KEYENCE KV-8000 — PLC-side settings

KEYENCE KV-8000 — built-in Ethernet port.

What you need

  • Configuration tool: KV Studio
  • Network: Align IP address, subnet mask, and default gateway with your network environment.
  • After configuration: Power cycle the PLC to apply the new parameters.

Example values used in this guide

Parameter Example value Notes
IP address 192.168.250.100 Adapt to your network
Port 8501 Upper Link default

PLC-side settings

Screen: Unit settings

Parameter Setting
IP Address 192.168.250.100 (example)
Subnet Mask Match your network
Upper Link Communication Enabled
Port Number 8501

Full feature support

KV-8000 supports timer/counter preset writes (WS/WSS commands) and AT device access.

Connecting with this library

Parameter Value
Canonical profile keyence:kv-8000
Port (TCP) 8501
Port (UDP) 8501

Pass the canonical profile explicitly. The standard connection helpers do not infer it from the PLC.

Code example:

import asyncio

from hostlink import HostLinkConnectionOptions, open_and_connect, read_typed


async def main() -> None:
    options = HostLinkConnectionOptions(
        host="192.168.250.100",
        plc_profile="keyence:kv-8000",
        port=8501,
        transport="tcp",
    )
    async with await open_and_connect(options) as client:
        dm0 = await read_typed(client, "DM0", "U")
        print(f"DM0={dm0}")


asyncio.run(main())

using PlcComm.KvHostLink;

var options = new KvHostLinkConnectionOptions(
    "192.168.250.100", 8501, HostLinkTransportMode.Tcp, "keyence:kv-8000");
await using var client = await KvHostLinkClientFactory.OpenAndConnectAsync(options);
var dm0 = await client.ReadTypedAsync("DM0", "U");
Console.WriteLine($"DM0={dm0}");
