This Function Block is used to receive data from a PM5xx CPU.

The data received are stored 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.

Output DATA_LEN displays the length of the received data in bytes. Successful data reception is indicated by DONE = TRUE and ERR = FALSE. The outputs ERR and ERNO indicate whether an error occurred during Function Block processing.

Note

Data reception using the DPRAM_PM5XX_REC Function Block is not edge-triggered. Therefore, input EN must be TRUE during data reception.

Note

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