Reserve Your Seat TodayI met a potential client at DistribuTECH in Orlando in the last week of February. His primary interest was avoiding planned obsolescence anywhere in his infrastructure.
Planned obsolescence is using equipment made from highly degradable material that doesn't last very long.
Planned obsolescence could be a strategy for some manufacturers to encourage repeat purchases from their customers in the short term.
The problem with that is that you will continually be forced into frustrating and expensive replacement or upgrade costs that will hamper your ability to grow.
There are several steps you need to take to find a SCADA & Telecom manufacturer that understands the value of long-term reliability and doesn't try to force you into a planned obsolescence trap.
My client wanted to be sure that DPS wouldn't force an "upgrade" to enable TLS 1.2 for his current NetGuardian (DPS Telecom's RTU) web interfaces.
If you run into a manufacturer that is willing to do that, you should recognize that it's not a one-time event. They will most likely keep forcing you to get certain upgrades to have access to better features.
In October 2007, DPS sold the first NetGuardian 832A G5. The initial development, as with most of our devices, was guided by needs that are often reoccurring among our clients.
When equipped with an internal accelerator board, a G5 RTU supports SSL encryption for an encrypted HTTPS web interface. The previous G4 only supported unencrypted HTTP.
After 2008 the G5 became the new standard for new NetGuardian 832A installations.
The important part, however, is that the G4 remained available for clients that have been using it as a standard for 10+ years.
All users of the G5 had a total of 103 free firmware upgrades for its entire life cycle that spanned from 2007-2020.
My client understandably was worried about having to upgrade from a G5 to a G6 after only 5 years of dealing with DPS Telecom equipment.
I explained that they were at the end of a long life cycle when they purchased their equipment and that this is easily overcome with large, no-questions-asked trade-in discounts.
DPS delivered the first G6 model of the NetGuardian in November 2021. This upgrade came about due to clients constantly requesting TLS 1.2 security and local MODBUS and SNMP processing.
The G6 also had a much faster processor than the G5 after 14 years of industry evolution. This eliminates the need for internal accelerator boards and also enables modern TLS 1.2 encryption that is often required.
Due to my client reflecting similar needs in addition to increased library storage and processing requirements, they went with the G6.
DPS clients constantly find the world changing around their NetGuardians in the field due to them lasting anywhere from 10-20 years.
The "world change" in the last 7 years that caused our clients to upgrade to a G6 was the increasing prevalence of the TLS 1.2. This started when certain browsers refused to connect to older algorithms.
Our clients were encouraged by DPS Telecom's no-questions-asked 30% RTU trade-in discount offer.
After satisfying my client's final request of supporting custom security certificates for compliance reasons, they were happy with the conclusion that we reached and we've been providing them with in-depth documentation, as well as customer support that is actively helping them install DPS equipment.
