A
Program example of nonprocedural protocol or bidirectional protocol
The following shows the program examples to connect an external device (personal computer) to the CH1 of C24, and to
send/receive data by using the nonprocedural protocol or bidirectional protocol with input/output signals.
■Module parameter setting of C24
1. Set the items in "Basic Settings" of "Module Parameter" as follows.
[Navigation window] [Parameter] [Module Information] [RJ71C24] [Module Parameter] [Basic Settings]
When communicating by using the bidirectional protocol, set "Bidirectional protocol" for the communication protocol setting.
2. Set the items in "refresh settings" of "Module Parameter" as follows.
[Navigation window] [Parameter] [Module Information] [RJ71C24] [Module Parameter] [Refresh setting]
3. Write the set parameters to the remote head module of the intelligent device station on CC-Link IE Field Network. Then,
reset the remote head module or power the system off and on.
[Online] [Write to PLC]
In this example, default values are used for parameters that are not shown above. For the parameters, refer to
the following.
