  1. Hi; In addition to the above, you will also have to set up the Analog Inputs and Outputs in the IO-Ai4-AO2 Modules. These are not automaticaly transfered when changing PLC types. Note the setup in the Old systems, redo in the new. DanT
  2. Hi; The V350-35-T2 has 1 Com Port and a USB port for programming. -- They both share the Same port - Port 1. Programming, Online Monitoring and RS485 Modbus through this port will be a challenge for troubleshooting and programming. I will recommend using a 2nd Com Port for the RS485 communications -- V100-17-RS4X ( isolated RS485) Then you will be able to go online and monitor the communications with the drives thru the programming port - Com 1. The cost of the module will pay for itself in reducing time and effort. DanT
  3. Hi ; What is the PLC Model? Do you know what version of VisiLogic was used to program the PLC? Older Versions are still available for download and use. If you do not know what version was used. Get the OS Information from Info Mode, or Connection - Get OPLC Information Ask Support@Unitroncisplc.com what Version of VisiLogic was probably used. - obtain it and install it. Modify the program ( Original that you worked from -- NOT the new one you just did - will not be compatible) DanT
  4. Hi; The EX-RC1 is a Vision Product. Download VisiLogic. Use VisiLogic to communicate with the EX-RC1 via the Serial Poert ( 57,600 K ) ( RS232-CB1 COM Cable) The EX-RC1 is based around a stripped down V120 , set up for CANBUS communications. You can upload the configuration, save it and download to the new one. Remember to set the DIP Switches for the address. Check the configuration after you download and the structs for the data transfers. DanT
  5. Hi; Go Online with the PLC and look at SI 9 LCD Backlight Intensity -- adjust and see if this helps. If there is vibration, maybe open the unit and check the connections of the Sreen to the Main Board Possible the data from the display chip is not getting to the display.
  6. Hi; Can you communicate with the PLC via the USB Port? ( Get OPLC info ) Is there a program in the PLC? What is the start up screen? Are you calling this screen in the program and do not have a return ( exit) set up? DanT
  7. Hi; U90 ladder is the program to use with all M90/91 PLC's and JAZZ Series You can upload the program from the PLC If the Prpgram is password protected, you enter the password. Start by making sure you can communicate with the PLC using the RS232-CB1 Com Cable + a USB to Serial Adapter if necessary. Default Baud rate is 9600 Controller M90 OPLC Settings Get Version -- This will retrun info about the PLC you are connected ( else you get a Com Error message) If Successfull, Now Controller Upload -- to get the program into your computer. -- Save it right away before trying to modify the program. DanT
  8. Hi; As pointed out above, Data Collection is possible using the Data Tables you can create. Note the following: V120 Series is an older series. NO Ethernet Option, NO Micro SD Card Slot Getting the data out of the V120 will have to be done via the RS232/RS485 Com Port - Serial. Upgrade V130-J-TR2 -- Ethernet Option (V100-17-ET2) , Micro SD Card Slot, ability to use the SD Card Utility program. or any other Vision Enchanced Mode OPLC l(V350, V430, etc) SAMBA Series can be used if the data is limited and the program not complex - SAMBA has Severe memory imits, and No Micro SD Card Slot, but Ethernet (V100-17-ET2) is an option. SAMBA has No Options for additional I/O. ( Remote I/O can be considered, but at the expense of the limited internal memory you will be left with to use) DanT
  9. Hi; I see the note about MB 0 being set by SB2, Are these nets in a subroute? Is the subroutine being called? If not sure - put a Incremental counter ( XI whatever) at the top of the subroutine- attached to the rail. If it counts, the routine is /was active. If not counting, subroutine ius not currently being called. DanT
  10. Hi Surg; Are the Tablet ( wireless) and the USC PLC on the same network? The VNC should be direct connection. Another option is a P C with Monitor or a Laptop on the same network - VNC will be a direct connection. If the Tablet and USC are on different networks, then you have to to go thru the customer IT to get it set up. Yes, UniCloud is another Option - you can use a Starter Subscription - and also have some data in the Cloud. DanT
  11. Hi; In Vision PLC ( V350 to V1210 ) use Info Mode You can change the date and time from there There are 2 methods : at Info Mode Menu, Date and Time, or Operands Si 31 ( Hours/Minutes ) DanT
  12. Hi; Math required for scaling. In Hardware config, choose an analog Input on the V200-18-E4/4XB 0-10V Input ( there is no 0-5 V ) Select an MI to Store the raw value. In the ladder us the Linearize function Scale the Analog Output based on 0-10 V Input X Axis 0 to 16384 ( 14 Bit Analog Input -- 0 -1 0 V ) Y Axis 0 to 222 ( 0-100 PSI 100/45 x 100 ) If you want 0.1 PSI Resolution 2220 Test from there DanT
