Event Details

OPC Interoperability Workshop, North America


Location: Honeywell, Phoenix

1860 West Rose Garden Lane
United States

Map and Directions



This workshop is “The” event for testing OPC products for interoperability and preparing them for market. Vendors can test and debug their products against one another for interoperability, compliance and reliability. IOP workshops also provide an ideal opportunity to network with your peers, learn about OPC technology and interact with industry-leading experts.

Plan on debugging issues that occur and be prepared to modify your software components if required. Testing will be primarily for the successful operation between clients and servers; we will test for failures as time permits.

Our In-Person and virtual IOPs were very successful, with several members reporting that it was “extremely valuable” in preparing their products for release.

The OPC Interoperability Workshops are open to OPC Foundation member companies only at a cost of US $500 per person. Space is limited, so register now!

Because of the on-going pandemic this event will take place as hybrid event. With the capability to participate in person or virtually we will provide this important testing opportunity again to all our members around the world. This allows our attendees from other regions to participate in the testing. If you desire to participate virtually due to travel restrictions, please book the “Virtual” ticket.

The IOP Workshop, like any event in the US, is subject to the COVID-19 meeting rules in the state of Arizona. Those rules contain requirements for wearing a mask and the health status of the participants.

Note: Because of national restrictions due to COVID-19 in the hosting country, this event may get canceled on short notice. We recommend to use flexible tariffs for your travel arrangements.

Global Discover Service

This workshop will also provide a GDS, which will allow distribution of certificates to OPC UA Clients and Servers. The GDS Supports both Push and Pull methods for obtaining certificates. Both Client and Server vendors are encouraged to test this functionality.

ECC Security

This workshop will also provided testing of new Elliptical Curve Cryptography security algorithms. Vendor that are working on including this functionality are encourage to bring it to this IOP Workshop. If you plan to test this feature, please let us know by sending a mail to iop@opcfoundation.org.

Pub / Sub

This workshop will also support testing of Publish and Subscriber that have implemented the Part 14 pub/sub architecture. Additional details will be provided later. If you plan to test this feature, please let us know by sending a mail to iop@opcfoundation.org.

Available OPC Technology For Testing

  • OPC Unified Architecture (UA) – Windows, Linux, Embedded

Provided Infrastructure For Testing

  • Local Area Network consisting of a standard CAT5 Ethernet cable
  • Internet access
  • Web-based application providing Test suggestions and for recording test results
  • OPC Compliance Test Tool (CTT) – Support

What to Bring

  • Computer (laptops are preferred) containing your OPC product(s) for testing.
  • Backup drives and/or restoration DVDs in the event your PC crashes.
  • Any additional hardware/software needed to conduct your testing.


Interoperability Workshop Preparations

Attendees will be asked to specify their products in the OPC Interoperability Test Application in order to have more time for testing during the workshop. Instructions will be provided in the event payment conformation email.

Monday, 2 May

12:00 – 17:30

  • Network and Computer Setup
  • Verify Connectivity
  • Begin General Testing

We will start with network configuration, followed by GDS interaction [registration/certificate management etc]. This will be done step-by-step with on-screen instructions. After successful configuration all PCs will be part of the test network. A “share” partition on the server will be used to exchange files, if necessary.

Introduction to the infrastructure and the test procedure:

  • All Servers have to be specified by means of a web-based entry form (general properties, supported optional interfaces, supported ItemIDs/Conditions, etc.). This test data will be available for the clients.
  • Clients will also use web-based entry forms to find available servers, view their properties, select them for testing, fill in test results, etc..

Tuesday, 3 May – Thursday, 5 May

08:30 – 17:30

  • General Testing

These three and a half days will be available for general testing. Every client has to perform an IOP test with every server of different vendors. Web-based forms will show the status with respect to available servers and clients.

From past experience, we estimate an average of one hour for each test combination.

Each client vendor must enter the test results for each tested server into a web-based database. The database will be available to all participants at the end of the workshop.

Friday, 6 May

08:30 – 12:00

  • General Testing and wrap-up


Important: Non US-citizens MUST register with Honeywell due to Federal regulations.
Please download the Foreign National Access Registration document and send to iop@opcfoundation.org

Escorted Visitor Access

  • Individuals who require escorted access in a Honeywell facility should show proof of full COVID-19 vaccination.
  • If any visitor cannot show proof of full vaccination, they alternatively may access the site if they:
    • Present a negative COVID-19 test. They must either show an official PCR or Antigen test record not older than 72 hours or attest/substantiate that they have taken an over-the-counter, at-home test not older than 48 hours; or produce an on-site test result, if the Honeywell facility has a testing protocol.
  • In case of emergencies (e.g. urgent site repairs) where those requirements cannot be met, contact the site leader.

Rules Applicable to All Visitors

  • All visitors must follow all site safety protocols in place, including but not limited to onsite testing, masking, and social distancing requirements.
  • The U.S. visitor access protocols will not apply to:
    • Individuals who work off-site and do not require site access.
    • Individuals who come on-site to a Honeywell facility, but do not enter a Honeywell building beyond its access security points – this includes exterior construction,
  • deliveries, ground transportation, and lawn maintenance crews etc.
    • Government officials etc. who are entitled to access a Honeywell facility to perform their official duties such as police, fire department, or first responders.
  • The site may institute a green lanyard or badge holder program for repeat visitors who have unescorted access with a Honeywell badge and show proof of vaccination. Honeywell employees who already have a green lanyard or badge from another Honeywell location will be treated as fully vaccinated for purposes of accessing this location.
