HEC-P6XXX Features

Figure 2-52 - CAN / J1939 Properties

OptiCAN Networking

HEC-P6XXX controllers support the Divelbiss proprietary OptiCAN (CAN Network) protocol. OptiCAN is a register based CAN network

that provides a communications method between OptiCAN enabled controllers and devices (PLC on a Chip based) for transmitting /

receiving variables (integer, boolean, real and timer). The OptiCAN network provides communications with error and status moni

toring of the connected devices.

As OptiCAN utilizes the CAN port, a CAN port must be installed prior to the installation and configuration OptiCAN. For CAN

port installation, refer to the

CAN Networking Ports

Section of this manual.

With a CAN port installed, OptiCAN network must be installed in the ladder diagram project using the EZ LADDER Toolkit Project

Settings Menu.

CONFIGURING OPTICAN IN EZ LADDER TOOLKIT

1. In EZ LADDER, from the File Menu at the top, click

PROJECT

then

SETTINGS

. This will open the Project Settings Window.

Select

HEC-P6000

as the target from the choices.
