ModBus TCP and Siemens 1200
« on: March 17, 2014, 03:58:13 AM »
Hello, I have an application with Siemens 1200 using ModbusTCP. It works fine but I don't understand How I can access at only one bit. I'm able only to access a word (i.e. adress 40001) and if I want access to a bit I can analize bit to bit of a word. Any suggestion?
There is also a possibility to access floating poit variable? thank you
