Range
For using the PLC link, check the checkbox.
Specify a unit number for the own unit. When setting it using a user
program (PMSET/pPMSET instruction), specify "0". The unit
number selector on the front panel of the unit needs to be set to
00.
Set the starting word number of a device used as hold type. The
holding start number is specified as a relative value from the
beginning of "Relay Link Area" and "Data Link Area".
For link relays: 0-256
For link registers: 0 to 4096
Example 1) When specifying 0, the area in the selected range is
hold type.
Example 2) When specifying the maximum value, the area in the
selected range is non-hold type.
Specify the unit to refresh the I/O by the PLC link in the format of
(set value x 256 bytes/scan). By default, all points are refreshed
collectively when specifying 0. Although the responsiveness is
improved, the scan time of a single unit becomes longer. When a
set value is changed, data of the set number of bytes is refreshed
for each scan. Although the responsiveness is deteriorated, the
scan time of a single unit becomes shorter.
