As part of a retool, a customer was looking to upgrade their Siemens ET 200x field devices. This legacy hardware was outdated to the point of searching eBay for replacement parts.
The Siemens ET 200pro was specified as the replacement. Patti Engineering completed the programming adjustments and installation.
Aside from solving obsolescence, there were three main benefits to the upgraded field devices:
While this change did have to occur while production was not running in order to replace the hardware, the update went rather smoothly with only a hardware config download and some minor testing. Upfront planning made this possible. During the specification process, the current ET200x components were kept in mind while selecting the new hardware. Each I/O card was individually selected to match the power rating and port numbers to reduce the installation complexity and minimize the conversion and time to the new system.
