PLC profiles

This library supports all KV series models. Device ranges differ by model. Your application selects the catalog with 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

import asyncio
from hostlink import HostLinkConnectionOptions, open_and_connect


async def main() -> None:
    options = HostLinkConnectionOptions(host="192.168.250.100", port=8501)
    async with await open_and_connect(options):
        print("Connected")


asyncio.run(main())

Catalog selection is separate from connection setup:

from hostlink import device_range_catalog_for_plc_profile

def main() -> None:
    catalog = device_range_catalog_for_plc_profile("keyence:kv-7000")
    print(catalog.plc_profile)


if __name__ == "__main__":
    main()

Choose the canonical profile in your application settings, project file, or UI. Do not depend on runtime model probing for catalog selection.

Unsupported strings fail immediately. Use the exact strings in the table above.

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.
