Note: Constants configured in the beginning of receive formats have different functions as shown below:
More than five constants are configured in the beginning of the receive format

Other than constants (data register, skip, or BCC) are included in the first five bytes of the receive format

Start Delimiter
Consecutive first 5 bytes only
Skip
When "skip" is designated in the receive format, a specified quantity of digits in the incoming data are skipped and not stored to
data registers. A maximum of 99 digits (bytes) of characters can be skipped continuously.
Example: When a RXD instruction with skip for 2 digits starting at the third byte is executed

RXD instruction completes data receiving. To repeat
1
receiving incoming communication, turn on the input for
the RXD instruction.
