what is the Difference between timer blocks in quantum and unity PLC. While changing from quantum to unity, in case of off delay timers, whether inputs needs to be reversed? (NO to NC)

TSX17 in stop mode after power off
Hi there, I have a TSX17-20 that works great in run mode as soon as we shut down the power, when tsx restarts it goes in Stop mode (green light blinking). It's the only led blinking. All other leds (CPU,I/O mem, battery) are off.
I connect the plc to the laptop, I put it back in run mode, then the led become steady and everything is ok the plc and the production machine works until next power shut down, when we restart: again blinking stop mode.
We have a cartridge eeprom, we know the program is ok otherwise it would simply never work.
Any guidance would be helpful. Thanks

Master & Slave configuration between 2 PLC Twido TWDLCAE40DRF
I need solution for master & slave configuration between 2 PLC Twido TWDLCAE40DRF.
My final project is about a system for filling drink on a cup and do the packaging. the component of the project is the filling system (dropping cup, filling water, pressing the seal) and the packing (packing into a box and sealing the box). This project is using 2 PLC Twido TWDLCAE40DRF. My problem is how to configure one of them as the master and the other as the slave. I've read the manual book but it's hard to understand the instruction. if anyone can give a simplify explaination to me please reply this post or you can reach me at mail: tatangprayoga11@gmail.com

"Talking Modbus TCP/IP"
Hi Everyone!
Where are my experts?
I am undertaking a project at work. The project contains analog style motor positioning circuits (operational amplifiers, integrators, and other PI elements). Not that this is relevant to the post yet ;) .It's my first PLC project ever!
I am using the Schneider M258 with SoMachine 4.1
The PLC is talking to SoMachine via Ethernet (obviously I have a router between the PLC and my pc).I can Login and run the first POU I created. It's a simple And logic circuit for now.
I have a co worker (c programmer) agreeing to help me pass data from my PLC to a browser screen. Although he's not familiar with PLC he's quite skilled writing code. He has wrote a Modbus protocol which allows him to interpret Modbus commands on his desktop.
1) Do I Need any special hardware to pass the data out of the PLC into the Router then into his browser.
2) As a trial can I send him MODBUS commands regarding my AND circuit?
3) How do I create such a command?
4) Is it possible for him to send me Modbus commands to change variables inside my program?
5) Are there web browser "plug-ins" for this idea?
Thanks for reading and hopefully all of you can help me answer some of these questions.

Ladder Logic socket communication
Hi everyone, I'm a newbie in the ladder logic programming languages.
For my thesis project I've to develop a scenario but I'm stuck with the creation of a socket connection from the Modicon M340 PLC to a server for transfer continuous data given from sensors or similar.
Does anyone have a sample program that could have such a functionality so that I can change it based on my needs?
Thanks in advice for any further reply!

simulator in somachine
I just started working with somachine basic V1.5 SP1. I made a little program inside a POU with ladder. But when I open the simulator nothing seems to work. When I activate an input it doesn't seem to do aanything except making my contact green but it doesn't opperate annything that is placed behind it. Can someone tell me why that is?

converting word
I have a problem with converting a server word. I'm trying to put the seconds in my program trough %SW50. But this is counting like this:
0000 0111 = 7
0000 1000 = 8
0000 1001 = 9
0001 0000 = 10
0001 0001 = 11
But i forgot how this is called. How do i convert this to:
0000 0111 = 7
0000 1000 = 8
0000 1001 = 9
0000 1010 = 10
0000 1011 = 11
And is this second style integer?

"Ladder Logic" internal contact set-up
Hi Everyone,
I'm working on my first PLC program and I have gotten my hands on some ladder logic I'm trying to duplicate.
I'm using SoMachine 4.1 and have started a new Ladder Logic diagram POU.
I'm curious on how do I create internal contacts.
EXAMPLE:
24v--------l START BUTTON l----------------( COIL A)-----
--------------l COIL A CONTACT 1; attached to a real output, solenoid valvel-------------l COIL A INTERNAL CONTACT TO CLOSE l----------------
Are there standards for numbering and labeling?
I'm seeing L and U inside coil contacts. Does this have an underlying meaning according to standard?
Is there a RTO function inside SoMachine 4.1

triggering popup window with variable
i'm working with vijeo designer and i have a problem with popup windows. I'm trying to make a popup window appear with a variable. A bool to be exact. I want that a popup window appears when the bool becomes 1. But so far i haven't found a way to do that. Can someone help how I could do that? It's the meaning that that bool becomes 1 when there is an error and that the popup window appears then to let the user know there is an error. Or does annyone have a better idea?

changing time of schedule block
Hi,
I'm working in so machine basic v1.5 and I'm wondering if it is possible to change the start time and stop time in a schedule block with a %MW. So is there a possibility to for example say %CH0.??? := %MW5 in an operation block? And is there a page where u can see al the possible codes. I already discovered that %TM0.P changes its preset but i don't find a list of al those possibility's.

changing memory word with variable
Is there a way to choose with %MW you use depending on the value of %SW49? For example, i have 7 %MW:
-%MW4 that needs to be active when %SW49 :=1
-%MW8 that needs to be active when %SW49 :=2
-%MW12 that needs to be active when %SW49 :=3
-%MW16 that needs to be active when %SW49 :=4
-%MW20 that needs to be active when %SW49 :=5
-%MW24 that needs to be active when %SW49 :=6
-%MW28 that needs to be active when %SW49 :=7
so is there a way to say %MW0 := %MW(4*%SW49) on a operation block?

Unlimited counter
Hi.. I found very hard to make Unlimited counter for application that i trying to make.. My application it's empty pack system.. On packaging machine.. This counter is supposed to count finger at machine... When it reach its value.. It will reject.. Coz theres sometimes many empty product thats entere the package.. I make more than 5 counter..i try to make loop...the problem is.. When 5 counter already workw.. Sometimes when its start.. It doesn't want to count again.. I have to wait for 1 cycle.. Than it work again.. Does anyone knows how to solve this... Thank you

error 1850 when trying to activate web gate
hey,
I'm making a program with vijeo designer with a HMIGTO5310 and with somachine basic and a TM221C16R. At the moment i don't have my TM221C16R yet but i'm able to run the program in simulation on my pc and connecting the hmi to it. I'm able to control everything on my hmi but the moment i'm trying to activate the webgate, vijeo refuses to download the program to my HMI end gives the error " error 1850: [target] [target1] secondary drive full or not found. check the data file location setting.". Is this because it isn't connected to a real PLc but a simulation of it or is it because something else?

How to install a ''HOT FIX''
I want to work with the ''MODICOM MC-80'' and I have unity pro xl v11.0 but when I create a new project this PLC does not appear in the different options the program gives me.
In the data sheet of the 'MODICOM MC-80' it says the following:
1 Install Unity V8.1
2 Install the Hot fix: UnityPro_V81_HF_MC80
3 Create a new project with MC80.
I assume that for the version of unity I have should be somthing similar but I don't know how intall or even find a HOT FIX.
Thank you very much in advance.
