Section 6-8
Confirming the Communications between the NT31/NT31C and the Host
Execute the host program and confirm that the following operations are performed
normally.
S Confirm that the NT31/NT31C screens switch in accordance with the host pro-
gram.
If the screens do not switch correctly, check the connection between the host
and the NT31/NT31C, and also check if the hardware settings are correct. For
details, refer to Section 4 “Connecting to the Host from the RS-232C Port”, or
Section 5 “Connecting to the Host from the RS-422A/485 Port”.
S Confirm that the operation results of touch switch and numeric value/character
string input at the NT31/NT31C are sent to the host correctly by displaying the
contents of the host words and bits using a peripheral tool (e.g. SYSMAC sup-
port software).
If the results of operations at the NT31/NT31C are not sent to the host correctly,
check the setting of the display elements. For details on setting display ele-
ments, refer to Section 7 “NT31/NT31C Functions”.
