This Function Block is used to send data to the PM5xx CPU.

The data to be sent are provided in the configured memory area, i.e. at the memory address specified at input DATA via the ADR operator.

The Function Block is enabled by a TRUE signal at input EN. It remains active until input EN is set to FALSE. The channel of the PM5xx is specified at input CH. The data length (in bytes) to be sent is specified at input DATA_LEN.

Successful data transfer is indicated by DONE = TRUE and ERR = FALSE. The outputs ERR and ERNO indicate whether an error occurred during Function Block processing.

Note

Sending data using the DPRAM_PM5XX_SEND Function Block is edge-triggered, i.e. each sending process is initiated by a FALSE/TRUE edge at input EN.

Note

DPRAM message-based data exchange allows a maximum of 260 Bytes per message to be sent or received.
