About this driver
Modbus/TCP is an open communication protocol proposed by Modicon, Inc. Therefore, if you use equipment that supports the Modbus/TCP standard of other companies, you may be able to connect with this driver.
However, since our drivers are developed targeting Modicon devices, in some cases they may not be able to connect to devices made by other companies. Therefore, if you are communicating with other companies' Modbus/KTCP-compatible devices, we recommend that you always perform a test in advance. In addition, when performing a communication test, do not only check the connection, but also make sure that reading and writing to the expected addresses work correctly (because the operation of read and write commands may differ depending on the model).
Number of digits in the address
This driver allows you to specify 5 or 6 digits in the Modbus/TCP address settings. The driver you select depends on the number of digits, so please select the driver that matches your specifications.
