Description
Counts 0 to 32,767
The setting can be changed between the
latched (battery backed) type and the non-
latched type using parameters.
−2,147,483,648 to
+2,147,483,647 counts
The setting can be changed between the
latched (battery backed) type and the non-
latched type using parameters.
*3
The setting can be changed between the
latched (battery backed) type and the non-
latched type using parameters.
Among the 7488 fixed latched (battery
backed) type data registers, D1000 and later
can be set as file registers in units of 500
points.
latched (battery backed)
Available only while a memory cassette is
mounted
For HSCS instruction
For MC instruction
