What is bit level addressing?
Re: bit level addressing The Modbus and EthernetIPforCLX support bit level addressing on words by adding a period followed by bit number. For example in Modbus, you can use 40001.0 to control a BasicIndicator color. The Modbus bit level is read only, which means you cannot change the bits with things like buttons.
