communication issue

[chavez]

Hy all,

I am new around here so big cheers to every one...

I have problem with connecting to my plc v1020 via ethenrnet port. I am using v200-19 ET1 snap in modul.

I programmed it correctly and i can ping my Plc, but when i try to connect with him in visio logic or by my aplication i get comunication error.

In visio is standard communication error....Both devices are new and i am the first user.

Can anybody help me??

Thank You very much

What do you have for Socket Inits? Are you trying to connect with port 20256?

Welcome to the forum!

Also check firewall settings on your PC, turn off the firewall temporarily to start with.

Thank you for answer... last night about 1AM 0'clock I solved the problem. I used socket 20257 becasue 20256 was in use (I progamed in PLC 20256 to be used ?!?), and I must use start bit to initialize network. It isnt like in webinars

Another problem I have is with readWrite function for reading MF registers for my SCADA program which i progamed in C#. I have examples for MI MB nad other Registers, what's the form for reading and writing in MF registers?

Thank you alot for help.

I can if need explaine more how I solved the problem.

- Make sure PC is on the same subnet as the PLC address.

- Use socket 1, port 20256, at least initially until you work out all your connection issues.

- Some PC firewalls can get stubborn and will want you to be on the 192.168.1.xxx subnet - try that (on both PC & PLC) if you aren't already.

- Check your cables. You need a crossover cable unless you're using an ethernet switch.

- Check your System Bits 141-150 to confirm that the ethernet card is present, initialized, socket initialized, etc.
