PLC profiles

This library supports all KV series models. Device ranges differ by model. You select the device-range catalog by passing a canonical PLC profile name such as keyence:kv-7000; the library does not query the PLC to choose a profile for you.

Supported PLC profiles

Canonical profile	Key available devices	Notes
keyence:kv-nano	R, B, MR, LR, CR, CM, T, C, DM, W, TM, VM, VB, Z, CTH, CTC	Standard KV-NANO profile. EM, FM, ZF, and AT are not in this profile.
keyence:kv-nano-xym	X, Y, M, L, D, plus standard KV-NANO devices	KV-NANO profile with XYM aliases. E, F, ZF, and AT are not in this profile.
keyence:kv-3000	R, B, MR, LR, CR, CM, T, C, DM, EM, FM, ZF, W, TM, VM, VB, Z, CTH, CTC, AT	Standard KV-3000 profile.
keyence:kv-3000-xym	X, Y, M, L, D, E, F, plus standard KV-3000 devices	KV-3000 profile with XYM aliases.
keyence:kv-5000	R, B, MR, LR, CR, CM, T, C, DM, EM, FM, ZF, W, TM, VM, VB, Z, CTH, CTC, AT	Standard KV-5000 profile.
keyence:kv-5000-xym	X, Y, M, L, D, E, F, plus standard KV-5000 devices	KV-5000 profile with XYM aliases.
keyence:kv-7000	R, B, MR, LR, CR, CM, T, C, DM, EM, FM, ZF, W, TM, VM, VB, Z, AT	Standard profile for KV-7000, KV-7300, and KV-7500 family models. CTH and CTC are not in this profile.
keyence:kv-7000-xym	X, Y, M, L, D, E, F, plus standard KV-7000 devices	KV-7000 profile with XYM aliases. CTH and CTC are not in this profile.
keyence:kv-8000	R, B, MR, LR, CR, CM, T, C, DM, EM, FM, ZF, W, TM, VM, VB, Z, AT	Standard KV-8000 profile. CTH and CTC are not in this profile.
keyence:kv-8000-xym	X, Y, M, L, D, E, F, plus standard KV-8000 devices	KV-8000 profile with XYM aliases. CTH and CTC are not in this profile.
keyence:kv-x500	R, B, MR, LR, CR, CM, T, C, DM, EM, FM, ZF, W, TM, Z	Standard profile for KV-X500, KV-X520, KV-X530, KV-X550, and KV-X310 family models. AT, VM, VB, CTH, and CTC are not in this profile.
keyence:kv-x500-xym	X, Y, M, L, D, E, F, plus standard KV-X500 devices	KV-X500 profile with XYM aliases. AT, VM, VB, CTH, and CTC are not in this profile.

How to select a catalog

using System;
using PlcComm.KvHostLink;

var catalog = KvHostLinkDeviceRanges.DeviceRangeCatalogForPlcProfile("keyence:kv-7000");
Console.WriteLine(catalog.PlcProfile);

Select the canonical profile in your application settings, project file, or UI. Connect separately when you need to read or write PLC data:

using PlcComm.KvHostLink;

var options = new KvHostLinkConnectionOptions("192.168.250.100", 8501);
await using var client = await KvHostLinkClientFactory.OpenAndConnectAsync(options);
ushort dm0 = (ushort)await client.ReadTypedAsync("DM0", "U");

Model-specific cautions

KV-NANO profiles do not include EM, FM, ZF, or AT. Use DM for first reads and check the device range catalog before using model-specific areas.

KV-3000 and KV-5000 profiles include AT, CTH, and CTC, but timer/counter preset writes (WS/WSS) are documented for KV-8000/7000-series only.

KV-7000 and KV-8000 profiles are the documented profiles for timer/counter preset writes (WS/WSS). They do not include CTH or CTC.

KV-X500 profiles do not include AT, VM, VB, CTH, or CTC. Check Gotchas before using AT or XYM-style addresses.
