0x 02 0x C1 0x 91 Unused Unused Unused 0x 00
I data 0x00 0x 02 0x C1 0x 91 0x00 0x00 0x00 0x 00
Step 3 After receiving the input data with ResID 0xC send output
data with ReqID = 0x0 and wait for input data with ResID =
0x0:
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 0x02 0x 01 0x91 Unused Unused Unused 0x00
I data 0x00 0x02 0x 01 0x91 0x00 0x00 0x00 0x00
