4 SETTINGS AND PROCEDURES PRIOR TO OPERATION
4.5.3 The Intelligent function module interrupt pointer setting
The following explains the interrupt pointer setting with GX Developer in order to
receive data using an interrupt program.
For the method to receive data using an interrupt program, see User's Manual
(Applications).
[Setting purpose]
The intelligent function module interrupt pointer sets the information to read the
receive data with an interrupt program of the programmable controller CPU
during communication using the non procedural/bidirectional protocol.
By performing this setting, an interrupt program starts when data is received from
an external communicating device and the reading of data received by the
programmable controller CPU becomes possible.
