(g) Monitoring device, head device No., read point (Number of registered points)

When performing device data monitoring or transmission, designate the device range for each block for the

number of blocks designated by number of registered word blocks and number of registered bit blocks (

Page 61, Section 2.3.1 (3) (e)).

*1 The target of device data monitoring for condition agreement transmission is the head 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 listed in Page 38, Section 2.2.2 (4).

• The head device is the data that designates the head of the target device range for the corresponding block.

• The read point is the item that indicates the target device range for the corresponding block which designate

points from the head device No. 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 MELSEC Communication Protocol Reference

Manual.

Remark

When the user performs the programmable controller CPU monitoring registration, the device will designate either a decimal

or hexadecimal device No. The read points (registration points) are designated as hexadecimal.

However, if this is done by either MC protocol communication (form 1) to 4)) or non procedure protocol communication,

when ASCII-BIN conversion of the communication data has been designated, the head device No. for all devices to be sent

to external devices as the monitoring results will be converted to hexadecimal ASCII data and sent.

(h) Monitoring condition

When condition agreement transmission is designated with the programmable controller CPU monitoring

function ( Page 61, Section 2.3.1 (3) (c)), designate the conditions for transmitting information for the

monitoring condition value ( Page 62, Section 2.3.1 (3) (i)).

(i) Monitoring condition value

When condition agreement transmission is designated with the programmable controller CPU monitoring

function ( Page 61, Section 2.3.1 (3) (c)), this item designates the status/numeric value of the monitoring

condition ( Page 62, Section 2.3.1 (3) (h)).

• 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.
