  1. MJ10-22-CS10 designed to provide power to PRJ adapter from PC COM port. More important is to use proper connection of Rx and Tx wires. *Used by Unitronics phone cables are crimped as cross. Following document include CS10 adapter pinout: http://media.klinkmann.fi/catalogue/en/Unitronics/Unitronics_Manuals_Jazz_Port_Install_en_0511.pdf
  2. I used 3x560 ohm resistors in parallel. This equivalent to ~187 ohm. Resistors connected between +24 V and contacts 1 & 6 of PRG adapter. *Wires 1 & 6 cut in the middle of cable. Wires 2 and 5 connected to 0V of PLC. *I used 6 wires phone cable (cross-crimped) and open it in the middle. Opposite to PLC cable end connected to MJ10-22-CS25 adapter, then to USB-to-Serial converter. Following is Get result from PLC Additional to this, I tested 560+560=1120 ohm resistor. Online (Debug) mode works. Please use 1.1 kohm 2W resistor and test communication. I hope it will work. *MJ10-22-CS25 adapter include inside 2 diodes, Zenner diode and electrolytic capacitor. Please post your results for feature readers.
  3. Need help to connect Unistream to ex-rc1

    Hi, You have to set EX-RC1 Unit ID by DIP switches. See next document: https://unitronicsplc.com/wp-content/uploads/2015/12/EX-RC1_SPEC_05-08.pdf I hope this helps.
  4. Hi Svjatoslavs, Resistor of 180 ohm with current 0.1 A dissipate 18.5 V* 0.1 A=1.85 W. You should use 2W resistor. So variable resistor should be powerful... B.R.
  5. Hi Svjatoslavs, Schematics seems to be right. What your test show? Is communication working? By the way, what Arduino MODBUS stack do you use?
  6. Hi Svjatoslavs, Please use next documents for PRG adapter: https://unitronicsplc.com/wp-content/uploads/2016/06/MJ20-PRG_TECH-SPEC_10-09.pdf https://unitronicsplc.com/wp-content/uploads/2016/06/JZ-PRG_INSTL-GUIDE_10-09.pdf Last one include CS10 adapter wiring. I will recommend to connect contacts 1 and 6 of a MJ20-PRG to contacts 6 and 1 ofh MJ10-22-CS10, connected to RS232 port of PC. Or connect contacts 1 and 6 of MJ20-PRG to +24 V by resistor (24-5.5)/0.1~=185 ohm. You have to use GND with Tx and Rx signals. Tell us how it works.
  7. file extensions

    Hi John, All these files are backups. Number after decimal point show backup data base version. For example, project last time stored in data base version 144. Now you open it in a newest VisiLogic, which use data base version 145. Previous project stored as .144. I recommend you zip all of them and keep in a safe place. You always can delete everything. But one time you may find your archive useful. You always will open such project by adding .vlp extension in proper, or on last VisiLogic version. B.R.
  8. Hi, MJ20-PRG module require external power on pins 1 & 6, and it use MJ20-CB200 and MJ10-22-CS10 for this. And it cannot use DTR and DSR signals. Use MJ20-RS module instead of MJ20-PRG. It require 4 wires cable from RS232-CB1 set. *This cable is crimped as "cross". 2-3-4-5 pins of one connector crimped to 5-4-3-2 pins of other connector. Everything should work.
  9. Maximum numbers of LEDs is 32: If you need horizontal bar - you have to extend bar graph and correct number of LEDs.
  10. Could I re-order SI250

    Hi, You can re-arrange keypad-entry variables. Use "Variables Tab Order" Change variables order as you need. Is this what you need?
  11. Download error

    Hi Nicola, What is a windows version you use? Connect USB cable to JZ20 PLC and check what is a driver name and version activated in Devices list. Post information. B.R.
  12. Jazz online error

    Hi Nicola, Please send your smallest code having this behavior to support@unitronics.com and explain step-by-step what you doing. This will help us to simulate this case. Add next information to your email: -JZ20 OS version (display snapshot). -U90Ladder version. -What communication interface do you use - USB, Ethernet, or RS (what is adapter model and driver version). -What is a PC OS (XP/7/8/10) and PC model? -Does this happens at this PC only, or at others PCs too. -Does this happens with other interfaces? We will answer you with results. B.R.
  13. Data Base in Samba

    Hi, There are many examples in VisiLogic installation directory: C:\Program Files (x86)\Unitronics\Unitronics VisiLogic_C\Examples\Version 900\Project examples\Data Table For example, V570_Data_ Log.vlp B.R.
  14. Hi, Can you provide more information about data base and API you wish to use?
  15. vincular un encoder a lader en visilogic

    Translation --------------- I have a V570-57-T20B screen with a V200-18-E1B module and I need to link an encoder to give measurements of length and I do not know how to create it in a lader to link it and show me on the screen the measurement and to be able to program several measurements would appreciate if Can someone help me with this project
