Example 2 Command Block–Example using a Network Address name
This example is the same as Example 1 except that the Network Address name of the remote host
(“PLC_1aa”) is used instead of its IP address. For more information on Network Address names,
see the chapter: “Network Administration Support”.
Establish a channel (Channel 7) to a remote host application server with a Network Address name
of “PLC_1aa”. Return the COMMREQ Status word to %R10. Send local PLC registers
%R50–%R57 to remote host. Repeat the send 10 times, once every 7 seconds, with a timeout of
500 ms for each transfer.

used here to identify the
client PLC—the PLC
that initiates the
communications
request.
The term SRTP Server
is used here to identify
the Host server.
