CHAPTER 2 USING THE PROGRAMMABLE CONTROLLER CPU MONITORING FUNCTION

2.2 About the Programmable Controller CPU Monitoring Function
2.2.2 Programmable controller CPU monitoring information
This section explains the monitoring target information used to execute the programmable controller CPU monitoring
function.
(1) The following information can be registered as the target of the programmable
controller CPU monitoring function.
(a) Device monitoring for the local station's programmable controller CPU
• Monitoring of the numeric values stored in the word device
• Monitoring of the bit device ON/OFF status
(b) Monitoring of the local station's programmable controller CPU status
(2) In monitoring word and bit devices, a maximum total device point value of 960
(equivalent to a maximum of 15360 bits for only bit devices), or a total of 10
blocks when any continuous device range comprises one block, can be
registered. Since monitoring of the local station's programmable controller
CPU status will also be registered as a one-block portion, up to 11 blocks can
be registered.
11 (Number of word device blocks registered + number of bit device blocks registered) + CPU status monitoring
(1 block)
960 points (Total number of all word device block points (1 point = 1 word) + total number of all bit device block
points(1 point = 16 bits))
(3) With device monitoring of the blocks for which the word and bit devices are
registered, the head device of each block becomes the monitoring target.
For a block in which 10 points of word devices from D100 to D109 are registered
Monitoring target: Numeric value stored in D100
Data transmitted: Numeric values stored in D100 to D109
For a block in which two points of bit devices from M100 to M131 are registered
Monitoring target: ON/OFF status of M100
Data transmitted: ON/OFF status of M100 to M131
