The incremental encoder module performs high-speed scaling

calculation operations for various industrial applications. The

module interfaces with a FLEX family adapter which then

communicates with a programmable controller processor that has

block-transfer capability and external I/O devices.

The adapter/power supply transfers data to the module (block

transfer write) and from the module (block transfer read) using BTW

and BTR instructions in your ladder diagram program. These

instructions let the adapter read input values and status from the

module, and let you write output values and configure the module’s

mode of operation. The following illustration describes the

communication process.
