2.2 About the Programmable Controller CPU Monitoring Function
• When user frame No. B061H is designated
Programmable controller CPU status information (for one block) is sent as the following data:
(When ASCII-BIN conversion is not performed)
The total number of bytes for the device data section is the number of device points  2.
(When ASCII-BIN conversion is performed)
The total number of bytes for the device data section is the number of device points  4.
• When user frame No. B080H is designated
The transmission block count will be sent as follows:
Number of registered word blocks: 2 (D0 to D3 (4 points), W100 to W107 (8 points))
Number of registered bit blocks: 1 (M0 to M31 (2 points))
