1 PLC and 2 URB-TCP

[Ruslan]

Hi all ,

I've got a PLC V350 and 2 URB-TCP  with discrete and analogue inputs/outputs modules.

How do I configure this in Visilogic?

Thank you for link.

 But I mean not URD-TCP2, I mean URD-TCP - 2 pcs. located in 2 different places.  Can I connect URD-TCP- 2 pcs. to PLC.

PLC has only 1 socket № 0 for URD connection. May be has a decision how connect 2pcs. of URD to PLC?

It can be done. I'm using multiple URB-TCP modules with one V700.

Give each URB a unique IP address. Configure a socket for each URB module and set up a Modbus config block for each. Use a TCP/IP connect block to connect to the URB modules address.

Of course there are other ways to do it but this is what has worked for me with a V700.

Also, I thought the modules were set up with 2 physical ports, done to allow easy daisy chaining.  If I'm mistaken on this, apologies.

Have you got this pdf?  It appears to be a precis of the larger official one.

Hi JPG,

 

I've got PLC V350 and URB-TCP -  2pcs. URB-TCP- I connected to  0 and 2 socket of V350. But If I load programm for 1st URB, after 2nd URB, then 1st is disconnect.  

If I load 2nd URB, after 1st URB, then 2nd is disconnect.

Could you give me example, please, how you made it? I think that I've got issue with settings of connection in ladder

Post your code here so we can take a look and give advice

Yes, you right.

When configuring second URB, make sure do not overlap PLC addresses (XB, XI) assigned to 1st URB. You can manually modify those operands.

Attached edited file. Only modified those rungs associated with sockets and modbus config. I did not check addressing nor structs.
