Note:
Constants configured in the beginning of receive formats are have different functions as shown below:
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

Receive Format
Receive status:
Receive completion output:

0
Start delimiter of incoming data does not match the receive format
RXD instruction keeps waiting for valid incoming data,
and completes data receiving after receiving valid data
including a correct start delimiter.

Receive status:
Receive completion output:
74
1
Constant for verification of incoming data does not match the receive format
Receive status stores 74 (= 64 + 10)
RXD instruction completes data receiving. To repeat
receiving incoming communication, turn on the input for
the RXD instruction.
