Hello, I'm currently working on establishing communication between a PanelView 300 and an Allen-Bradley Micrologix 1500 LRP PLC. Here are the details of my setup: - **PLC Model:** Allen-Bradley Micrologix 1500 LRP - **HMI Model:** PanelView 300 - **Catalog Number:** 2711-K3A2L1 - **Serial Number:** B - **Revision:** A - **Firmware Revision:** 4.41 So far, I've successfully connected the Micrologix 1500 to my laptop using a 1761-CBL-PMO2 cable along with a serial to USB converter and the DF1 protocol (USB Port 4). Additionally, I have established communication between the PanelView 300 and my laptop using a 1747-UIC interface converter with the DH485 UIC protocol (USB Port 5). **My Question:** I need guidance on how to connect the PanelView 300 to the Micrologix 1500 PLC effectively. What type of cable and communication protocol should I use for this connection? I also possess a 1761-NET-AIC Advanced Interface Converter, but I am uncertain about how to implement it. I noticed that the Micrologix 1500 LRP features an additional communication port (Channel #1), but I'm unclear on how to utilize it. Any advice or recommendations would be greatly appreciated. Thank you, QASIM
Thank you for sharing the complete part number: 2711-K3A2L1. This refers to the earlier PanelView 300 terminals, which feature a compact display and a numeric keypad, unlike the more widely recognized PanelView 300 Micro. The "2" in the part number indicates that this terminal includes true Data Highway 485 networking capabilities, facilitating connections to RS-485 style electrical systems. You will find an RJ-45 port for connecting your 1747-UIC, as well as a modular "AMP" connector jack for integration with a classic 1747-AIC isolator. Additionally, the 1761-NET-AIC enables connectivity between this terminal and your MicroLogix 1500 controller by converting DH485 signals (through the 6-pin screw connector) into RS-232 electrical signals. For a hassle-free setup, follow these steps: 1. In RSLogix 500 software, configure Channel 1 (DB9) on the MicroLogix 1500 to use the DH485 protocol. 2. Use a null-modem serial cable, such as the 1747-CP3, to connect Channel 1 on the MicroLogix 1500 to the DB9 port on the Net-AIC. 3. Connect the Net-AIC to the PanelView using either the 1761-CBL-AS03 or -AS09 cable (or a compatible alternative), linking the six-pin Phoenix style connector to the RJ45 jack on the PanelView 300. This configuration allows you to keep the MicroLogix 1500's Channel 0 serial port connected to your computer via the USB interface using a 1761-CBL-PM02 cable, while remaining in the default DF1 Full Duplex mode. Additionally, it enables simultaneous connections for troubleshooting on both the PanelView 300 and your computer with the PLC controller. Alternatively, you can connect your computer to the secondary port of the 1761-NET-AIC using the RS232 connection from the 1747-UIC, allowing you to download directly to the PanelView. This approach ensures a smooth integration of your PanelView 300 with the MicroLogix 1500 for efficient operations and troubleshooting.
Thank you for your prompt response! Based on your suggestions, I have designed a schematic that incorporates the cable names you provided. Please take a look at the attached link to review it. Does this look accurate from your perspective? Additionally, I currently do not have access to the 1761-CBL-AS03 cable. Are there any alternative options available, or will I need to place an order for this specific cable? I truly appreciate your assistance again. [View Schematic Here](https://ibb.co/iAfTYy)
Absolutely! The 1761-CBL-AS0x cable is incredibly straightforward to assemble on your own, thanks to the accessibility of RJ-45 connectors and six-pin Phoenix Combicon plugs. These components are readily available and easy to source online. For further details, visit: [PLC Talk Forum](http://www.plctalk.net/qanda/showthread.php?t=45862).
Sure! I will start by creating the cable and will keep you updated. Thank you!
Subject: Clarification on 24V DC Supply for 1761-NET-AIC Converter Hi Ken, I wanted to clarify whether I need to supply a 24V DC power source to the 1761-NET-AIC Converter. Thank you!
Hey Qasim! It sounds like you have a solid setup going on. To connect your PanelView 300 to the Micrologix 1500, you can use a 1747-CP3 or 1747-CP1 cable for DH485 communication. Since you already have the 1747-UIC converter, that should help facilitate the connection quite nicely. As for using the 1761-NET-AIC, it can help extend the DH485 network if your distance is greater than what’s typical. Just make sure you configure your baud rates correctly on both ends, and you should be good to go! If you want to utilize Channel #1 of the Micrologix 1500, you could also consider using it for DF1 protocol, which means you’d need to connect directly to it using the right cable. Let me know if you have any more questions!
Hey Qasim! For connecting your PanelView 300 to the Micrologix 1500, you’ll usually want to use the DH485 protocol, especially since you already have the 1747-UIC. The AIC is great for extending your DH485 network, but make sure to set it up correctly as a bridge between the HMI and PLC. You can connect the PanelView directly to the AIC using a DH485 cable; just remember to check that the baud rates match on both ends. If you haven't already, don’t forget to configure the communication settings on both the HMI and PLC to ensure they are set to talk to each other. Let me know if you run into any specific issues!
