Question

Instructions:

be programmed directly using RSLogix. You must create a new program file for each problem and setup the proper controller type. Identify each problem with a program file using the following format: E3_x_FML.RSS. Where x is the problem number and FML are your first, middle, and last name initials. Enter the ladder logic on the corresponding window. All symbols must be specified and a description must be added stating the type of device with its normal state (NO, NC). Upload the three (3) .RSS files and submit them through

Design a PLC ladder logic program to control the operation of an alarm system using the following sequence:

- An ALARM must be energized and stay energized (latched) when a limit SWITCH is activated once or when a motion SENSOR is activated three (3) times within a space of 30 seconds.

- The ALARM can only be de-energized (unlatched) by pushing a hidden normally-open momentary-contact BUTTON.

- Hint: latch the timer with a sensor activation and use a count-up instruction to count the number of sensor activations. Reset the count and unlatch the timer if the timer is done.

- Program SWITCH, SENSOR, and BUTTON using bits 0, 1, and 2 of the input module respectively.

- Program ALARM using bit 0 of the output module.
