Number of points
assigned for ZR
(extension)
• Stores the number of points set for ZR device (excluding the number of
points set for the extended data register (D) and extended link register
(W)). The number of points is stored in this SD only when 1k or more
points are set for the extended data register (D) and extended link

• Stores the total number of points set for the data register (D), which is an
internal user device, and the extended data register (D) (in 32-bit binary
data).
SD309
SD310
Number of points
assigned for W
(in

processing
Time reserved for
communication
processing
• Reserves the designated time for communication processing with GX
Developer or other units.
• The greater the value is designated, the shorter the response time for
communication with other devices (GX Developer, serial communication
units) becomes.
• If the designated value is out of the range above, it is processed that no
setting is made.
• Setting range: 1 to 100 ms
• Note that the scan time becomes longer by the designated time.
