Woodward easyYview Series: Technical Analysis of Mini SCADA Remote Control Panel Designed for Generator Sets and Switchgear

Product Overview and Application Fields

Woodward's easYview family is designed for switchgear builders, genset packagers and system integrators as an HMI option for any application where a secure remote control, monitoring, and visualization are desired, such as hospitals, data centers, offshore rigs, landfill and wastewater gas-to-power applications to name a few. This manual describes the easYview family panels: easYview-07-030, easYview-10-150 and easYview-15-150.

The easYview is a touch screen remote control and annunciation panel for use with the easYgen-3000XT or LS-6XT series controls. It is particularly useful with the back panel mounted easYgen-3100XT/3400XT or LS-6XT, providing control from the front panel with greatly reduced wiring to the access door, while keeping high voltage connections located safely on the back panel.

The easYview can be used in Remote HMI mode for remote control and visualization of one easYgen-3000XT or one LS-6XT device. It offers all the HMI resources that the display variants easYgen-3200XT/3500XT offer, but with the state of the art touch screen technology.

Additionally, it offers multi device visualization capability generally referred as SCADA system. It connects to XT-family controllers over Ethernet interface and provides a broad visualization data nodes over Modbus/TCP protocol.

In mini-SCADA mode the easYview offers a system visualization. It can connect up to 3 (easYview-07-30) or up to 18 (easYview-10/15-150) devices at a time. The offthe-shelf easYview HMI solution offers a visualization of four easYgen-3000XT in island or parallel to mains application. The easYview is designed to save customers engineering efforts in field for most common visualization topologies. However, we understand there is no one size fits all solution. Therefore, if your project requirements are not covered by off-the-shelf easYview it is possible to make customizations. 

Core technology architecture and working mode

2.1 Dual working mode design

The easyYview series provides two basic application modes to meet different levels of monitoring needs:

Remote HMI mode: In this mode, easyYview connects to a single easyYgen-3000XT or LS-6XT device through VNC technology to receive and display remote HMI screens. This mode provides all HMI resources identical to the easyYgen-3200XT/3500XT display variant, but utilizes modern touchscreen technology. Depending on the screen size, 1-4 different remote HMI screens can be displayed simultaneously:

7-inch device: supports 1 remote HMI screen

10 inch device: supports up to 2 remote HMI screens

15 inch device: supports up to 4 remote HMI screens

Mini SCADA mode: In this mode, easyYview connects to multiple devices (up to 3 for 7-inch and up to 18 for 10/15 inch) through Modbus/TCP protocol, providing system level visual monitoring. The factory pre installed easyYview HMI solution can display visual information of four easyYgen-3000XT in islanded or grid connected applications, greatly reducing the customer's on-site engineering workload.

2.2 Cascade Function and Multi Device Management

The cascading function of easyYview allows multiple easyYview devices to work together in master/slave configuration. In this configuration, a master easyYview is responsible for establishing remote HMI connections for activities. The slave device sends remote HMI connection requests to the master device, which creates the connection and sends the remote HMI screen to the slave device. This design allows multiple easyYview devices to display the same remote HMI screen, while allowing the master and slave devices to display different remote HMI screens.

Cascade configuration is achieved by selecting the "Use your own IP" option on the settings page:

Main device: Set to 'Yes'

Slave device: Set to 'No' and enter the IP address of the master device
