  1. Weekly Timer

    If you would like to trigger something at the same time, same day every week, compare the system registers with a time and day you set. Are you using a FX system or Q ? For FX systems: D8013 = Seconds D8014 = Minutes D8015 = Hours D8019 = Weekday (0-6)  
  2. Resistance Testing

    Don't know if I really understand what you are looking for here. What are you planning to use, a PLC, microcontroller or some passive components ? A very easy way to detect that low resistance (with a PLC) is to connect a 500 ohm resistor to the 13,4V supply, and the other end of the 500 ohm resistor will be your positive test point, the negative test point is then ground. With 30 ohm connected to the test point, you will have 0,758 V at the test point. With 35 ohm, 0,876 V. 0,4 ohm is roughly zero Volt, and no (test) resistor connected is 13,4 Volt. Easy to detect with an analog input. You could also a PT100 input, 30 to 35 ohm would give you a reading of roughly -160 to -170°C.
  3. How can I do a simple sequence step delay

    Welcome to the limited world of Siemens The output from a timer function allows only a boolean bit on the output.  
  4. How to unblokc the protected block in S7-1500 IN TIA

    The block can only be compiled with a valid password as far as I know
  5. sockets FX3U-ENET P502

    You can use it with MC protocol and Modbus TCP (at the same time), and yes, you have to load the Modbus library.  
  6. sockets FX3U-ENET P502

    One Modbus TCP communication occupies 2 channels The P502 is a FX3U-ENET with port 502 opened
  7. password hima

    The HIMA PLC is a safety PLC if I'm not mistaken. I doubt you can erase or replace the program in it without the password.
  8. FX5U With E-terminal

    Did you monitor the status of any PLC inputs or outputs in the E-1000 display ? I noticed that one has to use hex addressing in the display, not the octal used on the PLC. X12 in the PLC is X0C in the E-1000 panel. Took a while to find
  9. Let's check if I understand your setup Your shunt will give you 75mV at maximum current flow. Then you have a transducer that will give you 7,5 V at the 0-10V ADC input. What resolution have you set at the ADC, 4000, 10000 or 16000 as max converted input value ? Could you please supply a drawing how it's connected ?
  10. First of all, how do you measure the current ? Are you detecting the voltage drop over a fixed resistor and calculate the current from resistor value and voltage drop ?  
  11. TIA Portal V13- Alarm for Bool Data type

    Pack all your alarms into a word. As an example: AlarmWord MW300, This will be the word you look at in the panel. Then move all your BOOL tags into the word. Alarm1 M300.0 Alarm2 M300.1 And so on. Keep in mind that when you shall detect "Alarm1" in the panel, you must look at MW300 bit 8. "Alarm2" will then be MW300 bit 9.
  12. Tia Portal V14 Real time graph

    I'm not sure, but it might be possible to use the "f(x) trend view".  
  13. Tia Portal V14 Real time graph

    I would use the PLC memory to store your samples since you want a resolution ten times better than the update rate between the panel and PLC. Use a time delayed interrupt to store your samples.
  14. S7-1500 FW v 2 / Profinet issues non-Siemens devices

    I had an issue that's new for V14 when I was a slave partner to a SCADA system. In V14 you have to "Permit access with PUT/GET communication from remote partner". You'll find it in the HW config if you have the similar problem. General > Protection & Sequrity > Connection mechanisms.   
  15. ModbusComm

    Decrease the number of outputs you read, or do you really have over 100 outputs ? Try with the first 16 ones and see how it goes. Else, see if you can read them as a register (Y0-Y7 + Y10-Y17) using function code 0x04 and address 0xA7A8. Do keep in mind that the address asked for might be offset by 1.
