This document is about the Keyence KV/KZ Series human machine and the connection with various brands. It introduces the communication protocol between the human machine and various brands, including communication speed, controller station number, control area/status area, and controller wiring instructions.
This manual provides a reference for the KV and KZ series PLCs, describing the communication parameters, RS‑232 interfaces, and the register definitions used for programming and monitoring. It includes tables of registers, timers, counters, and relay points, as well as notes on differences between the KV and KZ models.
The document notes that the KV/KZ series uses a 9600‑baud, 8‑data‑bit, even‑parity, 1‑stop‑bit RS‑232 link, with D‑SUB connectors on the DOP side and RJ‑11 connectors on the controller side. Revision information and specific access restrictions for certain registers on the KZ series are also listed. This manual is written in Japanese.
| Communication speed | 9600 baud, 8 data bits, even parity, 1 stop bit |
|---|---|
| DOP connector | 9‑pin D‑SUB (RS‑232) |
| Controller connector | RJ‑11 (RS‑232) |
| Document revision | August 2010 |
The series uses 9600 baud, 8 data bits, even parity, and 1 stop bit over RS‑232.
The DOP port uses a 9‑pin D‑SUB RS‑232 connector, while the controller port uses an RJ‑11 RS‑232 connector.
No, timer registers T‑10 cannot be accessed on the KZ series.
No, counter registers (C‑*, CTH‑*, CTC‑*, PC‑*, PCTC‑*) are not accessible on the KZ series.
