I didn't learn the language well at first and now I'm very confused about data types! For example, I can't tell the difference between DINT REAL DWORD and floating point types. When are they used? What are their value ranges? Please give me some advice! This post was last edited by wopale3 on 2009-4-15 19:50 ]
1. DINT type data - 32-bit integer with sign bit, defined as "double integer" or "long integer", its representation method and range are: -2147483648~+L2147483647 2. The range of real is 10^38 +1 to 10^38 - 1 3. Dword is a double word. The first d means double. Double word is a single word. Double is a double word. Just look for a C language. Tan Haoqiang’s C language is very classic.
You are talking about the definition of some data in PLC.
Yes, these are some of the data types I saw when I was working on 300! Not very clear yet
