  1. How to Detect Pulse Presence? Pulse Catch?

    Thank you very much. It works just fine 
  2. How to Detect Pulse Presence? Pulse Catch?

    Anyone? I still couldn't figure out, nor the technical support.
  3. Hi all! I need help with detecting the presence of a pulse signal on an input. I have a İQ-F FX5U PLC, and a sensor generating a pulse signal with 500 Hz frequency. When the sensor detects nothing, it outputs just flat 0 volts. But if it detects something, it outputs a 500 Hz pulse signal with a varying duty cycle (the duty cycle depends on the condition of detection but that is not relevant, I don't need that). I only need to detect whether there is a pulse signal on the input or there is just nothing. I thought of using Pulse Catch Function which I've never used before, but I couldn't comprehend how it exactly works. Looking at the image below; since there will be always a pulse signal on the input when the sensor detects something, "Input Device" will always be ON. And when the sensor detects nothing, there will be no pulse signal on the input, so the "Input Device" will be OFF. But what is that Input Device exactly? Is it a relay? An output? Or is it the result of an instruction (which I've found nothing as such)? So, if anyone can help me with this Pulse Catch Function or another solution, I would be glad.
  4. Hi all! I'm trying to read data from a magnetic sensor of Roboteq's called MGSW1600. The sensor allows Modbus ASCII communication with RS232 interface. I'm already using a RS232-RS485 converter but that's not enough to communicate. In attachments, you can find the related settings of the sensor for communication and packet structure for sending and receiving data. I've tried using non-procedural communication and did all the settings but I guess sumcheck here is CRC, not LRC as denoted in the sensor's datasheet, moreover, I couldn't figure out how to sent all the necessary information to the sensor (node address, function code, register address to read from, number of registers to read) using RS2 function block. So, I'm thinking of using Predefined Protocol Support Function as soon as I obtain the necessary devices I ordered online. I also added Predefined Protocol Support Function settings in the attachments. I need help with the ladder program and confirmation of settings or any other idea about how I can establish communication between FX5U's built-in Modbus RTU RS485 port and Modbus  ASCII RS232 sensor.
