Why One Automation End User Chose Bedrock OSA® Remote

June 4, 2018
Robert Bergman

We asked one of the first people to order a Bedrock OSA® Remote what he was hoping to get from it. Here is what Jason Hamlin, Process Automation Manager for the Lynchburg, Virginia Regional Wastewater Treatment Plant, said:

Security, soft-selectable I/O, programmability and ruggedness
“I am super-excited about the prospects for the Bedrock OSA® Remote. The security alone is worth the price of admission, but if I factor in the soft-selectable I/O, programmability and ruggedness, there is nothing else even close.”

Extending control to more remote areas
“I will be able to extend control to more remote areas because the encrypted communications are built in. I trust the Bedrock products because I know they are implementing today’s best cyber security practices. The root certificates and encrypted procedures they use are based on the same principles that protect online banking. If those don’t work; we are all in trouble.”

Operation in extreme temperatures
“I love the fact that the system is rated for temperatures as high as 80 degrees C. I can build out a control panel and not have to worry about adding a panel air conditioner. I can put it in a fiberglass box, set it in direct sunlight and it would be fine.”

Multi-function capability in a small form factor
“I like the small form factor and the fact that everything is built in. Having logic built in is a great advantage over say a radio I/O, which is essentially dumb. Even though the radio may have some encryption I would still have to bring the signal back to the plant through a firewall, because I have no control over what someone might do to it in the field.”

“With OSA Remote, however, I will have full PLC programming capabilities. I can set an edge device to start a pump if the water level is too high and to shut it off if the level is too low. I can program all of this to happen natively or to report the status back to me so I could manually control the pump as I see fit.”

Ethernet connectivity
“I will use that Ethernet gateway to connect to legacy devices. I could install the OSA® Remote on an existing pump station; and have access to 10 or 20 channels of I/O. And if I already have some drives or controllers out there already, I can use an OSA® Remote as a secure proxy. I would connect existing controls via the Ethernet port and have a stopgap security measure until we migrate all PLCs to the Bedrock OSA®. The Bedrock OSA® Remote will read and control the legacy devices, translate their data into encrypted OPC UA and provide a security layer between what happens in the field and my main SCADA system.”

Getting ahead of regulations
“There is growing realization that we have to secure our critical infrastructure but no one has the budget to move quickly on it. Cyber security regulations and standards are evolving slowly in the water industry, but my strategy is to get out ahead of coming regulations, so when they do come out we are already there.”

Supporting open standards
“There are a lot of proprietary 1-off cyber security protection products out there. Bedrock is not proprietary in the sense that they are using industry standards and best practices for embedding cryptographic identities in the firmware of their chips.”

Much more than a firewall
“OSA® Remote is not designed to be a firewall but it provides that functionality and much more. A firewall traditionally provides a series of rules that govern which traffic is allowed and which is blocked. But with OSA Remote I will be getting additional control functions, and cyber analytics including anomaly detection, as well as the intrinsic authentication and encryption functionality.”

The benefits of programmability
“I can trigger events off of the cyber analytics functionality. If I detect suspicious activity on a port – like a denial of service attack – I could shut that port down and check back on it later. While the PLC functionality keeps the rest of the process running, my main SCADA system would send me a message that a port is shut down, so I can tend to it. Getting this kind of functionality without OSA® Remote would require at least three other devices. And with everything built into the module, there is a lot less integration required to tie it back into the main control system. This saves money and increases reliability.”

I/O, logic, security and software in one compact, economical package
“I could have spent less for remote I/O but it wouldn’t have any logic, cyber security or the robustness of the Bedrock system. I could get a low-end I/O engine with some programmability, but I wouldn’t get advanced cyber security. And there are plenty of low cost cyber security appliances out there, but none that have I/O or logic control. With Bedrock, for a very reasonable price, I get it all, along with free, enterprise class software.”

Soft-selectable I/O saves costs
“Soft-selectable I/O is fantastic. I can get 10 or 20 channel of I/O and can pick and choose what I want them to be. If you deploy a mainstream PLC on a very simple pump station, for example, you would need a couple of digital inputs, a couple of analog inputs and a couple of analog outputs. To achieve this, you would need three different I/O modules, just to achieve that mixture, even though you really need only 10 total channels. With the OSA® remote, I only have to buy a single integrated device with 10 channels and I can program them to do almost anything I want.”

Flexible resolution and scan times
“I can change the resolution and scan times on my analog I/O; can switch between 4-20 and 1.5 volts or 0 to 10 volts. On the same card I can mix a 0-5 volt potentiometer input for speed control and output it to a 4-20 I/O for feedback on the 4-20 input on the pump, and I can do all of that on one 10-channel OSA® remote. Doing that with most other platforms would require 3 separate I/O blocks.”

Surge protection
“There is also some surge suppression with the OSA® remote. You don’t have to add it externally to your panel. You can wire directly to it and it will quench any surges that may happen. This saves costs in panel building because you don’t have to add extra components. If you are putting a pump in a remote pump station, you will want surge suppression on every piece of I/O because you would rather blow up a surge suppressor than smoke a PLC card. But unless the PLC has surge suppression built in – or is otherwise rated to handle a 1200 volt surge, you are going to need external surge suppressors.”

Why try to make one when you can buy it for less
“I haven’t seen a disparate set of components that I could easily assemble to rival every feature set of the OSA® Remote. And who has the time to look for that anyway? When someone comes along and says here is the product that does everything you want – why spend time trying to research and compare all the options out there? And the more I/O you need, the more challenging it becomes to replicate that functionality, but not with Bedrock.”
