PLC conduction delay timer instruction (TON)
When the limit switch 1 is set, the indicator 2 ON 180ms (timer clocked). When the accumulated value of the timer 1 (.ACC) reaches 180, 2 lights off, the indicator 3 is turned on, and remains on until the TON instruction is disabled. If you disconnect the timer is timing the limit switch 1, then … Continue reading PLC conduction delay timer instruction (TON)
S7-200 addressing method in PLC programming
In the S7-200 series, addressing modes are divided into two kinds: direct addressing, and indirection. Direct addressing mode is used directly in the instruction memory or registers the component name and address number, direct to find the data. Indirect addressing is the address pointer is used to access data in the memory, before use, … Continue reading S7-200 addressing method in PLC programming
