■Send user frame designation
The following explains the purpose of the buffer memory to be used when transmitting data using user frames, along with the
designated and stored values.
• 'Sending user frame' (Un\G182/342)
In data communications using a user frame, what number of the send frame number designation area is being sent is
stored.
Buffer memory address
0H( 0): Not sent
1H to 64H( 1 to 100): User frame being transmitted designation No. (nth number)
• 'CR/LF output designation' (Un\G183/343)
When transmitting a user frame or arbitrary data that does not contain CR/LF, designate whether or not a CR+LF will be
sent each time a user frame or arbitrary data is sent.
Buffer memory address
• 'Output start pointer designation' (Un\G184/344)
Write the head position (th) in the send frame number designation area for writing the registration number of the user
frame to be sent.
However, transmission using a user frame is not performed when the value of the output start pointer designation area is
"0".
Buffer memory address
• 'Output quantity designation' (Un\G185/345)
Write how many user frames are transmitted from the designated position in the output start pointer designation area.
However, transmission is not performed and completed normally when the value of the output quantity designation area is
"0".
