[Socket status keeps in "Not Connected (19)"]

Hi;

  I see the note about   MB 0 being set by  SB2, 

   Are these nets in a subroute?  Is the subroutine being called?

   If not sure -  put a Incremental counter ( XI whatever)    at the top of the subroutine- attached to the rail.

        If it counts, the routine is /was  active.  If not counting, subroutine ius not currently being called.

Yess, it's called. As long as MB0 is high, the "start-up" subroutine is called (see attached picture).

For testing I've put the status of SB 142, (Ethernetcard Initialized), SB144 (Ehternet Socket 1 Initialized), SB151 (Ethernet status: Link) and SB148 (Ethernet socket 1: Connected) on the HMI.
Only SB148 stays 0 in my case.

Please post your PLC model #

V700 and other Vision plc (V350...V1210) has different Ethernet setup.

Sorry, forgot to mention. It's a V350-35-R2

[Socket status keeps in "Not Connected (19)"]

Hi,

For a test setup between my Laptop en a PLC i'm trying to configure an Ethernet connection. Easy peasy you would say. Well, apparently not.

Init of the TCP/IP card and the socket (socket 1 in this case) is all successful. 

I made the following settings on de PLC:
TCP/IP card init: IP address -> 192.168.0.1, subnetmask -> 255.255.255.0, Default gateway -> 192.168.0.254
Socket init: Socket 1, Protocol -> TCP, Port -> 20256, client/server -> client (master).

My laptop's IP address is set to 192.168.0.10

When I ping the PLC from my laptop is this successful.

The PLC is set als Master (intentionally). For testing I've also tried set the PLC to Slave. This had no positive result.

I can't find the reason why the socket status will not switch to connected. 

 

Explanation for the attached picture. please read MB0 as SB2. MB0 is set on start up by SB2. When all initialization is done, MB0 will be reset.

 

In advance, thanks for any help.

If the panel is not installed  to any control box, Flex prompts may help.

 

The panel is not installed at this point. But Flex prompts does not ring any bel to me. Care to explain a little bit more? Thanks.

spec of dirt under the screen protector film

Actually, i noticed that there is some wood dust under the under the screen protector. So that's one thing i can look at.

 

Really many thanks for the reactions so far

[Touchscreen problems V1210]

For some time now I have noticed that my V1210's touch screen has stopped responding

When in Online Test mode, and monitoring SI40 (Touchscreen touched on X-coordinates) and SI41 (Touchscreen touched on Y-coordinates), I noticed that SI40 returns the correct coordinates, but SI41 somehow always returns the value of 599 (bottom screen). 

Anybody overhere familiar with this problem? And maybe an solution?

 

Thanks for the reply.

It is another option - use PT100 sensor with embedded converter with analog output 0-10V or 4-20mA  and connect it to PLC ANALOG INPUT (3 item on i/0 board). 

I know, but I already have several devices for collecting temperature and humidity which work on the MODBUS protocol. So thank you for the reminder, but for now I stay with the option to find a V200-19-RS4.

This is V230 jumper location - please check inside if no lable and cover is solid

 

Yeah. I definately don't have that.

like Joe T mentioned, i think i have a model before 2012 which did not come along with a configurable RS232/RS485 port.

So nothing left for me then to try to obtain a V200-19-RS4(X). The only problem is that I live in the Netherlands. Shipping costs via ebay is almost as expensive as the V200-19-RS4 itself. 

In the Netherlands I can only purchase this item if I had my own company (which is not the case 😀). But i figure something out.

Thank you everyone for your contribution in this item.

I also see this in the manual.  Are they there on your unit, Leyke?

cheers, Aus

I saw that part to. But on my V280 model there is no small window.

Remove the Snap I/O module and then using a flat blade screw driver remove the back portion of the V280's case.    There should be two sets of jumpers beside one set will control RS232/458 for port two the other set will control the RS485 termination for port 2.

 

See page 8 in the linked.

I know the documentation. But that's just it, my V280 says otherwise as the documentation. I already removed the back end. Believe me, there are no sets of jumpers on my V280.

If I get the time, I will take a picture of it.

[V280, configure comm. port 2 for RS485]

Hi,

For personal use I'm using a V280-18-B20B with a V200-18-E1B. snap-in module. In order to register temperatures, I'm going to use a (third party) Pt100 I/O-module which communicates via MODBUS RTU. 
According to the documentation I would have to configure comm. port 2 of the V280, through jumper settings, for RS485 communication. And, again according the documentation, these jumpers must be present on the circuit board directly behind comm. port 1 and port 2. But unfortunately in my case there are no jumpers on my V280 to set comm. port 2 to RS485.

Several questions popping up in my mind:

1. Are there V280 models which don't have these jumpers to set comm. port 2 to RS485?
2. Is the documentation incorrect and do I have to look better (and on a different place) on the circuit board?
3. To communicate through RS485 with the V280, do I have to purchase the V200-19-RS4 Snap-in module (RS485 comm. board), because comm. port 2 is just not configurable for RS485 on the V280 (which I actually expect, because  the name at port 2 only indicates RS232. If port2 is also configurable for RS485, you would expect port2 to be labeled RS232/RS485).

In advance, thank you for your response.
