9.2. Relationship between the Destination Device and the Global Variables
Global variables must be sorted in order of offsets of the destination device when setting the
tag data link parameters.
The relationship between the memory allocation (offset) of the destination device and the
global variables are shown below.

ERCLR
EXE: Control command execution bit: Turns ON when the Controller
instructs execution of control commands to the displacement
sensor.
SYNC: Measurement synchronous start bit: Turns ON when the user
Controller instructs measurement synchronization to the
displacement sensor.
ERCLR: Error clear bit: Turns ON when the displacement sensor ERR
signal turns OFF.
