[rc snubber for io-ro16]

Hi all

I'm using v280 with IO-RO16 to drive the solinoid valve 220vac 11.5VA 28sets butI'm not sure the rc snubber value should be?

please advise the simple value or simle calculation,thank you

[Raw data of Loadcell A2D]

I'm using represent mode of load cell with raw data, please advise me

1. What is the maximum of A2D?

2.Are these raw data same as between difference capacity of load cells(15kg,30kg)

[MF resolution]

Thank you for your comments, I understood.

[MF resolution]

I'm using V280 with Visilogic 9.8.64 build0

I have the simple formula A(ML)x1=B(MF), I try A=2147483647 but the output = 2.147484E+9 why it's not 2.147483647E+9 because in the manual said maximum MF range is 3.402E37

Please advise, thank you.

[Could I re-order SI250]

Hi, Darknesspic,

 Try to delete them from HMI and place back in order you need.

 

^^Yes I use this way at the time, thank you.

Hi,

You can re-arrange keypad-entry variables. Use "Variables Tab Order"

Change variables order as you need.

Is this what you need?

 

^^ My Visilogic doesn't has this feature(my visi is 9.8.31 build0), please advise

 

[Could I re-order SI250]

When I place the key entry on the HMI and then 

(First time)First variable(variable10) would be SI250=0

(Second time)Second(variable11) variable would be SI250=1

(Third time)Third(variable12)  variable would be SI250=2

...something like that

But I want to re-order the variable again to 

(variable12) going to be  SI250=0

(variable10) going to be  SI250=1

(variable11) going to be  SI250=2

Is it possible? Please advise.

[Could I re-order SI250]

Dear All

I using V280, in HMI when I put the variable(key entry) on the HMI, the SI250 will automatically numbering. So, do I want to re-order SI250 again?

Thank you

[PTO Setting]

Hi all

    I'm using EXF-RC15 with PTO function, I need to control stepper motor with speed range 0.008-0.4hz so I want to clearify

    1. how to set "Unit" and "Pulses per Unit" in PTO config, and what meaning of these parameters

     2. What is relation of "Unit" and "Pulses per Unit" in PTO config and "Velocity" and "target" in PTO move

Thank you

[PTO and continuously run]

Hi All

      Thank you for every body,

     I have  tried clear the current position(in PTO Read Status) but I couldn't. Any body know how to do it, please advise.

[PTO and continuously run]

I have more question, Can I mix PWM and PTO together? for example, in the normal case I use PTO if I want PWM I stop PTO and use PWM.

[PTO and continuously run]

AlexUT, Thank you very much, I'm clear

[PTO and continuously run]

Hi

      I'm using the EXF-RC15 and I think I will use PTO feature but there is one task in the process need to run continuously(without target) and stop by user keys(master PLC in CANbus).

       Please let's  me know or give me some advice, thank you.

[V280 could not calculate floating point]

Dear All

 

        I'm using Unitronics V280 and Visilogic 9.5.0 Build0. It work fine(on V280 old one sparepart) but after I got a new one, I got the problem in calculation of floating point(MF) once I back to the old one it's work fine.

 

         Please kindly advise the solution,thank you.

[Read data from electronic scale]

I'm using V120 with scale that the scale send the data at all time and Unitronics will read the data but the PLC can not get the data. Please advise.

Init function block:Databit=8,standard=RS232,BaudRate=9600,Parity=None,IgnoreBreak,StopBit=1

Scan function block:no use STX,ETX and anther block same the sample

Please guide me.Thanl you

I need to start with PLC V280 controls the temperature by thermocouple typeK, please advise how to start. Thank you.

[Access V280]

1.I have a little confuse why we need to use OPC server because even we can access the memories of PLC by read/write command(ASCII format) serial communication with PC?

2.What cases we have to use OPC server?

Thank you.
