The IEC 61131 standart offers a definition of Timers. PLC3000 integrates only TON timers that can be set by defining the time base %Ti.TB, and the preset value %Ti.PV. The timer is triggered by activating the input %Ti.IN, and the output %Ti.Q goes to 1 when the current timer value reaches the preset value. The […]

Mnemonics in the LD Language
At each variable can be associated a mnemonic. It is then possible touse the mnemonic or variable completely transparently in programs. To associate the variable Switch to the input %I0, the variables RedLight and GreenLight to the outputs %Q0 and %Q1 respectively, it is possible to specify them during the variable declaration in the Ladder […]
Counter LD
The IEC 61131 standard offers a definition of Counters. PLC3000 integrates up and down Counters. It is necessary to define a preset value %Ci.PV, which can be set with an integer value. The current value of a counter is set to 0 when %Ci.R is activated. The current value of a counter is set to […]
Edge Generation – ST
PLC3000 does not include Rising and Falling Edge functions. However, they can easily be generated from the available memory bits Generation in ST Generate a Rising Edge on %I0 is done by considering a memory bit, e.g. %M1, such as <img width=”300″ height=”130″ src=”https://plc3000.com/wp-content/uploads/2021/05/FrontMontant-300×130.jpg” alt=”” loading=”lazy” srcset=”https://i1.wp.com/plc3000.com/wp-content/uploads/2021/05/FrontMontant.jpg?resize=300%2C130&ssl=1 300w, https://i1.wp.com/plc3000.com/wp-content/uploads/2021/05/FrontMontant.jpg?w=533&ssl=1 533w” sizes=”(max-width: 300px) 100vw, 300px” /> […]
Counter – IL
The IEC 61131 standard offers a definition of Counters. PLC3000 integrates up and down Counters. It is necessary to define a preselection value %Ci.PV, which can be set with an integer value. The current value of a counter is set to 0 when %Ci.R is activated. The current value of a counter is set to […]
