9.2 Transmission/Reception Processing Using User Frame
Register Data
The following explains how the Q series C24 transmits and receives using user frame register data.
The Q series C24 checks the transmission/reception of following data, using registered data.
(1) Transmission
(a) If user frame transmission is designated, the user frame is converted, or not
converted, from ASCII to BIN data and transmitted, depending on the data
communications protocol, ASCII-BIN conversion designation, and user frame No.
designation, based on the following data as the send data of the given part.
• Register data code 01H to FEH 1-byte data register part
Q series C24 transmission is based on the register code (01H to FEH) data.
Register the data codes 03H, 0DH, 0AH as user frame No. 3E8H: When user frame No. 3E8H is
designated during data transmission, if ASCII-BIN conversion is disabled, the Q series C24 transmits the
data codes 03H, 0DH, 0AH (ETX, CR, LF) as the send data of the given user frame part. If ASCII-BIN
conversion is enabled, the Q series C24 converts each of the data above to 2-character ASCII code data
and transmits.
• Register data code FFH + 00H to FFH 2-byte data register part
The Q series C24 transmission is based on the variable data corresponding to the combination of the register
codes FFH and 00H to FFH.
For example, if sum check code is registered, the Q series C24 will calculate and transmit the sum check code.
If the Q series C24 station No. is registered, the station No. set in the Q series C24 is transmitted.
Register the data codes 03H, FFH, F0H, 0DH, 0AH as user frame No. 3E9H: If ASCII-BIN conversion is
disabled, the Q series C24 transmits the calculated sum check code as the send data of that user frame
part. If ASCII-BIN conversion is enabled, the Q series C24 converts the calculated sum check code to 2
characters/byte ASCII code data and transmits.
