Hi;
In the Ribbon starting with Boolean, go to the end and under FB's there is Protocol
Protocol is a method to compose messages to be send or received over the Serial Port.
You can create simple or complex messages depending on the device you are communicating with and it's
methods of sending and receiving messages.
You can also receive and decode the messages from the device.
Variables ( MI's, MB's, and others ) can be inserted or extracted from the messages.
Review the Help for Protocol, and the Example programs ( Help - Examples - Communications - FB Protocols )
to learn how to effectively use this function.

Hi;
The issue may be the OS in the PLC is newer than the Version of UniLogic you are using. ( example - OS in PLC is from 1.31.116, and you are using 1.26.90)
Program version, UniStream Version, and PLC OS Version must ALL be in synch.
( Not like VisiLogic where a Newer OS in the PLC can accept an older program from an earlier version)
Check the OS in the PLC against the Version that UniStream has in it to install to the PLC.
2 Choices: -- Load the OS from 1.26.90 onto a USB and install it into the PLC ( May have to force the install)
-- Upgrade UniStream to latest version and install the latest OS into the PLC and Upgrade your program.

Hi
In U90 Ladder program, Look under Help - Examples - Flow Totalizing..- Tank Level Single Pump Example.
This will answer your questions.

Hi;
Go into Info Mode and nuder settings check the COM RS232 parameters

Hi Goldic;
What PLC are you Using? - Only 1 Comport?
If you can install the 2nd COM Port and use it to Communicate with your devices, then it will be so much easier for troubleshooting - worth the money.
Having the 2 com ports allows you to monitor the device communications a lot better.
If your PLC has Ethernet Port Installed, then Use Ethernet for Programming and Com 1 for Devices.

Hi;
V120-22-UA2 is actually 500Hz PWM Max.
PWM output is 24 V, PNP, so it is Limited -- also slow for a servo input, and wire the Servo Input accordingly
PWM freqency is xxx.x Hz 500 Hz is set as 5000 (500.0 Implied decimal)
PWM Duty Cycle is xx.x% 50% is set as 500 ( 50.0 implied decimal)
If you have an oscilloscope available - look at the waveform, especially if you want to push it above 500Hz !
You will have to use a counter to control the pulses and turn the PWM On and OFF.
The V120 is an older unit and was not designed to really work with a servo.
The V130-J-TR20 has better PWM High Speed Outputs - NPN - 200kHz, also some functions for basic servo control.
If you also need the Analog Outputs, then the V130-J-TRA22 - NPN 200kHz. The TRA has some functions for Servo Control.

Hi;
The Sensor is PT-100 and will NOT interface directly to the USC-B10-TR22.
You can add the UIS-04PTN PT-100 Module, or find a way to communicate with the USB-PT-104 they supply.
( I do not see an English version of the documentation)

Hi;
The V120-22-UA2 has 2 Comports.
Use COM1 for Programming and Online troubleshooting.
Configure COM2 for RS485 ( See Instruction Sheet for Jumpers to Set)
You can use MODBUS to move Data between the units. Just watch the timing , Search MODBUS in the forum
and there are several vey helpful topics by the experts about good practice in timing Modbus Calls.

Hi;
V120 Series cannot do Ethernet.
Look at the V130-J-TA24 + V100-17-ET2 ( Ethernet Card) LCD Screen, Keypad
or
V350-J-TA24 + V100-17-ET2 ( Ethernet Card) 3.5 inch Colour Touch HMI
If the program is small and compact, look at the SAMBA Series
VisiLogic has methods to convert existing program from V120 to V130 or V350 Color - Ladder OK, then Modify the screens
Also look at the Software Developer Tools under the Visilogic downloads for .NET drivers and Active X tools.

Hi;
Have you checked out the examples under Help, Sample U90 - Modbus.
Also Check Help -- MODBUS -- Copy to Google for Translation if a Help Version is not available in your language.
Also Look at -- Special Functions -- Modbus Commands are done as Special Functions using registers(SI's)
U90 Ladder does NOT HAVE function blocks like VisiLogic.
In U90, the Modbus function does the translation from MI 1 to the Modbus register number and reverse

Hi;
The UCR 5 and 8 Routers from Unitronics do not yet have any interface for Vision support for SMS messaging.
Has anyone done SMS messaging for a Vision thru the UCR Routers ( or the Routers they are based on).?
There are some options within the Routers for SMS, but I have not been able to get them to work. I have tried several so far.
Curious about what method works. ( Tried Protocol TCP via SMS Gateway-Post- looks do-able, but missing something, Email to SMS - cumbersome to implement - no success)
SMS can be done Manually, but this is within the router itself, that works.

