    How to add Ethernet to a SLC-500



    The SLC-500 is a very popular PLC with over a million installed processors in facilities around the world.

    Over the years many of those facilities have modernized their sites by adding plantwide ethernet networks, and I often get calls asking how they can add their legacy SLC-500 systems to those Ethernet networks.

    Ethernet adding to SLC-5/04 with both channels used

    Good day Shawn.
    We are replacing a PLC5/40E with BASIC card to a serial printer, RIO modules for IO, and a DH+ HMI, and Ethernet for data collection, with a SLC system.

    I wanted to use a SLC-5/05 to get Ethernet, but would lose the HMI connection, and cannot find a reasonably priced Ethernet to DH+ solution.

    To maintain the existing HMI, I can use a 5/04 - giving me its serial port for the printer, and its DH+ for the HMI - add a RIO scanner card, for the IO. But now I lose the data collection requirement. Unfortunately, since its RS232 port is going to be used for the printer, a NET-ENI is not an option.

    Any ideas?

    Good morning @RoTaTech,

    Sounds like you need RS232 Serial for the Printer, Ethernet for data, and DH+ for the HMI, but as you said an SLC doesn't come with all three, and the ENI is out because you have to have the serial port :-(

    - Question: Does the HMI have another communications port?

    Many people have PVPlus HMI's and don't realize how easy it is to change them from DH+ to Ethernet or DF1. However if you have a legacy HMI with only DH+ you'll likely need to stay with the 5/04 unless you have the budget to update it to a PVPlus 7 (there are some lower cost options which allow you to import legacy PV projects.)

    - DH+ to Ethernet options

    There are quite a few options in this area under $2K including the Prosoft and Automation Networks. While these may seem pricey, the could be less expensive then upgrading an HMI, writing Basic code, or even buying the now expensive ENIs:

    http://automation-networks.com/autom...rks-anc-100e-2

    - Serial

    Finally, you could use the old ENI on the serial port and use a 1746-BAS module with similar code that you had in your 1771-BAS module. As far as strict 1746 ASCII modules it looks like the ones I'm familiar with are obsolete.

    I also haven't tried a SLC Ethernet MSG to ASCII output device, but you may want to check out this article to see if the device he used would work with a SLC:

    Another option may be to use a 1747-DPS1 Port Splitter Port splitter on a SLC-5/05 channel 0 with ASCII on one port and the ENI on the other. Check out the information below to see if it would work in your app:

    Hope this helps!
