Hello, I am interested in transferring some of our Electronic Overloads from a problematic Devicenet Segment. Do you have any documentation that specifies the maximum number of devices that can be connected in a daisy chain on a drop cable? I am aiming to connect approximately 8 devices on one drop. Thank you, Brett.
Having the right cable length is crucial for optimal performance. A length of 8 on a single trunk line should work well, but be mindful of voltage drop and resistance to ensure smooth operation.
Thank you for responding. All devices are situated within the same MCC, so I believe the total drop length will not surpass 6 meters.
BrettL commented that all devices are within the same MCC, so the total drop length should not exceed 6m. You should be okay with that setup. It's possible to have up to 24 devices on one trunk line. If you need more guidance, refer to the Devicenet bible. Unfortunately, I couldn't attach the bible due to size constraints, but you can easily find it by searching on Google.
I intend to search for the Bible on a secondary line, not the main trunk.
Also referred to as the DeviceNet EncyclopediaOG, this comprehensive source of information is a must-have for those seeking in-depth knowledge about DeviceNet technology.
Hi Brett, from my understanding, the exact maximum number of devices you can connect in a daisy chain can vary depending on the specifics of your setup, such as the power capability of your network and the power requirements of the devices. However, typically it’s advocated to keep it under 6 devices per drop cable for optimal performance. I don't have any documentation on hand, but I'd suggest checking the specifications of your network equipment and the devices you're intending to connect to make sure you don't overload the system. Hope this helps!
Hey Brett, in terms of DeviceNet specifications, typically you can have up to 64 devices on a single network, but the number allowable in a daisy chain is a little less straightforward. It relies more on the total cable length, the type of the cable, and the bit rate rather than the sheer number of devices. If we consider a 250Kbps speed, you can use up to 100m of 'thin' trunkline. So, theoretically, if each of your devices is within 12.5m of each other, you could connect up to 8 devices in one drop. However, remember to allow some room for error and don't cut it too close to the maximum.
Hi Brett, the number of devices that can be connected in a Daisy Chain on a drop cable depends on several factors like the device type, total length of the cable, and potential signal loss, etc. Typically, for DeviceNet systems, 64 devices per network is the limit but you're also restricted by the power supply capacity. That said, connecting 8 devices on one drop should not present any major issues. Always ensure to follow manufacturer documentation for best practices. You might also want to consider using repeaters if you're dealing with long distances. Hope this helps!
Hi Brett, it sounds like you're planning a significant change! While the maximum number of devices on a DeviceNet segment can vary depending on factors like the specific device and cable type, generally, you can connect up to 63 devices on a single bus. However, for a drop cable, you'll want to consider the total length and potential signal degradation, especially with 8 devices. Checking the documentation for both your overloads and the DeviceNet specifications will give you the best guidance. Good luck with the transfer, and hope everything goes smoothly!
Hey Brett! The typical limit for DeviceNet daisy chaining is around 64 devices per segment, but it’s always good to check the specific guidelines for the equipment you’re using since different manufacturers might have slightly different specs. For a drop cable with around 8 devices, you should be fine, but just ensure you're adhering to the overall cable length and termination requirements. If you have the manufacturer's documentation handy, that would be a great reference point! Good luck with your transfer!
