1. BOOL, such as the IR area of OMRON, is the concept of bit. It only has two states, 0 or 1, which is actually equivalent to the digital input signal. It can be connected to the on-site digital value for logic processing.
2. WORD is a word. A word has 16 bits. For example, if you use the OMRON-C200HE host, enter 00200 ~ 00215 for a total of 16 digital bits (16 digital inputs). They can be combined to form a word. This word is binary data containing 16 bits. This is usually used for data calculations.
3. CHANEL is a channel, which specifically refers to I / O (input / output) channels. This channel can be a switch or an analog.
OMRON’s AD003 analog input needs to occupy a certain DM data area (for defining filtering, input channel is valid, etc.) at the same time, and the CPU reads the mold-in data through the bus backplane. (Word) Four-digit hexadecimal number, 0 ~ 0FA0, is also a 16-bit binary number. It is often used in analog data collection. You can see chanel in the symbol column of CX-P programming software.
4, UDINT also refers to the data type, not a signal, INT is an integer data, UDINT is a 32-bit 0 ~ 4294967295 integer.
