DPRAM_CM5XX_SENDΒΆ
The Function Block DPRAM_CM5XX_SEND is used for sending data to the CM5xx. This data is provided in the configured memory area (DATA), i.e. the memory address for the data to be sent via ADR operator. The Function Block is activateded by a high signal at input EN. It remains active until the input EN is set to FALSE. The slot number and the channel of the CM5xx are put to the inputs SLOT and CH. At the input DATA_LEN the length of the data to be sent is specified in bytes. The successful data transmission is indicated by DONE=TRUE and ERR=FALSE. If during operation an error was detected, this is indicated at the outputs ERR and ERNO.
Note
Sending data with the function Function Block DPRAM_CM5XX_SEND is edge-triggered, i.e. that each sending process is triggered 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.
