  1. Using this https://vi.aliexpress.com/item/1005003091082827.html?spm=a2g0o.productlist.main.7.12f6nnNTnnNTgu&algo_pvid=6ea240c0-c56c-4f95-88b1-37e5953486df&aem_p4p_detail=202401100407583607811113199410007751814&algo_exp_id=6ea240c0-c56c-4f95-88b1-37e5953486df-3&pdp_npi=4%40dis!EUR!0.49!0.42!!!0.52!!%402101fb1a17048884783171605ee0d9!12000024024728654!sea!SI!111006486!&curPageLogUid=jQJKfO8xxbPs&utparam-url=scene%3Asearch|query_from%3A&search_p4p_id=202401100407583607811113199410007751814_4 but than you need to make this http://pencho.my.contact.bg/start/comp/rs232/unitronics-rj11.htm You can also buy it from Unitronics.
  2. Putting PID stus messages on screen is a good idea. Autotuning did help but than situation repeated again so I installed new SAMBA with modified program to reset Integral error in case of windup or winddown (even if I do not know if it ever occured).I also display pid status. Now Im waiting for next call from client.
  3. Yes , also encounterd the same in my app with SAMBA. For weeks it worked just great and then at some point output of the PID went 100% ad only autotune get rid off it. I did not check the PID status since I was not on site ,but costumer lost confidence in unitronics SAMBA. It is strange because it worked perfect for some time. Instalation is on wery remote site and I can not get all information in time (hidroelectric power generator). If windup would occour , should i get this symptome?
  4. It will work , but Im sure you will have some hard times . We are here to help if needed.

  6. Instal ethernet (LAN) card V100-ET2 from unitronics into your PLC and buy one of this: https://www.aliexpress.com/item/1005003676953168.html?spm=a2g0o.productlist.main.13.6cc7m3pcm3pc3Z&algo_pvid=da738608-6535-4114-b3d5-ddef7a5cb6c3&aem_p4p_detail=202305130045542171265101056280006842707&algo_exp_id=da738608-6535-4114-b3d5-ddef7a5cb6c3-6&pdp_npi=3%40dis!EUR!71.26!61.28!!!!!%40212244c416839639543775227d073c!12000026759305831!sea!SI!111006486&curPageLogUid=XOQHhc15r2vw&ad_pvid=202305130045542171265101056280006842707_7&ad_pvid=202305130045542171265101056280006842707_7 I done it before and it works.
  7. And arduino as I know operate on TTL signals logica l"1" is +5 0r 3V, logical"0"is 0V. Serial ports on samba are real RS232 signals (+-10V) where logical "1" is -10V and logical "0" is +10V.
  8. I think this is about analog OUTPUT , and it is corect .
  9. With a help of Daags instructions (I do not know where did he found them) I manage to get my samba 70 touchscreen work again. Before i did not manage to enter calibration mode since " x value" was always 799, only y changed correctly. Once in the calibration mode I simply touched little squares and voila it works. It seems that in eeprom which stores calibration values some glitches caused corruption.
  10. Maybe ......... I assume that you are using interrupt routine , right?
  11. Thank you Zoran. Im also doing something with ethernet and it works fine, but ocasionaly connection drops and I need to reset my V570 to restore. "Inače" Im from Ljubljana- Slovenija. Salute to my "ex" brothers in Serbia. 😀😀
  12. Can you tell where did you find "keep alive" and "keep master connection"please? Thank you Ps : are you from former YU m,aybe?
  13. What about Radio modem?How far is the remote object? Is there eye sight beetween?
  14. Also , are yours termocouples connected directly to the inputs of PLC or there are some extension cables between? There should be no other joints except on the PLC input.