Hi;
I doubt that Unitronics will put TRAIC outputs in t heir PLC's. All their designs are based on 24 VDC with some 12VDC units. - which makes then universally adaptable.
The Remote I/O Ethernet based, URB-TCP do have AC Solid State Output modules.
Other option is PNP outputs from the PLC and I/O and use solid state relays. ( more costs effective to replace a blown relay than a whole PLC.)

Hi;
If you download the UniStream Examples .zip file, there are several examples of how to import and use global variables within C Functions.
The Examples .zip file is just below the UniStream Download on the Unitronics Website.

Hi;
The Data from the Scale is being sent as an ASCII String ( Not an actual Number - ML or MI)
In Info Mode in the PLC, look at the Serial Port Monitor and see what the data being received there looks like.
Receive as a Stream of Vector Length 3 ( convert 2 Bytes to Linked Element(MI) ) with the CR,LF as the End of Text(EOF)( Length 2)
Make sure the 4th MI is set to 0x00 NULL >> 12 34 56 0x00 (Note: You can look at the MI's On Line in HEX Format - easy read for ASCII Data)
THEN convert the ACSII String to an ML in the ladder. >> Strings ASCII to Num
( Have an ASCII Table handy ! )

Hi;
For the HMI
Under Text, List of texts
Create an Indexed List and call them by the FaultCode ( int 32) ( your switch case index ) in the program
( FaultCode being what ever name you choose )
In the Ladder - Use the Compare = to Set the Fault Code to the Fault number
or -- this one is neet --
Under Solution explorer use the Switch Case and set up the FaultCode to the List of Texts
There is a lot of flexibility in this function - Fixed compares and ranges with Options for Actions
Example : Case ID 1 , Name Case 1, Comparison Type - Value , From #1 ( a Constant), To (Blank) , Action (Store Tag) , Tag (FaultCode) Store into Tag ( #1 a Constant)

Hi;
What is the electrical environment around the PLC?
High Voltages?
VFD's
Contactors switching high voltages?
Suppression on relay coils?
EMI filtering?

Hi;
Under Screens, Numeric Elements, there are 2 IP Address Options
IP Address Edit -- you can select which IP Address to view and edit ( IP Address Type)
IP Settings Edit -- Panel, CPU, DNS -- View and edit
These are all editable from the screen
In the Ladder - Strings -- IP to String and String to IP ( no info in Help for explanations)
IP to String allows an ASCII Variable
ASCII to String -- does not allow setting a Panel IP -- from what I can see.
( Don't have UniStream to play with right now - else I would test them out )

Hi
Define the failure more explicitly.
Power failure?
Touch Screen scratched and struck on an X-Y point?
Moisture Ingress?

Hi;
Do not know of a ready made example, BUT :
Help - Examples- V900 - Projects - Communications - EXF-RC15 - 2 examples there, modify and rename the IN and OUT Subroutines and add a 2nd set for the 2nd RC15.
Modify the MB's and MI's etc. for the 2nd RC15
locate how to change the CANBUS address for the 2nd module

Hi;
Comment for future :
from the comment in 1st post : The only thing I haven’t tried, is swapping out the plug in I/O board with one of the other known working units, to find out if it's the I/O or the PLC itself. I am nervous about trying this as I can’t afford to have a second one fail if something has caused a component to blow.
The I/O board Analog Inputs and Outputs are factory calibrated and data stored on the Main Board.
Swapping I/O board with another unit's I/O board will mess up that calibration, and Analogs May Not Work at all.

SM70-J-T20 Hi Speed Counter Input
in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Posted
Hi;
How fast are the inputs counting? What is the Pulse duration?
Input 8 and Input 9 are NOT meant to be High Speed Counters.
( True - they can be used for Very Slow Counting applications with long input signals)
Inputs 0-1, 2-3, 3-4 ARE the High Speed Inputs. These Inputs can be Normal Inputs OR High Speed Inputs
High Speed Inputs are set up in the Hardware Configuration.
Look in Help -- High Speed Counters - to see how to set them up and the explanation of each option available.
Change you wiring to the High Speed Counter Inputs.
Also review the Installation Sheet provided with the PLC.
