This article will discuss the use of various types of timer instructions in the Omron PLC<\/strong>. A timer is an instruction used to delay or control the execution time of an operation in a program. The timer operates based on a predefined duration (preset time). The CX-Programmer software<\/a> includes four commonly used timer instructions: TIM, TIMX, TTIM, and TTIMX<\/strong>. To test their use, in this program, each timer instruction will be applied to turn ON a lamp with a specific preset time.<\/p>\n\n\n\n

Program Objective<\/h2>\n\n\n\n
\"PLC<\/figure>\n\n\n\n

1. TIM Instruction<\/h3>\n\n\n\n

The TIM<\/strong> instruction is a countdown-type timer with a maximum preset time range of 0\u20139999.<\/p>\n\n\n\n

    \n
  1. This instruction counts time in BCD (Binary Coded Decimal)<\/strong> format, so the preset time parameter must be written with the “#”<\/strong> prefix.<\/li>\n\n\n\n
  2. The TIM instruction<\/a> has only one input parameter to activate the instruction and will turn Off if it does not receive a trigger signal.<\/li>\n\n\n\n
  3. TIM operates with a time interval of 0.1 seconds (100 ms)<\/strong> and does not retain historical time data.<\/li>\n\n\n\n
  4. \u00a0In this program, the timer’s preset time is set to 10 seconds<\/strong> by writing #100<\/strong>, and it will turn On Lamp 1<\/strong>.<\/li>\n<\/ol>\n\n\n\n

    2. TIMX(550) Instruction<\/h3>\n\n\n\n

    The TIMX(550)<\/strong> instruction is a countdown-type timer with a maximum preset time of 0\u201365535<\/strong> in decimal format or #0000\u2013#FFFF<\/strong> in hexadecimal format.<\/p>\n\n\n\n

      \n
    1. The preset time<\/a> must begin with an “&”<\/strong> if written in decimal format or with a “#”<\/strong> if written in hexadecimal.<\/li>\n\n\n\n
    2. The TIMX instruction has only one input parameter to activate the instruction and will turn Off without a trigger signal.<\/li>\n\n\n\n
    3. TIMX has a time interval of 0.1 seconds (100 ms)<\/strong> and cannot store time history.<\/li>\n\n\n\n
    4. In this program, the timer is set to 10 seconds<\/strong> using the value &100, and it will turn on Lamp 2<\/strong>.<\/li>\n<\/ol>\n\n\n\n

      3. TTIM(087) Instruction<\/h3>\n\n\n\n

      The TTIM(087)<\/strong> instruction is a count-up timer, also known as a Totalizing Timer<\/strong>, with a maximum preset time of 0\u20139999<\/strong>.<\/p>\n\n\n\n

        \n
      1. This instruction also uses BCD (Binary Coded Decimal)<\/strong> format, requiring the preset time to be written with the “#”<\/strong> prefix.<\/li>\n\n\n\n
      2. TTIM(087) has two input parameters: one to activate the instruction<\/a> and one to reset the stored timer history.<\/li>\n\n\n\n
      3. TTIM(087) operates with a 0.1 second (100 ms)<\/strong> interval and can save time history.<\/li>\n\n\n\n
      4. In this program, the preset time is set to 10 seconds<\/strong> using #100, and it will turn On Lamp 3<\/strong>.<\/li>\n<\/ol>\n\n\n\n

        4. TTIMX(555) Instruction<\/h3>\n\n\n\n

        The TTIMX(555)<\/strong> instruction is a count-up timer, also known as a Totalizing Timer<\/strong>, with a maximum preset time of 0\u201365535<\/strong> in decimal or #0000\u2013#FFFF<\/strong> in hexadecimal.<\/p>\n\n\n\n

          \n
        1. The preset value must be prefixed with “&”<\/strong> for decimal or “#”<\/strong> for hexadecimal format.<\/li>\n\n\n\n
        2. TTIMX(555) includes two input parameters: one to activate the instruction and one to reset the timer’s<\/a> stored history.<\/li>\n\n\n\n
        3. This timer operates at 0.1 second (100 ms)<\/strong> intervals and can save time history.<\/li>\n\n\n\n
        4. In this program, the timer is set to 15 seconds<\/strong> using &150, and it will turn On Lamp 4<\/strong>.<\/li>\n<\/ol>\n\n\n\n
