13 SERIAL COMMUNICATION MODULE DEDICATED COMMANDS
13.5 Programmable controller CPU monitoring function
Data to be stored by response data
■Fixed value
■Programmable controller CPU monitoring function
The send timing (fixed cycle send/condition match send) of the monitoring result is stored. (Page 266 Programmable
controller CPU monitoring function)
■Number of registered word blocks, number of registered bit blocks
The number of blocks of word device information and bit device information are stored. (Page 73 Number of blocks)
■Word device information, bit device information
The information of device, whose monitoring condition is satisfied, is stored for multiple blocks with the consecutive word
devices and bit devices treated as one block.
The following items are stored for each block.
• Monitoring start device: Device code and device number are stored. (Page 67 Devices)
• Number of registered points: Number of device data points is stored in word unit. (Page 72 Number of device points)
• Device data: The device value is stored.
The order of device data differ depending on the setting of "Word/byte units designation" in Engineering tool.
For byte units, handle the word data as 2-byte data and send the numerical values from the lower byte (L: bits 0 to 7).
2 points data of word device (1234H, 5678H)
• Word unit (0)
• Byte unit (1)
■CPU error monitoring, CPU status information
Specify whether to include the result of error monitoring (state monitoring) of the host station CPU module. (Page 267
CPU error monitoring, CPU status information)
• When do not perform CPU error monitoring (0): CPU status information is not stored.
• When perform CPU error monitoring (1): CPU status information is stored.
