Note
1. The current status of the FTP server can be obtained from the service status
in the words allocated to the Ethernet Unit in the CPU Bus Unit Area in the
CIO Area. The first word allocated to the Ethernet Unit is n and is computed
as follows:
n = 1500 + (25 x unit number)
FTP Status Flag
0: FTP Server free
1: FTP Server busy
2. The FTP server can handle only one command at a time.
3. Do not simultaneously write a file with the same name to the same file device
in a CPU Unit from more than one Ethernet Unit or ladder diagram program.
Exclusive control is not performed.
