1. Introduction

 

Hi5a Controller’s embedded PLC is a function that implements the common PLC’s function on a Controller. As the below figure shows, by executing HRLadder on a PC or laptop that is connected to a Controller, it is enabled to compose/edit a Ladder program, to download it to a Controller, to upload the Ladder program that are being executed on a Controller, or to monitor the execution status of a Controller. Please refer to the additional function manual for HRLadder.

 

The Hi5a controller I/O can be connected to the upper process control panel through the filed bus or real-time Ethernet. An embedded DeviceNet master can be used to connect DeviceNet slave modules. BD580 or BD58A can be used to connect various devices using physical signals directly. The embedded PLC function controls the output signals that are connected as above with Ladder Logic.
