  1. Stepper Motor Control with FM353?

    Mr. Electrician, Using FM353 requires using another S7-300 CPU and writing codes for communication between two CPU via Profibus. You can use Remote I/O with the existing Profibus. You need: 1) ET200S Interface Module IM 151-1 (6ES7151-1AA04-0AB0) 2) Power Supply 3) 1STEP 5V/204kHz Module (6ES7138-4DC00-0AB0) ET200S is small Remote I/O units which can be mounted in small cabinet close to the machine.

  2. Programming plc through profibus

    Paul, You need mpi cable which has male connectors on both sides. Regards, Behnam www.sigmaprocess.ca
  3. Programming plc through profibus

    Paul, You can use the PG port on the profibus connector on the ET200S, if there is any. If not, you can either replace it with one or use a linger MPI cable to reach the main cpu. Regards, Behnam www.sigmaproess.ca/blog
  4. Programming plc through profibus

    Paul In this case, You need to monitor the plc inputs. For monitoring plc inputs: 1. You create a VAT table 2. Add your inputs to the table 3. Monitor the inputs Regards, Behnam www.sigmaprocess.ca/blog
  5. Replacing a TP170A HMI with a TP177A HMI

    Grinbo, While transferring the file to HMI, there is an option called "Back Transfer" which allows you to upload the file from HMI. Programmers usually don't do that because it needs lots of memory on the HMI. You can try but i doubt you have any luck with that. You have to contact the machine manufacturer or whoever did the programming for the machine and get the original HMI code from them. Regards, Behnam www.sigmaprocess.ca/blog
  6. Programming plc through profibus

    Paul, Your ET200S is part of a system which is hooked up to another plc as Master. Let me know why you want to go online with the system? Regards, Behnam www.sigmaprocess.ca
  7. Programming plc through profibus

    Paul Could you please tell me exactly what you have and what you want to do? Regards, Behnam www.sigmaprocess.ca
  8. Programming plc through profibus

    Paul, You need: 1. Step7 software 2. MPI or Profibus cable 3. Siemens PG or CP5512 if you have a laptop or a CP Card if you are using a PC Regards, Behnam www.sigmaprocess.ca
  9. Programming plc through profibus

    Paul, It is absolutely possible. Regards, Behnam www.sigmaprocess.ca/blog
  10. Replacing a TP170A HMI with a TP177A HMI

    Grinbo, Take a look at the attached file for migrating the file. TP170A and TP177 are identical based on the screen resolution and active screen area. You need the original hmi file, then you can ask anybody to download it to new HMI. Regards, Behnam www.sigmaprocess.ca/blog TP170A Migration.pdf
  11. Replacing a TP170A HMI with a TP177A HMI

    Grinbo, Do you have the oiginal code for hmi? Regards, Behnam www.sigmaprocess.ca/blog
  12. Help - major Virus issue

    Grrett, 1) If the programmer hasn't asved the projects in another folder you can find it in Siemens default folder: C:\Program Files\Siemens\Step7\S7Proj 2) Check if you can run Automation License Manager under either Siemens Automation or SIMATIC from Windows\Start\All Programs If you can't retrieve them but you have a proof that it is bought from Siemens, You can cotact Siemens to get a new license. Regards, Behnam www.sigmaprocess.ca/blog
  13. OB40 HW interupt on S7300

    Danny, You need an input card which has Hardware Interrupt opton on it. Digital input module SM 321; DI 16 x DC 24 V; with Hardware and Diagnostic Interrupts, clocked; (6ES7321-7BH01-0AB0) Regards, Behnam CPU315 <-> S120, How?????
  14. profibus

    Bee, The CPU will keep polling and checking on the lost slave but it generates System Fault which causes the rest of the slaves to turn off their output till the issue is solved. Regards, Behnam www.sigmaprocess.ca
  15. profibus

    Hey Bee, Losing a slave on profibus will mess up the bus and will cause error. In a plc system you are not suppose to lose any slave because that will cause problem to your process too. In your case, if that slave is not important and it has to be turned off you can use a RS485 repeater. You will have rest of the line on one side of the repeater and that specific plc on the other side and this won't mess up your bus. Regards, Behnam www.sigmaprocess.ca
