I am in need of a user manual for this particular drive. Could anyone provide guidance on how to configure the slave address? A customer is trying to communicate with the drive using Modbus, but our Modbus client is unable to recognize a slave address of 0.
If you are looking for assistance with setting up Modbus TCP on the Unidrive M700, refer to page 97 of the official user manual. Unlike Modbus RTU, Modbus TCP is configured using the IP address instead of a slave address. For further guidance, please consult the manual linked above.
While using TCP, a slave address (unit ID) is still required. It is important to note that the library our software utilizes prohibits the use of a slave address (unit ID) of 0 in TCP mode - it must fall within the range of 1 to 255.
I recently resolved a similar issue for a customer - maybe it's something you're experiencing too. To get it working, set your program to have a slave address of 255. Keep in mind that the CT Ethernet module doesn't have a specific slave address parameter, so it will only respond to address 0 (all), but will only report to address 255. I hope this solution helps!
In response to a customer inquiry, Gene Bond successfully resolved an issue by setting the program (Master) to a slave address of 255. While the CT Ethernet module does not have a specific slave address parameter, it does listen to a slave address of 0 (all) but only reports to 255. This solution has been proven effective and can be implemented for similar cases.

From my experience, a slave address of 0 is typically a broadcast address and not able to be used for specific device communication in Modbus protocol. Perhaps you can try configuring the drive with an unused slave address between 1 and 247 (as this is the typical range for Modbus), and make sure that this address is not conflicting with any other device on your network. The user manual for your specific drive model should have information on how to configure the slave address. If you're unable to locate the manual, providing the exact model number might help us guide you better.
You're right, in Modbus protocol typically a slave address of 0 is used for a broadcast message from the master, meaning it's not typically used for a specific device such as your drive. You might try setting a unique slave address between 1 and 247, which are valid addresses for individual devices. Also, make sure that both the master and the drive, as a slave, are set up to use the same type of Modbus communications, either RTU or ASCII. Do refer to the user manual of the specific drive for details on how to modify the slave address. If you're still having trouble finding a copy of the manual, you can often find them on the manufacturer's website or forums dedicated to similar tech issues.
It sounds like you're dealing with a tricky setup! In Modbus, a slave address of 0 is typically reserved for broadcasting commands to all slaves, which might explain why your client isn't recognizing it. You should check the drive's user manual for the correct range of addresses it supports—often, it will require a unique address between 1 and 247 for each device. If you need to configure that, look for a section in the manual related to communication settings or Modbus configuration. If you can't find the manual, I’d recommend reaching out to the manufacturer’s support; they can provide the best guidance for your specific model.

Answer: - You can download the user manual for the Control Techniques Unidrive M700 from the official website of Control Techniques or contact their customer support for assistance.
Answer: - To configure the slave address for the Control Techniques Unidrive M700 in Modbus communication, you may need to access the drive's settings through its interface or software provided by Control Techniques. Ensure that the slave address is set to a value other than 0 as some Modbus clients may not recognize the address 0.
Answer: - Some Modbus clients have restrictions on using a slave address of 0 as it is commonly reserved for special purposes. To establish successful communication, ensure that the slave address assigned to the Unidrive M700 is a valid and unique value within the Modbus network.
Answer: - If your Modbus client is unable to detect the Unidrive M700, double-check the slave address configuration, network settings, and communication parameters on both the client and the drive. Make
