Data Exchange; Introduction - Omron trajexia CJ1W-MCH72 Operation Manual

Introduction

3-1 Introduction
The CJ1W-MCH72 can exchange data with memory areas in the PLC. This
enables the CJ1W-MCH72 to use the inputs and outputs connected to the
PLC. Also, programs in the CJ1W-MCH72 and PLC programs can exchange
control and status data.
Because the CJ1W-MCH72 can only access the input and output data via the
PLC, the data exchange requires an extra PLC cycle.
This section describes the issues related to cyclic data exchange.
