Exploring Automation Direct Stride I/O Compatibility with AB Logix PLC

johnd_125 shared his extensive experience of over 25 years working with various PLCs such as AB SLC, Micro, and Logix. Despite being comfortable with his current programming environment and having a library of reusable code, he is open to exploring cost-saving options for I/O hardware. One such option he is considering is Automation Direct's Stride I/O, known for its affordability and ease of use, especially with Modbus TCP capability. He is curious about the compatibility of Stride I/O with CompactLogix, which also supports Modbus TCP. While traditional PLC manufacturers like AB may downplay the idea, he believes it is worth investigating for potential benefits. He seeks insights from others who have used this setup and their outcomes. For those considering EtherNet IP, johnd_125 suggests looking into Beckhoff's BK9105 bus coupler and their "KL" series I/O modules for seamless integration into RSLogix. While the range of I/O modules may be limited to the "KL" series, they offer a wide variety at cost-effective prices with a compact design for efficient use in control panels. Beckhoff may also have solutions for Modbus TCP, reflecting their comprehensive range of offerings for various scenarios. Those looking to expand I/O on a RSLogix platform with Beckhoff I/O have multiple options to explore, with the BK9105 being one potential approach.

I have experience using the ControLogix system in conjunction with Beckhoff IO for a compact subsea application. It is functional, but requires the use of KL modules. One challenge is determining the length of the connection due to varying card lengths and headers. Troubleshooting individual channels is difficult, as removing a single card from the remote IO results in the loss of the entire string. In hindsight, I would opt for Beckhoff or CODESYS PLC paired with Beckhoff IO for a more seamless and reliable solution.

Siemens ET200SP is compatible with Ethernet/IP through a "multi-fieldbus" interface module available on the Siemens website. This module allows you to utilize the entire ET200SP product range, excluding safety components. It is worth noting that the ET200SP i/o modules are equipped with push-in terminals, which may not be preferred by some users who prefer cage-clamp or screw terminals. I suggest using the TIA selection tool, provided by Siemens, to help you determine the best components for your application. In addition to Siemens, Omron also offers i/o modules designed for use with Ethernet/IP.

Thank you for the recommendations. To test the capabilities, I decided to explore the Automation Direct Stride I/O line. I purchased an 8-channel thermocouple module (SIO-MB08THMS) and a Combination Discrete Module (SIO-MB12CDR), and set them up on a benchtop for testing. The configuration process was straightforward, with helpful documentation provided with each module. I connected the thermocouple module to a Wonderware application using the DASMBTCP driver in the SMC. While I had limited experience with Modbus, I managed to figure it out with some effort. I then proceeded to connect both Stride modules to a 1769-L2 CompactLogix using the Modbus TCP Client AOI from RA. This required some additional troubleshooting, but with the help of a manual and online resources, I successfully integrated the modules with the PLC. As a simple test, I linked an output of the Stride to one of its inputs, and replicated the same setup on the local I/O of the CompactLogix. The results showed a significant difference in response time, with the Stride I/O performing much faster at 170ms compared to the local I/O delay of 43 seconds. Despite encountering a limitation in adjusting the poll interval, I was overall satisfied with the performance for most applications. Additionally, the Stride modules feature a watchdog function, which would be beneficial in real-world scenarios. In conclusion, while the Stride I/O with CL setup may feel somewhat basic, it proved to be reliable. For future projects involving non-Rockwell I/O, I would consider exploring Ethernet IP options from manufacturers like Beckhoff and Wago, as suggested. Thank you for your insights.

The AOI has a poll interval that I attempted to decrease to 10ms, but it only accepted a minimum of 80ms for some unknown reason. I will need to further investigate this limitation. Despite this, a poll interval of 170ms is still satisfactory for most applications. It is important to note that the minimum limit of 80ms is hardcoded for a specific purpose. Each poll interval requires a minimum of 8 scans for reliable processing. To achieve a 10ms poll interval, the task rate must be 1.2ms, which is lower than the AOI execution time of approximately 2ms in Compactlogix from what I recall.

I am curious, what is the monetary savings in raw dollars?

The potential savings are attractive, but the ease of use is essential. When comparing prices, it ultimately comes down to what you are comparing it to. At $172 USD for 16 points of I/O, the STRIDE modules offer a competitive price point. However, it's important to note that these modules are not expandable. If you only require 16 points, the STRIDE modules are a cost-effective option compared to Point I/O. But if you need more points, the savings may not be as significant. Despite this, the STRIDE modules are still a convenient choice to consider.
