6 USING THE PROGRAMMABLE CONTROLLER CPU MONITORING FUNCTION
6.2 Programmable Controller CPU Monitoring Function
When user frame No. B061H is designated
Programmable controller CPU status information (for one block) is transmitted as the following data:
• (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 user frame No. B080H is designated
The transmission block is transmitted 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))
