■Registered word block quantity designation, Registered bit block quantity designation
Designate the number of word device blocks (number of registered word blocks) and the number of bit device blocks (number
of registered bit blocks) registered in C24 as the target when performing device data monitoring or transmission.
■CPU error monitoring designation
Designate whether or not C24 monitors abnormality of the CPU module on the host station (status monitoring) in the
programmable controller CPU monitoring.
■Monitoring device designation, start device number designation, number of read points
designation
When performing device data monitoring or transmission, designate the device range for each block for the number of blocks
designated by "Registered word block quantity designation" and "Registered bit block quantity designation".
The target of device data monitoring for condition match send is the start device for each block.
Word device designated block: Head word device (for one word)
Bit device designated block : Head bit device (for one bit)
• The monitored device is the item that indicates the target device of the corresponding block and designated with the codes
below. (Page 122 List of device code)
• The start device is the data that designates the head of the target device range for the corresponding block.
• The number of read points (number of registered point) is the item that indicates the target device range for the
corresponding block which designate points from the start device number.
The bit device designates points in word units (1 point = 16 bits).
• The methods for designating these data are the same as the designation methods used when reading from or writing to the
device memory, which are described in the following manual.
( MELSEC Communication Protocol Reference Manual)
When the user performs the programmable controller CPU monitoring registration, the device No. will
designated in either a decimal or hexadecimal depending on devices. The number of read points (number of
registered points) are designated in hexadecimal.
However, for data communication using either MC protocol (format 1 to 4) or nonprocedural protocol, when
ASCII-BIN conversion of the communication data has been designated, the start device number for all devices
to be transmitted to target devices as the monitoring results will be converted to hexadecimal ASCII data and
transmitted.
■Monitoring condition specification (Judgment condition specification)
When the condition match send is designated by the "Programmable controller CPU monitoring function designation",
designate the conditions for transmitting information for the "Monitoring condition value designation".
■Monitoring condition value designation
When the condition match send is designated by the "Programmable controller CPU monitoring function designation", this
data designates the status/numeric value for "Monitoring condition specification (Judgment condition specification)".
• When the monitoring device is a word device: Designate the monitoring condition value with a numeric value
• When the monitoring device is a bit device : Designate the monitoring condition with a numeric value (1/0) corresponding to
ON/OFF.
