Global Port Number (FFH)
Active for connection mode (1 : n).
When the port number is set as [FFH] and a command is executed, all V series units that are
connected send a response in reply to a command from the host.
Commands for which global port number are active are shown below. If commands other than these
are used, a command error will occur.
Responses to global port numbers are not transmitted to the host. However, responses are written in
write area (n + 8) as shown below.
