CHAPTER 16 USING COMMUNICATION DATA MONITORING FUNCTION
16
16.1 Communication Data Monitoring Function
16.1.2 Communication data monitoring operation
The following describes the communication data monitoring operation.
● When using the communication data monitoring function, the total transmission speed of the two interfaces should not
exceed 115200 bps.
● The communication data monitoring function is effective when the communication protocol is assigned to 0H to 9H.
(1) Monitor start
(a) Monitor start instruction "0001H" is written in the communication data monitoring
specification area (Address: 2018H/2118H). (Set by user)
(b) By the monitor start instruction, the monitor data pointer/monitor data size area are
cleared to 0 and "0002H" is written in the communication data monitoring
specification area which starts monitoring.
*1
(Q series C24 is set.)
(c) When a monitor setting error occurs, "100FH" is written in the communication data
monitoring specification area. (Q series C24 is set.)
Check the monitor buffer head address and the monitor buffer size setting range and perform monitoring again.
*1 Monitor data area (Default address: 2602H to 32FFH/3302H to 3FFFH) is not cleared to 0.
