vijeo connection to a twido help

Jeff23spl · Apr 7, 2010

Hello Schneider specialists

I would like to know the best ethernet driver i should use to connect my twido to my XBGT4230 hmi using ethernet cable and a switch.

I'm also reading on the way to export from twido and import in vijeo tag database to use it on vijeo, is there a simpler way to do it ?

Thanks

ps is it me or Vijeo use a plateform similar to GE proficy ?

I presume we are talking about Vijeo Citect SCADA are we ?

Vijeo Citect comes with Schneiders OPC server, OFS, you could use that, i would personally use Modbus TCP, in Citect it is the Modnet driver.

Its more likely that GE use a platform similar to Vijeo, Schneider bought Citect a few years back and have given it a new name, Citect is used under license by numerous people.

OK, i presumed wrong !

Just add a Modbus Slave TCP device under IO Manager and point it at the IP address of the Twido, job done.

i tried it before you answer back but when i try to import my tags, it give an error message about register syntax....

I did some try and found xway tcp working with the twido tag syntax. I'm just about going to test it if it works

I'm just afraid of the Xway adress (station # and gate #) but i left it the way it comes and i will see during the test...

I'm also looking for a go to screen function about 1 hour ago to navigate in different page without any succesfull result...

I'm trying to do an accelerate learning to this product since i need to do the commisioning on next monday...I didn't bought the equipement so i cannot have direct suport from Shneider....Also the help file isn't so much intuitive for my level on these products...

All the help availaible is greatly appreciated.

after testing, the xway wouldn't work

i can ping both side equipememtn IP but the HMI didn't connect to the twido

I search for info in the help file and stll found nothing to directly help or give exemples. reference to other sections and others reference also to others section when opening a references....I will get crazy!!!

If someone had an exemple of a TCP connection between a Twido and XBGT showing both side config, it would greatly help me.
I'm afraid to continu all my pages without fixing this driver connection issue

i tried again a modbus tcp driver and if i manually match adressing it work just fine but i'm still wondering why the xway would'nt work using the same ip etc...

Jeff23spl · Apr 8, 2010

By the way if i want to use modbus tcp, is there a way to transfert binary adressing (%Mi) ? I found how to transfer real and double integer by inversing the second and first byte but how would i found adressing for %mi ?

Not sure with your hardare but modbus supports double integer.
I believe you can also do real as long.
Hopefully someone will chime in shortly and correct me.

i edited my previous post because i found the way...

all my data are only 32bits or 16 but the MSB and LSB get reversed in the communication on each side so i got bad reading. I just switched it and a miracle happened

I'm still looking for binary %Mi

next step is alarms and passwords and i will be set

Binary for modbus will be "Write" coil
r"Read" coilBut it is inneficient.
You'd want to read a whole block at a time instead of single "reads" "Writes"

This one looks better on here.

i don't understand your number under ()???

I'm not using a great modbus PLC is it just a Twido so all my holding register seem to be from 40001 to ? and i'm trying to configure it under vijeo designer 5.1.
Is my binary coil in the cpu (%Mi)start from 1 in the modbus tcp instead of 40001 for (%MWI) ?
