Here, commands are explained that are used by the Display in Extend Mode, when using [1:n ASCII], [1:n Binary] or 2-wire type communication, to output an interrupt code via the Display unit's Memory Link's Absolute Value Write, etc. from the Display unit to the Host.
When using 2-wire type connection, be sure to perform the following settings even for a 1:1 connection.
Marked area with asterisk (*) may not be added depending on the setting.
When there is no error
Marked area with asterisk (*) may not be added depending on the setting.
If an error occurs
NAK response
<Setting range>
Number of data packets
When a request command is sent from the host, this value defines the previously issued interrupt output's number of data items.
When all the previously issued interrupt output data is acquired, this data frequency (number) must be sent.
Data
The data (00H to FEH) is converted into a 2-digit ASCII code (HEX) before being output.
"00" will be entered in this field if there is no data to be output.
Marked area with asterisk (*) may not be added depending on the setting.
When there is no error
Marked area with asterisk (*) may not be added depending on the setting.

NAK response
<Setting range>
Number of data packets
When a request command is sent from the host, this value defines the previously issued interrupt output's number of data items.
When all the previously issued interrupt output data is acquired, this data frequency (number) must be sent.
Data
The data value (00H to FEH) is output.
"00" will be entered in this field if there is no data to be output.
<Example>
"0031H" is written to address 13 in the Memory Link by the Word Switch (touch panel input).
ETX. SUMCHECK: ENABLED, TERMINATOR: CR.LF, ACK: ENABLED, NAK: ENABLED
*1: When the host sends an ESC I command, the Display sends the response data block containing 0 in the Number of data packets field and the data field. However, be sure to use the ESC I command when using the 2-wire type.
<2-Wire type>
ETX. SUMCHECK: ENABLED, TERMINATOR: CR.LF, ACK: ENABLED, NAK: ENABLED
ETX. SUMCHECK: ENABLED, ACK: ENABLED, NAK: ENABLED
*1: When the host sends an ESC I command, the Display sends the response data block containing 0 in the Number of data packets field and the data field. However, be sure to use the ESC I command when using the 2-wire type.
<2-Wire type>
ETX. SUMCHECK: ENABLED, ACK: ENABLED, NAK: ENABLED
