  1. Hi; Translated in system mode do not get to verify: boot and factory boot but toggle for factory initialization or communication cannot be established What happens after a Power OFF and then Back On? What screen appears? Can you communicate with the PLC then? DanT
  2. Hi; In the screen shot, F1 is a NO Contact. That means as long as F1 is Pressed, the shift will happen every scan cycle. So the data will be thru the shifting in say 16 cycles. - a blink of the eye. Try with a ---|P|---- for F1 and every time the F1 key is pressed, then 1 shift at a time - abd observe the output. Aslo, if it in a subroutine, be sure it is being called. and maybe note how you are calling the subroutine - every scan cycle or intermittent. As Joe noted, post the program so we can see the whole picture. DanT
  3. Hi; UAC-CX-01RS2 to the PLC USC-B5-TA30 -- Will NOT Work. UAC-CX-01RS2 is for use on the US5/US7/US10 Models. USC-B5-TA30 requires UAC-CB-01RS2 Com Module - it sits beside the USC CPU on the DIN Rail. Contact your distributor. DanT
  4. Hi; How are the sensors wired? 2 wire 3 wire or 4 wire set up? Any loose connections? Is the cabling shiended? Is the tip of the PT400 actually isolated from ground? Is the cabling kept away from high voltage and any VFD wiring( if present)? DanT
  5. HI; Based on the above, You will have to replace the PLC, They are not repairable. You will need a copy of the orginal program to load into the new PLC. Visilogic programming software is a Free Download from the Unitroncis website. You should also get the USB Programming cable - for SM43 or SM70 ( SM35 uses the RS232-CB1 Com Programming Cable) Is there and Ethernet Card or CANBUS Card, or Serial Com Card Installed? -- Replace them also - they may have gotten damaged also. Contact the Machine Builder, or Unitronics sales for the closest distributor. DanT
  6. Hi Mac; SM43-J-R20 or T20 has Fixed I/O is designed not to be expanded using standard IO-xxx Modules. The SAMBA Series in a subset of the Vision Series, meant for simple self contained projects. You will have to go upto a Full Vision Model. V430-J-R34 22 Inputs, 12 Relay Out EX-A2X Expansion Adapter IO-DI8-RO8 8 Inputs, 8 Relay Out ( EX-DI8-RO8 is an option -- Fixed I/O Expansion 8 In, 8 Relay Out ) You can also consider Kratmel's solution, but you have to re-adjust all the Canbus Struct Addressing to make it work. Another Method is using the remote I/O - SAMBA + Ethernet Module + URB-TCP2 + IO Modules. Again it is the programming overhead to make it work. These are for more experienced Unitroncis programmers who know the tricks from experience. SAMBA has limited Programming memory. DanT
  7. Hi; In INFO Mode there is a menu item for Ethernet. This provides informtion about the Ethernet Adress and Ports in use. You also need to know the name of the PLC - that is under Version - Software You need both the PLC Name and the IP Address to connect to the PLC via Ethernet. ( The PLC name acts like a password, and assues you are connecting to the right PLC ) DanT
  8. Hi; One issue can be mis-matched versions between UniLogic on your computer and the Version used to download the original program into the PLC. ( UniLogis is VERY Picky about this The versions MUST MATCH ) What version of UniLogic OS is in the PLC? UniApps -- About What version of UniLogic are you using ? If necessary you can download older versions of UniLogic and install them - Yes you have to uninstall the current version first. ( To have Multiple versions of UniLogic available on your computer, see the posts elsewhere in this forum) DanT
  9. Hi; When using the EX-RC1, you have to understand how the Data is transfered and the use of the Structs ( at BOTH Ends ) Modify the EX-RC1.vlp example to limit to the devices used. Order of the IO Modules should be IO-DI8-RO8, IO-DI8-RO8, IO-AI4-AO2 Review the EX-RC1 Analog Example and add the structs for the Analog AFTER the Digital Structs. It will take a bit of experimentation to get it right. Digital I/O is compressed into an Integer and sent and received, Analog is sent as Integers without any compression. The structs have to be the same at each end . DanT
  10. Hi; On UniStream, There is a method to change the maximum number of elements available on a HMI Screen. Contact Unitronics Support for the way to do it. DanT
  11. Hi; Contact Unitronics Support to help get this resolved. support@unitronics.com depending on your location, US Support or Factory support will answer and assist you. DanT
  12. Hi; If you have Subroutines linked to the Screens, then these will stop running when you change to another screen. Subroutines only run when called. ( Oline mode can fool you into thinking they are running beacuse of the Red Power Line. Add an INC MI or XI to the power rail in Net 1 and it will couunt when the subroutine is active) DanT
