Allen Bradley SLC 503 to AHMI

[larryhts]

I am trying to connect to an AB SLC 503 using a MOXA EIP3270 module. I tried using the SerialDF1overTcpforSLCMicroCom and the EthernetIPforSLCMicroCom drivers.
I am trying to extend the distance for the connection. I am able to use the serial driver using RS232 a cable, but would like to use Ethernet to get more distance.
Has anyone used the MOXA EIP3270 module with AHMI before?

I have never used that particular device, but it looks like it would be similar to an ENI module and use the EthernetIPforSLCMicroCom driver. If it doesn't work, try using the latest 3.99y Beta version

If you are only using this with AdvancedHMI, a lower cost method is to use one of these with the SerialDf1OverTcpCom driver:

Archie  I bought the USR-TCP232-302 and It got here this morning. It works well with AHMI. I was trying to get the ability to use the Logix 500 over the same connection. I have a ticket in with MOXA. All their support is email first. I will post after I find out if there is a fix.
Thanks for your time

I think if you use the virtual com port driver, the USR can be used with RSLogix with the DF1 driver, but you then lose the ability to use AdvancedHMI simultaneously.

Archie, I down loaded the USR-VCOM and it works very well. I now have RS Logix500 running and AHMI app at the same time. Both are a bit slower but no conflicts. I won't have Logix500 running except to troubleshoot. Still waiting on MOXA's support. Will likely send the MOXA back. The USR is much nicer to set up.

Thanks

Does the VCom allow you to run both RSLogix500 and AdvancedHMI at the same time? I never tried the VCom software, but with COM ports I have only ever seen where you could run one software at a time.

[larryhts]

I can run both rslogix500 and AHMI but the through put is slower.

[Archie]

That's good to know because I would have thought once RSLinx grabbed to virtual com port, it would not let AdvancedHMI have access to it.

I have set up 2 SLC5/03's using Moxa's Ethernet serial port adapters. They get installed on the AHMI computer as a normal COM port and use the standard DF1 driver perfectly.

I am now getting an Error from the “SerialDF1overTcpforSLCMicroCom” driver that locks up the panel.

Not sure what’s causing it.

In the file AdvancedHMIDrivers\AllenBradley\SerialDf1overTcpForSLCMicroCom.vb  change line 261 to this:

Code: [Select]

If (e.Values IsNot Nothing) AndAlso (e.Values.Count > 0) AndAlso e.Values(0) Is Nothing Then

Thanks Archie, I'll change it today.

Thanks Archie, I'll change it today.

That code is actually just left over debug code. You can actually delete the 3 lines of code starting with the "If" to the "End If".
