User Communication Receive Instruction Dialog Box in WindLDR
Selections and Devices in Receive Instruction Dialog Box
Receive Format
Receive format, designated by source device S1, specifies data registers to store received data, data digits for storing data, data
conversion type, and repeat cycles. A start delimiter and an end delimiter can be included in the receive format to discriminate
valid incoming communication. When some characters in the received data are not needed, “skip” can be used to ignore a
specified number of characters. BCC code can also be appended to the receive format to verify the received data. One RXD
instruction can receive 200 bytes of data at the maximum.
S1 (Source 1)
Note:
Total byte count of the receive format is shown in S1 of RXD instruction on the ladder diagram of WindLDR.
