#01E1 Control data: Communications port No. 0, serial port No. 1, and inner board are used.
#0258 Control data: Send-receive sequence No. 600 (with ASCII code conversion and response) is set.
D00000 First word No. of send data: DM00000 is set.
D00500 First word No. of received data storage: DM00500 is set.

DM address Data
D00004 8000
D00005 0000
D00006 0002
MRC, SRC: Memory Area Read is used, so MRC = 01 Hex and SRC = 01 Hex are set.
(Hexadecimal settings are converted into ASCII code during communications.)
No. of send data bytes: If send data from D00004 to D00006 (6 bytes) are converted into
ASCII code, it will become 12 bytes. So, 000C Hex is set.
Data part of FINS-mini command text (PDU): Data is set in Hex. The settings will be
converted into ASCII code during communications.
No. of send data words: There are seven words from D00000 to D00006, so 0007 Hex is set.
Node No.: The node number of Cam Positioner is 00, so 000 Hex is set.
Same as above.

Memory area code: The memory area code for Resolver speed and present cam angle is “80.”
Beginning address: The address for Resolver speed is “0000.”
No. of items: There are two items (Resolver speed and present cam angle), so “0002” is set.

DM address Data
Received data: The present cam angle (359 in this example) is stored
after being converted from ASCII code into a hexadecimal value.
Received data: The cam speed (800 r/min in this example) is stored after
being converted from ASCII code into a hexadecimal value.
No. of received data words: There are four words from D00500 to D00503, so 0004
Hex is stored.
Response code: MRES = 00 and SRES = 00 are stored at normal completion.
