Discussion Overview

The discussion revolves around finding inexpensive MODBUS devices suitable for medium-scale compatibility testing with a new controller. The focus is on identifying affordable alternatives to more expensive products from established manufacturers like Schneider Electric.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about inexpensive MODBUS devices for testing purposes, expressing a desire for alternatives to pricier options.
  • Another participant shares a resource link that lists MODBUS devices, suggesting it may assist in finding suitable products.
  • A third participant acknowledges the shared link and indicates they will forward it to their testing group.
  • A fourth participant provides a link to Automation Direct, recommending it as a potential source for affordable MODBUS products.

Areas of Agreement / Disagreement

Participants appear to agree on the need for inexpensive MODBUS devices, but there are no settled conclusions on specific products or sources.

Contextual Notes

The discussion does not specify the criteria for what constitutes "inexpensive" or the specific requirements for compatibility testing, leaving those aspects open for interpretation.

Who May Find This Useful

Individuals or groups involved in system testing, particularly those working with MODBUS protocols and seeking cost-effective solutions.

Does anybody know of inexpensive MODBUS devices that we can purchase for some medium-scale compatibility testing with a new controller that we are building? There are some moderately expensive products from Schneider Electric, but we're hoping to find some more "jellybean" products that we can try out in our System Testing. Thanks.

Thanks @jedishrfu I'll pass that link along to the test group.
