David, That question can get complicated very quickly. [LINK1] [LINK2] But I will try to simplify it for you from the viewpoint of a programmer. A digital input / output is a 0 (false) or 1 (true) for the PLC program. Then an analog signal (input / output) is a range of numbers. In the LOGO PLC as an example the 0..10V analog is seen inside the PLC program as a number between 0 and 1000. That means 1.23V will be represented by the number 123 for the program running inside the LOGO PLC. Other PLCs have other number ranges that represent this variable analog signal. So it is important to know the hardware you are using and know what resources in software is available to process the value that you get / create. Was this the answer you were looking for? Please be more specific for a less than general answer. Greetings. w |
