Chapter 7 Communication function
Remark
[Note 1] For application of GMWIN after remote connection, On-line menu can be used as in local connection. Functions for
program download/upload/monitor are available.
[Note 2] PLC control via modem depends much on modem performance and phone line status. If phone line is in deficient
status, connection may be released. In this case, try re-connection not immediately but in approx. 30 seconds starting
from (1).
H) To release connection in remote connection status, select Disconnect in On-line menu to display Disconnect
menu box as in the figure below indicating Disconnected.
I) If connection is released normally, Cnet I/F module and GMWIN are changed to initial mode to allow re-
connection when tried again starting from clause No.(1).
G) In addition to dedicated modem, optical modem and wireless modem also can be used equally for remote
connection, though communication medium between modems differs from each other.
[Figure 7.26] shows an example of remote connection via wireless modem. Connection method is same as in the
remote connection via communication between Cnet I/F module. When wireless modem is applied, remote
connection in 1 : N system where several remote Cnet I/F module stations are in existence is also available.
