[Samba Analog input: Sourcing or Sinking]

14 hours ago, Jeff164 said:

• 24 volt power to pin 1 of transmitter from instrument power supply.
• 0 vdc to pin 2 of transmitter and pin 2 (0V) of Samba input terminals 
• 4-20 mA signal from pin 3 of transmitter to pin 10 / I5 of Samba

And JP4, JP10 set to B - enough to get the right analog signal in "Source" transmitter mode. Please Note I5 >>>>> AN3 analog input.

All Samba jumpers will be set to B except 11. 

I think you want to setup 3 channel temperature mesurement via Samba. In your configuration present Two PT100 sensor and you need to use transmitter for set channel #3 PT 100 to 4..20mA and connect it to AN3 analog input.

If it is true - you must set J11 to B also.  

Then you can connect both #1 and #2 PT100 sensor Common wire to CM PT100 (I11 Samba pin).

Tech literature with the transmitter shows that it is selectable to be configured for a sourcing or a sinking analog input.

Please post transmitter model numbers or manual in pdf format.

[USP-070-B10 7" HMI and USC-P-B10_H CPU for panel]

Please try to check default Ports

P/S It looks like some something block connetion. What PC type and Win version used?

 

P.S 1 Please try to separate PLC CPU from panel and connect to separated panel.

[Logic operation: OR]

In this topic you can find link to Unilogic example. Please try to find example how Unilogic logic works.

[Logic operation: OR]

Hi,

maybe you do not know - Unitronics do not offer embedded simulator in Visilogic and Unilogic.

If you have Unistream on table - you can go online and test your code. You do not pay for software but must test program downloaded to  PLC.

If this function do not work in program downloaded to Unistream PLC - you have another rung in program with the same coil -(  )- Name or this subrouting is not called from main program.

Only one direct coil must be used in program.

 

In TIA you can use simulation and  run ladder without PLC. But you must pay for software licence and PLC separately.

 

[Samba 43 HMI Password HEX entry not working]

Standard solution

[USP-070-B10 7" HMI and USC-P-B10_H CPU for panel]

Try to use Ethernet cable. You can touch on right-up corner of USP screen for some time and find Uni Apps menu. In this menu you can find Ethernet connection IP.

Use it for Unilogic communication setup. 

 

About USB... If you try to install Unilogic without Run as Admin option  - some part of drivers can be blocked. 

On my PC if i connect USP via USB - Unilogic agent say about connected USP in down-right corner of PC screen.

 

[MicroPython on unitronics?]

As i know Unistream board run under linux.

I think Unistream not provide command line option on screen - It is Linux Based HMI+PLC.  Maybe remote terminal is possible, but it is Unitronics "know how".

[Connecting Zebra GK420t printer to USC-B10-TA30 via Ethernet/IP]

Hi,

Please print printer configuration. You can read in manual how to press button on power on.

Please post foto of this configuration. As i see maybe something wrong in printer input source. I sometimes have problem with not operational port on  Zebra (USB, COM or Ethernet). It is appear after automatic flash optimisation that printer do sometimes (if user sw off printer when it is performed - printer firmware corrupted).    Manual switch print source help to solve problem (if it wrong on paper).

 

[Save current time from a timer]

Please use demo project from Visilogic

V120_Store_Load_Timer_or_Counter.vlp  from Function example.

For store timer time left  SB2 -|/|-   system bit can be used.

After power on SB2 -| |- can restore timer value.

 

V120_Backing_up_a_HSC.vlp  demo Project in Visilogic  is helpful for understand how to store-restore operation work.

 

[Less than compare function not powering coil]

Please Find MB33 in Visilogic project.

I think you have another MB33 coil -(    )-  in project  (only one direct coil must be in project)   or do not add subroutine with this function into Main routine.

deletes all received SMS, not just the 'read' ones.

I do not know how you send test SMS to PLC.

In one of my project i use incremented number after "status" message.

Something like password001 - PLC send back password002..... I send this password002 to PLC - answer: password003 ect.

In this way only different message is stored into modem And i only copy message from PLC for check status -no need to type new one. 

Yes all message  is cleared after comm restart. But i always know last number and can send bigger one

[SMS SCAN reads always the same SMS over and over again]

In Com Initialaze screen you can see Clear SIM check box.

It looks like disconnect and connect to modem via active this check box - initiate SMS delete option.

You can  do com init, wait for SMS - send OK and disconnect for some time. After reconnect SMS message may be cleared.

[Negative modbus number to positive]

For correct answer heat meter model  or modbus manual needed.

You can use Swap Bytes function for ML90 and get result in DEC format.

[SMS SCAN reads always the same SMS over and over again]

Please try to use AT message for modem control.

AT+CMGD command is used to delete SMS messages, please read modem AT code format.

Moved ...

 

If you need to program Protocol message - best way to use Ethernet or second RS232 Port 2 for connection to Visilogic.

You can use SEND ans SCAN sequence from Visilogic Sample program.

Some tips about Protocol present on forum topics.

[Issue with VisiLogic Version 9.8.91]

One more tip...

[Issue with VisiLogic Version 9.8.91]

Is it appear if you start new project in 9.8.91 or only with 9.8.80 project opened in 9.8.91?

[Problems with RTC and password.]

The UniStream® platform comprises CPU controllers, HMI panels, and local I/O modules that snap together to form an all-in-one Programmable Logic
Controller (PLC).

USP-070-B10 is HMI panel - it is no battery backup RTC inside. CPU for panel (PLC CPU) with embedded battery  must be connected to panel for provide RTC.

Is it CPU connected to panel or you use only panel without PLC CPU?

[Wiring a 0-10V Pressure Transducer to a V200-18-E3XB Module]

Hi,

V200-18-E3XB has isolated Analog input.

If you use +24V (red sensor wire) from PLC power supply then you must connect ACM pin (connected to sensor black wire) to PLC  0V  (-24V).

Othervise you sensor is not powered and no signal present on sensor  analog 0-10V output.

You can also check V570 firmware version in .xls file provided by Ausman

I do not know  what changes in latest version.

 

[Vision V570 RTC to ASCII data history values fast blinking on screen after replacing old V570 to new one V570 with USB.Same programm,VisiLogic 9.8.65]

If it is possible to connect to old PLC - you can read operand and save it.

After download project to new PLC - you can write saved operand from file.

I think you simply do not remember  timer value setup  and if it resetted to 0 - blinking is normal behavior
