Why is the bit or coil level data incorrect? |
Article Number: 56 | Rating: 1/5 from 1 votes | Last Updated: Wed, Feb 25, 2015 at 3:24 PM |
Bit read and write commands are issuing properly, and responses are coming from the slave(s), but the data is not correct. When setting the intaddress field for a bit or coil Modbus command (Modbus function codes 1, 5, and 15), the internal address specified in the command must be at the bit level.
