  1. Thank you for the answer. could you do a example in visilogic ?. I don´t understand you idea completely. Regards.
  2. Hello. I have two situations: One: I am working with the Module EXF-RC15, PLC SAMBA and stepper motor. The communication is ok, but I have a problem in the PTO configuration. In the PTO Move, when I start the move (MB100 from PLC samba), I get a number one in MI107 STATUS PTO. I saw the information and it said that a number one means "1 - Configuration data is invalid". I reviewed and followed the example C:Program Files (x86)UnitronicsUnitronics VisiLogic_CExamplesVersion 900Project examplesCommunicationsEXF-RC15, but I don´t find the problem in my program. Please I need your help. I attach an image and the program of the module EXF-RC15. Two: I need that the movement of the motor stepper with PTO MOVE to be done every time that an HSC counts 4 pulses from an encoder. The encoder has 400 ppr and it is in a motor 3 phases ,1800 rpm. what is the correct process for this application? do I need an interruption for this application or not? If I need an interrution, do you have some example? This application is for a transformer rewinder. Regards. Módulo EXF-RC15 V5.vlp
  3. Hello. I am working with a PLC Samba SM70-J-RA22, Remote I/O Adapter EX-RC1 and I/O Module IO-D16A3-TO16. I have a problem. I am using the HSO and the HSC of IO-D16A3-TO16 for stepper control. The HSO is connected to the HSC, so I read the number of pulses. I have different target of pulses, but I can´t get the target that I need. For example, If I need a target of 15 pulses, I get 18, 30 or 100. The target is near when I use a low velocity (15, 17 or 18), but in my application I use a high velocity. Therefore the motor stepper moves different pulses's number. In the HSO of the I/O Module IO-D16A3-TO16,only I have two parameter: output frequency and duty cycle. Also, I work with virtual HSC. I attach some images of the program. For information: MI21: Frequency HSO. MI7 :Set Target. MI11: Virtual HSC. MI12: Pulses´s number each cycle. Please I need your help. Regards.
  4. Hello. I want to communicate for rs-485 a plc unitonics m91 and danfoos fc51. I need to run, stop and change the frecuency for rs-485. I need help. Thank you
