Thank you both Simon & Damian.
The signal is analog. The overrange is set at 5.5V & at this I am getting approximately 19 mA.

Hi,
I have an amplifier which outputs 0 to 5 V depending on the sensed condition. However due to an oversight, I had ordered EX DI16 AI3 TO16 module. This module has 3 Analog inputs of 0 to 20 mA. The amplifier specs state that its output impedance is 100 Ohm, the input impedance of the analog input is 190 Ohms. So on connecting the output of the amplifier to the analog input, I get a value of around 19 mA (978) counts in MI corresponding to the analog input. Is scaling the counts such tha 978 corresponds to 1023, the only solution? Or can the input be made to receive 20 mA?
Thanks

Hi,
Small tip: In advanced functions of FB Loadcell you have option "Disable all other chanels" This way you make one channel only runnning in LC3 with the speed of LC1.
Does this work also with the Analog Inputs in IO-AI4-AO2? & how?

Hi,
I am on a project where I need to interface a V570 with a PC thru VB6. Where can I get the syntax for reading & writing the values for MB, MI, ML & MFs.
Kindly help me on this.
Thanks

Hi,
Thank you both sgull & Simon. I have decided to take your advice & have asked for more clarifications from the concerned party. Hope they provide me with the right answers. This will help me decide if I would want to go ahead with the project.

Hi Simon,
Thanks for your reply. The requirement is for ATEX Intrinsic Safety.
I have not done anything like this before. Have only made straight forward panels for the indoor class.
Any further insight would be welcome

Hi,
I have to enclose a V130 33 TRA22 & a 24 V SMPS unit in an Explosion Proof Enclosure. What are the precautions that I have to take? Should I use Zener barriers? If so should I use them only for DIs & DOs, or also for the Analog I/ps & O/ps?
Pl help me on this issue
Thanks

Thank you R Moses, it works now

Thanks R Moses, my machine runs on Win 7 32 bits. I was previously using Visilogics 9.3.0 for quite some time on this machine. Its only after the upgrade that this has come about.
I may have to uninstall it & reinstal V9.3.0

Hi Zulu972,
You cannot use visilogics with M91. The correct software that will connect to M91 is U90.

Hi Joe,
I need a scanning speed of around 25 mSec for all 10 channels.

Hi,
I need a system with fast scanning of 10 nos. 12 bit analog inputs. My hardware is configured as V570 + EX-DI16A3-TO16 + IO-DI16A3-TO16 + IO-DI16A3-TO16 + IO-DI16A3-TO16 + IO-AI4AO2 + IO-ATC8.
My question is " will changing the configuration to V570 + EX-DI16A3-TO16 + IO-AI4AO2 + IO-ATC8+ IO-DI16A3-TO16 + IO-DI16A3-TO16 + IO-DI16A3-TO16, improve the scanning ".
Thanks & regards

Hi Ron,
I think the "bottle neck" here is not the PLC scan, but the conversion time of analog inputs.
Which hardware you're using for analog inputs? Did you check the conversion method and conversion time for the relevant hardware unit?
The scan time of te controller itself depends not only from the numbers of inputs and outputs, but the length of the program and type of operations. HMI also can affect a little the scan time.
Usually gthe "normal" scan time for enhanced Vision OPLC is in range 3-7 ms.
Thanks Emil,
I will be using 2 X IO AI8 in the fast mode. It mentions 25mSec per input. What does it mean? 8 inputs would take 200mSec?

Hi,
I will be using V1040 with around 64 Inputs, 64 Outputs & 12 Analog Inputs. The actual usage would be around 30 Inputs, 24 Outputs & 8 Analog Inputs.
The process involves comparing the 8 analog inputs and carrying out the associated procedure. The analog inputs are connected to sensors which have an output response time of 75 microseconds in the 0 to 10 V range.
What will be the PLC's scan time for such a configuration?
Pl comment.

Hi,
Not all USB to serial adapters work wit JAZZ Models. The adapter needs to be able to handle the extra RS232 signals also. Change your USB to Serial adapter & try

Hi,
Is it possible to use any of the Vision series PLC to print a Graphical Logo using an Ink Jet Printer?
How?

Hi,
I am running Vislogic 9.3.0 on3 computers. Of which one is a new laptop, with Windows 7 Ultimate installed. On this laptop, i receive the following error
12Invalid Tools collection index.
What is this error & what is its remedy
Thanks

Hi Emil,
One thing I have found with Unitronics and Visilogic when introducing it to new customers. If I introduce it to someone with little or no PLC experience, they tend to pick it up easier because they don't have preconceived expectations. On the other side, introducing it to people with a lot of PLC experience often doesn't go so well. You hear phrases such as, "you mean I can't do this", or "this isn't very intuitive". It's a tougher sell, because they are already aware of things that they can do with other products that they can't do with Visilogic.
Hi,
This is very true!
