The ReceiveConfig instruction (receive configuration, Receive_Config) allows you to change receive parameters in runtime using your program. This instruction configures the conditions that mark the start and the end of received data. Any data pending in a CM is deleted when ReceiveConfig is executed.
Configuration changes of ReceiveConfig are saved non-retentive on the CM. The parameters saved in the device configuration are restored once the voltage returns to the CPU or the communication module. The ReceiveConfig instruction therefore must be called again from the user program when the voltage returns to the CPU or to the communication module in order to overwrite the parameters stored in the device configuration.
