There are two unit address (DA2 in FINS header) used in CP1L-EL/EM series
PLC units.
0xFA It is used for the two new added FINS commands relative with built-in
Ethernet Port. (Ethernet controller reset command and Ethernet Port
information read command)
0x00 It is used for the FINS commands other than the two commands above.
Ethernet controller reset command and Ethernet Port information read com-
mand can only be executed by other PLCs or computers on the Ethernet net-
work. It cannot be executed by CMND(490) instruction in the user program.
Response codes are 2-byte codes which indicate the results of command
execution. They are returned in the response following the command code.
The first byte of a response code is the MRES (main response code), which
categorizes the results of command execution. The second byte is the SRES
(sub-response code) which specifies the results.
