Hello Members, I am currently working on a project involving multiple devices connected in a Daisy Chain configuration. During testing, I encountered an issue with fetching data on my Prosoft Data Map from a specific device in the loop. However, after configuring my Port to Enron Daniels, the data was successfully retrieved. My question now is whether this configuration will work with other equipment on the loop, all of which have 16 bit data registers. Additionally, I am puzzled as to why my Prosoft is unable to read the data in two 16 bit registers in its normal settings. Data retrieval only seems possible when I Enable Enron Daniels. Can someone provide further insight on this matter? Your advice is greatly appreciated.
Enron and MODBUS are two distinct entities. The use of the term "ENRON MODBUS" could lead to confusion as they are separate systems.
In response to Mark's comment, it's important to clarify that Enron and MODBUS are not the same entity. The use of the name "ENRON MODBUS" may be misleading. Could you provide further details? I am seeking clarification on this matter.
Check out this concise guide on Enron Modbus and how it differs from standard Modbus, courtesy of Simply Modbus Software. Unsure if the Prosoft device is capable of switching between the two modes? Consult the manual for clarification on this functionality.
zainkt asked for further clarification due to confusion. To elaborate, please refer to the ENRON protocol documents which highlight key distinctions from MODBUS. For instance, the use of a long integer (32 bits) in ENRON protocol only requires one register compared to MODBUS which uses two registers (2 x 16 bit). Note the emphasis on an extension in the original MODBUS protocol. It is important to recognize the various differences between the two protocols.
In the oil and gas industry, Enron Modbus stands out for its use of a single 32-bit register for floating point and long data types, unlike the standard Modbus which uses 2 16-bit registers. Enron Modbus offers a more streamlined approach compared to the standard version, making it a preferred choice for many.
Hello, Your situation seems quite interesting. The Prosoft data map uses Modbus polling which usually handles 16 bit data registers comfortably, so it's unusual that switching to Enron Daniels fixed the issue. Dairy Chain configuration communication protocol often complicates things, so that might be a factor as well. As for your question, whether Enron Daniels will work on other devices in your loop, it largely depends on if these devices support the Enron Daniels protocol. But given that they all have 16 bit data registers, the chances are high. I suggest you conduct some tests to establish compatibility. It's hard to say for sure why you need to Enable Enron Daniels for data retrieval without more information about the specifications of your device and loop, but it's likely due to some specific requirement or setting of the device that isn't met by the standard Modbus polling. Hope this helps!
It sounds like you’ve made some interesting progress with your Daisy Chain setup! The Enron Daniels configuration is often more compatible with certain protocols and can improve communication with devices that might not play well with standard settings. As for the other equipment in your loop, if they also operate with 16-bit registers, it’s worth experimenting with them under the same configuration since there is often variability in how devices handle data requests. Regarding your Prosoft reading issue, it could be related to how those registers are mapped or how data is being interpreted in normal mode—sometimes specific settings are needed for devices that don’t adhere to typical communication protocols. It might help to check the documentation for each device or consult their tech support for more clarity. Good luck with your project!

Answer: - Yes, the Enron Daniels configuration should work with other equipment on the loop that also have 16 bit data registers. It allows for successful data retrieval in such scenarios.
Answer: - Enabling Enron Daniels might be necessary for proper data retrieval if your Prosoft is encountering issues reading the data in two 16 bit registers in its normal settings. Enron Daniels configuration could be providing the necessary compatibility or addressing any communication protocol differences.
