CHAPTER 2 USING THE PROGRAMMABLE CONTROLLER CPU MONITORING FUNCTION
2
2.2 About the Programmable Controller CPU Monitoring Function
(d) When sending the monitoring results as data during condition agreement
transmission, head data (header) and end data (footer) for the on-demand function
are added to the device information for a block with matched monitoring conditions
and the programmable controller CPU status information upon the occurrence of an
error. The header and footer are added to each clock, and then the monitoring result
data is transmitted.
Results are sent in the following order: The programmable controller CPU status information, the device
information registered in the word block and then the device information registered in the bit block.
When there is communication using the MC protocol form 1) to 4), all of the device monitoring head device number will be
converted to hexadecimal ASCII data and sent. (The same conversion is performed during either constant cycle
transmission or condition agreement transmission.)
