Is the Micro800 compatible with an SMC EX260-SEN1 for seamless communication? A customer has inquired about this, seeking to incorporate our solenoid valve panels, which utilize the SMC EX260-SEN1, into their projects. While the Micro800 series appears to offer support for Explicit messaging, uncertainty remains regarding the compatibility of the EX260-SEN1. Any insights or experiences on this matter are appreciated, especially given the popularity of the SMC EX260-SEN1 in industries like Food and Beverage.
Hello theColonel26, though I am not well-versed in Micro800, I will address your query regarding the SMC EX260-SEN1 and its support for explicit messaging. According to the datasheet of the SMC device (https://www.smcworld.com/assets/manual/en-jp/files/EXxx-OMP0013.pdf), it is stated that the device supports EtherNet/IP adapter functionality. In the context of EtherNet/IP, an adapter will have its process data mapped to instances of the assembly object (class ID 0x04). Although I have not examined the specific mapping for the process data on SMC devices, if the SMC functions as a standard EtherNet/IP adapter and the Micro800 supports client explicit messaging, one should be able to retrieve the data using GetAttributeSingle (service IP 0x0e) for class ID 0x04 (Assembly object), instance ID (corresponding to the SMC's process data), and attribute ID 0x03 (data). In the absence of an EtherNet/IP scanner communicating with the SMC, the use of SetAttributeSingle (service ID 0x10) will enable the client to update process data as well. I hope this explanation proves beneficial to you.
Thank you, Alfredo, for your input. I came across some information stating that implicit messaging corresponds to a Level 1 connection, while explicit messaging corresponds to a Level 3 connection. I have successfully connected to SMC Valves through RS Studio 5000 Desiger and Codesys using the Device tree configuration Method. However, neither configuration specifies the Connection "Level" being utilized. Are you familiar with this aspect, or do you have any suggestions on how I can determine it? I am simply curious to know more about it.
This article delves into the topic of implicit and explicit connections in industrial automation, specifically in the context of Ethernet/IP and DeviceNet specifications. In simpler terms, an implicit connection, known as Class 1, involves automatic cyclic exchanges of data between devices in a device tree. On the other hand, an explicit connection, referred to as Class 3, requires a specific function code for communication, often triggered by an MSG instruction. Understanding the differences between Class 1 and Class 3 connections is crucial for optimizing industrial automation systems.
I believe plvlce's answer is spot on. There is nothing more to contribute to this discussion.
When it comes to scanning for responses, the term "scanner" often brings to mind constant polling, similar to how Modbus operates. However, my understanding is that with Class 1 protocols, this isn't necessarily the case. In Class 1, the cyclic service running in the background may utilize a standard EIP function for outputs. It's important to note that Class 1 inputs do not involve constant request and response cycles. Instead, when a scanner initially connects, it requests a continuous stream of updates from the adapter at a set frequency. Subsequently, the adapter will continuously send updates via UDP at a specified interval. This leads me to question the distinctions between Class 1 and Class 3 at the Layer 4 TCP/UDP level.
In my experience, the Micro800 PLC series should theoretically be capable of communicating with SMC EX260-SEN1 via Modbus TCP or Ethernet/IP. However, the setup could be intricate since mapping registers correctly is essential for seamless communication, and this does require specific knowledge. I do recommend reaching out to SMC and Rockwell Automation technical support to get a precise answer. They might have application notes or guides to follow. Remember, every application is unique and sometimes better efficiency can be achieved through alternative solutions besides a direct interface.
From my personal experience working with similar setups, Micro800 controllers should ideally be able to communicate with the SMC EX260-SEN1 through EtherNet/IP. However, it's important to ensure that you've configured the output assembly instance correctly in the controller, and that the EX260-SEN1 is accepting the message type that the Micro800 is sending. It's a bit tricky but definitely doable. I've seen it successfully implemented in a few packaging lines before. Always recommended to do a small scale testing before full integration.
