6.2 Programmable Controller CPU Monitoring Function
Data arrangement of device information and programmable
controller CPU status information
When user frame numbers B001H to B00AH are designated (example for one block)
■When word device data (W100 to W103, (4 points)) is transmitted
When the word/byte units designation is set to word unit, the device data will be transmitted in the order of (H)(L).
The number of registered points is the number of points in word units.
• (When ASCII-BIN conversion is not performed)
The total number of bytes for the device data portion is the number of device points 2.
• (When ASCII-BIN conversion is performed)
The total number of bytes for the device data portion is the number of device points 4.
When the word/byte units designation is byte
When the word/byte units designation is word
When the word/byte units designation is byte When the word/byte units designation is word
