FLEXIHUB REDDIT SOFTWARE
It allows me to connect a USB port with an activation dongle (a very expensive software license) in my office to an HMI computer at the customer site via the Internet and a VPN (we use TeamViewer). There's a commercial product called FlexiHub that I have a subscription for to service machines we have deployed around the world. So it's entirely possible you could use a device that has both Ethernet and a USB port as a "virtual USB port" with USB redirection software, very similar to how you're running a virtual COM port now.
FLEXIHUB REDDIT FULL
The USB chipset inside the 1747-UIC isn't anything special, and it is running the very tolerant DF1 Full Duplex protocol over USB, the same as an old fashioned 1770-KF3 or 1747-KE would run over RS-232.
FLEXIHUB REDDIT SERIAL
You're already accessing the SLC-5/03 using a "virtual serial port".

You said that your goal is to be able to access both the SLC-5/03 and the PanelView 1000 from a comfortable and safe location in a control room, over the Ethernet network. you will find that passthrough has a limit on the size of messages that it can handle, and for that reason you can't use it to download/upload *.PVA application files to a PanelView Standard terminal. The SLC-5/03 controller actually does support DF1 Full Duplex to DH485 protocol "pass through" that allows you to access devices on the DH485 network from a connection to the RS-232 port.īecause you are using a virtual serial port, you can configure RSLinx Classic for the "KF3/KE" mode, not "DF1 Point to Point" mode, and enable passthrough in the status files of the SLC-5/03, and you could browse the DH485 network and see both the SLC-5/03 and the PanelView 1000.īUT. You can only connect one PC, because it uses a TCP/IP socket to transport serial data to that RS-232 port as a "virtual serial port".Ĭan you post exactly what make and model you have ? Instead, you have a virtual serial port server, which are simple and generic and inexpensive. That tells me that you don't have a "protocol aware" device like a 1761-NET-ENI that knows about EtherNet/IP and DF1 protocols. > I run out of ports to connect another ethernet bridge to PLC so I can modify PLC online There is not: that RS-232 port on the 1747-UIC has the same functionality (DH485 protocol only) as the RJ-45 port on the 1747-UIC, just with a different voltage and signal type. You asked if there might be a way to use the RS-232 port that's on the 1747-UIC to access the PanelView from Ethernet using an Ethernet/Serial converter. The "DH485 Programming Connector" is the RH-45 connector and allows you to connect a computer with PanelBuilder32 software via a 1747-PIC or 1747-UIC for upload/download purposes. The DH485 port works like you have described: the "DH485 Communication Port" is the flatter "AMP" connector that connects to the RJ-45 style connector on an SLC-5/01, 02, or 03 controller. These have the classic 2-plug DH485 network port and an RS-232 port that only supports line printers (it can't be used for upload/download). You probably have a 2711-K10G3 or -T10G3. You would connect the EtherNet/IP to DH485 gateway to a DH485 trunkline with three 1747-AIC isolators: one for the gateway, one for the SLC-5/03 DH458 jack, and one for the PanelView's DH485 Communication Port.

There are expensive ones (EquusTek and Prosoft) and they will require some extra wiring devices. Unfortunately, there is no EtherNet/IP to DH485 gateway that is inexpensive and easy to connect to your system. Welcome to the PLCTalk forum community, and thank you for all the excellent detail in your post.