  13. Hi; The UniStream B3 Models - 2 Only -- are in the UniStream PLC Section - Tech Documenmts USC-B3-R20 or T20. They do not have a Built in HMI, The HMI is Virtual -- VNC from Display or PC The B3 is a subset of the Full UniStream Series and has Limits, but still very functional for the right applications. The unit has 3 GB for programming, Spec sheet does not specify a limit to the Virtual HMI's, or subtroutines called from the main. ( The layered limit is subroutines calling subroutines.) DanT
  14. Hi; Rest API is a functon in the UniStream Series only. V700 is a Vision Series PLC, older than the UniStream Series, and does not have/support the Rest API Function Vision Series is based on another OS technology - Microcontroller and Fixed Structure. You may have to resort to an intermediate solution - Raspberry PI( for example) to get the weather data, then Modbus the infomation into the V700 DanT
  15. Hi; VisiLogic has Function Blocks for sending and receiving data as you have described. FB Protocol > Protocol Scan ( to receive data from a device) and Protocol Send to send Data to a device For FB Protocol Scan setup, refer to an example in Help Examples : Help Examples Version 900 Projects Communications FB Protocol V130_Receive _4_Numbers There is also an example for FB Protocol Send ( to send data to another device) in the same examples folder. Post your code AND how you have the protocol Scan Setup done. We can review. DanT
  16. Hi; Your code does not show the setup for the Protocol Scan -- How the data is structured to receive For FB Protocol Scan setup, refer to an example in Help Examples : Help Examples Version 900 Projects Communications FB Protocol V130_Receive _4_Numbers There is also an example for FB Protocol Send ( to send data to another device) in the same examples folder. DanT
  17. Hi; SAMBA is a very stripped down version of a regular Vision ( V350, V430, V700) PLC with "severe " limits on usable memory. SAMBA is meant for small stand alone projects. Just a few differences ( for a full listing of the limits, refer to a SAMBA Spec Sheet ) SAMBA Vision( ex V350) MB 512 8192 MI 256 4096 ML 32 512 MF 24 64 HMI Screens 24 1024 micro SD Card NO YES I/O Expansion NO YES UniStream B3 Series has limits ( Check the Specs), but the B5 and B10 models have lots of space. DanT
  18. Hi; Net 3 -- Protocol Scan Why are you using the 1 second pulse to scan? This means your program only runs this every second for 1 scan cycle. Data can show up anytime! Remove the 1 Second Pulse and let it run free and collect the data as it comes. Consider using the session complete MB4001 to copy data to the COPY BUFFER in a new net DanT
  19. Hi; Here is where to look for information : Programming Examples : Help - Examples - V900 - Project Examples - Communications - EX-RC1 > Examples there to work with. EX-RC1 uses the RS232 Programming port to set the program inside Note : 57k Baud Rate MAX !! Just a note: Analog Data is sent as integers and received as integers Inputs and Outputs( Bits) are encoded to Bytes ( 8 Bits = 1 Byte) asent and then decoded at the other end. So pay attemtion as to where the data ends up. Once Understood, it works. Canbus Wiring : Review Help - CANBUS -- Getting Started with CANBUS - Specs and Wiring. Use Proper CANBUS/Devicenet Cables. CANBus cabling is NOT Powered by the PLC, so POwer must be applied to the CANBUS Power Wire Pair Review the Addessing for the Module and the PLC If you have issues, you can Post Your Code for assistance. DanT
  20. Hi; Info Mode tells a lot about what is happening inside a Vision PLC Touch the scteen ( in a Non Programmed Touch Area ) for 5-10 Seconds Enter Info Mode / Calibrate TouchScreen Appears Enter Info Mode -- Password is 1111 New Screen with menu appears. Version - Software gives info about the OS and installed Program Flash memory -- tells if program is backed up in Flash Memory Explore the others to get familiar with the PLC status DanT
  21. Hi; Any M91-2 ( Example M91-2-R1) has High Speed Input. The High Speed Input (HSI) can be configured to provide Frequency - in hardare setup You can then convert ( with a bit of Math, or Linearization function) this number into the parameter you need in yor project ( Example Meters/Min ) Under Help there are Example Programs DanT
  22. Hi; There appears to be a Ethernet/IP Library for Python Available -- Google it. Another method is using Modbus ( Python Library available - Google it) Ethernet or Serial DanT
  23. Hi; I recently ran into a similar issue In VisiLogic involving project restores giving me similar disk full messages. I did the following : Project Restore delete some of the older projects DanT
  24. Hi; "Yes, I have a copy that was saved which is what I attached, so that supposedly is the same as the one currently loaded " Use Info Mode to look at the program name that was last loaded Touch any spot on the screen ( Not used for a programmed Touch action) for 8-10 seconds Info Mode ( Password 1111 ) Version, Software Project Name DanT
