16.2 Communication Data Monitoring Function Settings
(2) Buffer memory for communication data monitoring function
(a) Communication data monitoring specification area (Address: 2018H/2118H)
Set start/stop of the communication data monitoring.
See Page 359, Section 16.1.2 for communication data monitoring setting operation.
(b) Monitor option specification area (Address: 2019H/2119H)
Specify the options of the communication data monitoring function.
• Action for buffer full (bit 0)
• When action for buffer full is OFF: When the monitoring data exceeds the capacity of the monitor data
area, monitoring continues by writing the new data over the oldest data.
• When action for buffer full is ON: When the monitor data area is full (monitor buffer size), monitoring is
automatically stopped and "1002H" is written in the communication data monitoring specification area.
(Set by the Q series C24)
• Stop by timer 0 error (bit 2)
• When the stop by timer 0 error is OFF: Monitoring continues even if the timer 0 error (error code 7F40H)
occurs.
• When the stop by timer 0 error is ON: When the timer 0 error (error code 7F40H) occurs, monitoring is
automatically stopped and "1002H" is written in the communication data monitoring specification area.
(Set by the Q series C24)
(c) Monitor buffer head address specification area (Address: 201AH/211AH)
Specify the head address of the storage area (monitor data area) for the monitor data within the range of the
user's free area of the buffer memory.
Setting range: 0400H to 1AFDH, 2600H to 3FFDH (Default: 2600H/3300H)
(d) Monitor buffer size specification area (Address: 201BH/211BH)
Set the size of the monitor data area.
Setting range: 0003H to 1A00H (Default: 0D00H)
