www.infoplc.netST programs allow named variables to be defined. This is similar to the use of symbols when programming in ladder logic. When selecting variable names they must begin with a letter, but after that they can include combinations of letters, numbers, and some symbols such as ’_’. Variable names

LADDER LOGIC - Sharif
ee.sharif.eduFrom the switches to the coil of CR1, the logical function is that of a NAND gate. CR1's normally-closed contact provides one final inversion to turn the NAND function into an AND function. • REVIEW: • Parallel contacts are logically equivalent to an OR gate. • Series contacts are logically equivalent to an AND gate.
