We have been notified by our vendor that the Trio controller 206/206X, used in many of Joseph Machine Company machines, will be discontinued later this year. Inventory of this controller still remains; but JMC is taking a proactive approach in order to minimize the impact to you, our valued customer.

The discontinuing of the 206/206X will eventually require a conversion to the newer version Trio on affected machines. We recommend adding Trio controllers to your spare parts inventory. We encourage all customers to order replacement 206/206X Trio controllers over the next few weeks, to ensure availability as demand increases.

The conversion plan for replacing the current Trio with the new model (MC405) is complete. The plan involves the following:

  • Physically replace and re‐wire with the new TRIO controller

  • Re‐tune servo(s)

  • Update PLC and HMI programs


It is possible that some of the work required can be completed by plant maintenance personnel; but we recommend a JMC technician be onsite to complete the more technical aspects of the conversion.


Our goal during this time is to make this process as streamlined as possible. In order to manage this conversion properly, and to minimize the impact to the customer, we have assigned a team of resources. As stated above, this WILL require a JMC representative to be onsite. Through a combination of customer and JMC resources, it will be possible to perform the necessary work. In summary, we ask that customers do (2) things.


  1. Order replacement TRIO controllers in the short term

  2. Plan for a JMC technician to complete the conversion as time permits to minimize interruption of production

As always, we value our relationship and hope to work together to get through this conversion.
