7 SETTINGS FOR THE C24
7.6 Intelligent Function Module Interrupt Pointer Setting
The following explains the interrupt pointer setting with GX Works2 to receive data
using an interrupt program.
For the method for receiving data using an interrupt program, refer to the User's
Manual (Application).
[Setting purpose]
The interrupt pointer sets the information to read the receive data with an
interrupt program of the CPU module during communication using the
nonprocedural/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 CPU
module becomes possible.