  13. Hi; I reviewed the program. You are not properly triggering the Modbus Read The Tag TAGASITEMP is set up as both the data Tag and the Trigger -- will not work. Change the trigger name to ( say) TAGASITEMP-TRIGGER in the Active Periodic loaction then in the ladder turn that Bit ON to read the coil data each time you want to read the coil. DanT
  14. Hi Rapsept; What version of UniLogic are you using? DanT
  15. Hi Ask Support if they have this information available.. DanT
  16. Hi; In the Unitroncis Vision PLC, all the MB's (Memory Bits) and MI's ( Memory integers ) used are accessable by Modbus Reads and Writes. MB's are Modbus Coils MB3150 is Modbus Coil 3160 MI's are Modbus Registers MI 100 is Modbus Register 100 For efficiency of Modbus Reads and Writes, the programmer will probably lump MB's and MI's in groups that they know will be Sent or Read by Modbus commands. Getting the Com Parameters Ask the supplier of the PLC. OR The way of checking for the Com Parameters is via the Info Mode. On a touch screen PLC, press an area of the screen not activly used for touch for about 6-9 seconds. Enter Info Mode -- Password 1111 Choose Serial or Ethernet and explore. DanT
  17. Hi; What PLC are you going to use it with ? JAZZ or SAMBA Series -- NO, they are not expandable Vision Series -- OK -- And you need the EX-A2X as Alex has pointed out. UniStream Series -- These will need an EX-RC1 and a CANBUS Adapter Module. There are UniStream Equivalents if it is for UniStream Series. -- Let us know the Model PLC so we can recommend the proper adapter cable DanT
  18. Had to answer this : Well I Cracked the egg to get out. My Feed was on the other side. What are You Sweating about? Dant
  19. Hi; The Cable used in the older EX-A1 is custom made, pinout is different from a standard Ethernet Cable. The EX-A1 has been replaced with the EX-A2X and this uses a different cable - again custom - and is polarized ( PLC end and EX-A2X end ) Standard Ethernet Cables will not work on these. DanT
  20. Hi; Since UniLogic will not support anything Python, here are 2 possible methods: UniLogic Supports Modbus Protocol You can get Modbus Libraries for Python Unitronics has a feature called Message Composer -- you can create text based messaged with variables Create messages in Python and in UniLogic to exchange data. Get the UniLogic Example Programs Zip file. Under Communications - Protocol there are some example to give you ideas. DanT
  21. Hi; You probably solved the issue by now, but ( and for others ) : In VisiLogic, : Open Connection and Get OPLC Information ( Make sure you are communication with the PLC ) When that answers back correctly, Click on the Middle ICON in the Communication - PC Settings Box -- Yellow Sun with Red Dot Install Operating System Click on Check and follow the prompts, The process may decide to install just 1 file, of maybe all 4 files. Just click and let it do it's work -- takes several minutes. There is a progress bas that shows what is happening When done, it lets you know, Then reset and download your program. DanT
  22. Hi; Have you reviewed how VisiLogic Handles Modbus register addressing? MODBUS Help is hard to Find in Help, but start here: ( there is a lot of info there- just well hidden ) Help, Index, MODBUS Find and look at Slave Addressing. Notice the SAMBA ( Vision Color) addressing is set up in HEX ( Base 16) Know how to convert Decimal to Hex and back -- Unitronics will do it automatic , but beware ! in the example illustrated 7028 is Hex 0x7028 = 28712 decimal So is 8320 Decimal or Hex? 8320 Decimal = 0x2080 ( H-2080) 0x8320 Hex = -31968 decimal ( MI's are Integers +/- 32767) Just something to consider DanT
  23. Hi Are the other 2 PLC's Unitronics PLC's ? If they are connected by RS 485, the use Modbus to collect the data Each PLC must have a Unique Address 1 2 3 etc. If they are connected by Ethernet, use Modbus TCP Check Help - Examples, Projects - Communications for example programs on how to do this. If they are not Unitronics PLC's, do they support Modbus Protocol? If they are connected by RS 485, the use Modbus to collect the data. Each PLC must have a Unique Address 1 2 3 etc. If they are connected by Ethernet, use Modbus TCP Once the connections are made, you get the data from the PLC's and store the data in the V700 ( MI's) and then display the data on the screen. DanT
  24. Hi; Where are you using these coils as coils else where in your program? If you use a coil as a coil say 3 times in a program, only the last state of the coil is valid at the end of the program scan. Remember a PLC Scan starts at the top and ends at the bottom. Coils MB 312,313,314 and 317 must have other factors controlling them. Can you post a copy of your program. DanT
  25. Moderator : Post to a better location - Hi; What PLC are you using? How are you communicating with the Flow Meters? DanT
