*3 The "Set by" column indicates the following.
System: The CPU module stores the execution result of the SP.SOCRCV instruction.
*4 0 to 2046 for the QnUDE(H)CPU with a serial number (first five digits) of "12051" or earlier
● Receive data size is 2046 bytes by default. To receive data over 2046 bytes, change the receive data size with the
SP.SOCRMODE instruction.
● When the SP.SOCRCV instruction is executed, data are read from Socket communication receive data area at END
processing. Therefore, executing the SP.SOCRCV instruction will increase the scan time.
● If the CPU module receives odd-byte data, invalid data is stored to the high byte of the device where the last received
data is stored.
