1-9-11 SRM1 NT Link Communications
Using the NT link, the SRM1 PC can be connected to the Programmable Ter-
minal (NT Link Interface.) The RS-232C port can be used to the NT Link.
NT Link is possible only with the SRM1-C02-V1, which has an RS-232C port.
PC Setup Settings The settings relating to NT link PC communications must be set as shown in
the following table.
Note 1. If an improper setting is used, a non-fatal error will occur, AR 1302 will be
turned ON, and the default setting (0 or 00) will be used.
2. For information on the NT link settings for another OMRON PC, refer to that
PC’s Operation Manual.
3. If an out-of-range value is set, the following communications conditions will
result. In that case, reset the value so that it is within the permissible range.
