Buffer memory for send/receive data monitoring function
Send/receive data monitoring designation (Un\G8216/8472)
Designate the start/stop of the send/receive data monitoring function.
For details on the send/receive data monitoring designation operation, refer to the following section.
Page 388 Send/receive data monitoring operation
Monitor option specification (Un\G8217/8473)
Designate the options of the send/receive data monitoring function.
■Stop at buffer full specification (bit 0)
• When the stop at buffer full specification is OFF
When the monitored data exceeds the monitor data area size, monitoring is continued by writing new data over the oldest
data.
• When stop at buffer full specification is ON
When the monitor data area is full (monitor buffer size), monitoring is automatically stopped and "1002H" is written in the
send/receive data monitoring designation area. (Set by C24)
■0 timer error outbreak stop designation (bit 2)
• When the o timer error outbreak stop designation is OFF
Monitoring continues even if the timer 0 error (error code 7F40H) occurs.
• When the 0 timer error outbreak stop designation is ON
When the timer 0 error (error code 7F40H) occurs, monitoring is automatically stopped and "1002H" is written in the send/
receive data monitoring designation area. (Set by C24)
Monitor buffer start address designation (Un\G8218/8474)
Designate the start address of the storage area (monitor data area) for the monitored data within the range of the user setting
area of the buffer memory.
Setting range: 0400H to 1AFDH, 2600H to 3FFDH (Default: 9728/13056 (2600H/3300H))
Monitor buffer size designation (Un\G8219/8475)
Designate the size of the monitor data area.
Setting range: 0003H to 1A00H (Default: 0D00H)
