EWCv3.3 Universal Web Kit

[TOC]

Purpose

This document outlines the steps to configure the Universal Web Kit (U-Web kit) based on ESPEC Web Controller (EWC), Version 3, to connect to your existing chamber for control and instrumentation. EWC V3 is capable of communicating and controlling the following controllers: ESPEC P300, SCP220, ES102, Watlow F4 and F4T, Allen Bradley CompactLogix, ControlLogix and Micro8xx series.

Communication between EWC V3 and the existing chamber is accomplished via TCP/IP or USB-to-Serial interface. TCP/IP is the default communication protocol for Watlow F4T and HALT/HASS T-series chambers. Setup procedure for HALT/HASS T-series chambers is discussed in a separate document. The USB-to-Serial interface is for any chamber with ESPEC P300, SCP220, ES102 or Watlow F4.

The U-Web kit consists of the embedded computer in a black box, a DC power adapter, and an Ethernet cable and/or USB-to-Serial converter, as depicted in the following figure. In the setup process, the U-Web kit will be connected to your chamber using the TCP/IP or USB-to-Serial interface and the control PC via a DHCP or static network. The control PC will be used to access EWC via a Web browser to control and operate your chamber.

The DHCP box is checked by default such that EWC is ready to use DHCP when it detects one. The IP address leased by a DHCP server to EWC can be found under the Network Settings submenu (under Settings in the menu bar). If DHCP is not detected (or not available), EWC uses its fallback static IP address (192.168.0.83) as shown in [network-info]. The DHCP box is still checked when EWC uses its fallback static IP settings.

1. Click to continue.

2. The Setup Wizard is complete. EWC now displays its home page in Overview mode and is ready for chamber operation. Single-User or Multi-User:

3. If multiple operators need to control and operate the chamber, they each should have a separate account on the system. Consult our ESPEC Web Controller User’s Manual which can be found in Section 5 for detail on how to create different accounts and privileges for these operators.

   Users may begin to log into EWC to operate the chamber as soon as their account has been created.

4. If this is a single-user system, EWC is now ready for operation. Refer to Section 5 for detail on how to access the online wiki manual or the embedded PDF manual under the About menu.

5 Custom Static Network Setting

A static network other than a Class C type can be set on EWC. The configuration of such static network can be done by using either static or DHCP in Section 3 as a starting point. If your IT requires that each device on the main network must use a static IP address (even on DHCP network), the best approach would be to start from Section 3.

Complete the following steps:

1. Obtain the complete IP information from your IT. Refer to following figure as a example.

2. Log in as admin.

3. Click Settings (in the menu bar).

4. Click Network Settings (in the submenu bar).

5. Uncheck the DHCP box.

6. Edit the IP address field (replacing 192.168.0.83 with a new value). Refer to Figure below as an example.

7. Enter the appropriate values for Net Mask, Gateway, DNS1 and DNS2.

8. Click Save in upper-right corner.

9. Open a new Web browser and navigate to EWC with the new IP address.

Warning! To revert EWC to use DHCP protocol and its preconfigured static network setting, you must check the DHCP box and also enter 192.168.0.83 in the IP address field (and save the settings) before you reboot and connect EWC back to a DHCP or Class C static network. If you failed to apply these settings, EWC will still be using the custom static IP address as its fallback static network protocol.
