(f) Data area bit structure
Because the EW data area is structured as shown below, an operation code and a
status code in it can be used as a ladder contact and a coil, respectively.

When a preset restart is implemented, for example, it can be set either as an
arithmetic function or as a coil as shown below.

(g) Sample
program
y
Operation: Start a motor with an externally supplied start signal and then measure
the pulses generated from an encoder rotating with the movement of the
traveling table to let the motor move to a predefined position and stop.
y
Requirement: Let the program run in the flow shown Figurer 4-10.
