Модул за управление на мрежи HHC-N8I8OP

1. Strong anti-interference ability, can be connected to external high-current AC contactor and relay, will not crash under strong electromagnetic interference.
2. The product is resistant to high temperatures and can work in the environment of -40 to 85 ° C.
3. Industrial grade products. Support automatic acquisition of IP.
4. The true 100M speed enables reliable communication with 0 delay commands.
5. Support 10 TCP client connections under the TCP server.
6. Through the provided configuration software, you can configure five working modes: TCP server, TCP client, UDP server, UDP client, DNS domain name.
7. 8-way relay, 8-channel digital input with full-open and full-off input. With power-down save function (save relay status).
8. With an RS485 port, it supports Ethernet to RS485 transparent transmission.

Configuration

By default the device has a simplistic non-Modbus plaintext "console style" protocol for querying the device. If you enable Modbus TCP mode via the configuration software, you can connect (using the same port) with Modbus TCP capable software.

Coils

The table below applies to the following Modbus function codes:

The following appears to be unsupported:

Attempting to read addresses 0-15 or 24-128 will not give a response. Reading addresses 16-23 is known to work, though it's possible there are more valid ranges further out in the address space.

Attempting to write addresses 256-280 will not give a response. Writing addresses 0-255 are known to work, but only the range 16-23 has an understood purpose at the moment.

Discrete Inputs

The value returned is whether or not a logic high (+5V) is present on the input. The "+5V" and "COM" (GND / 0V) pins must be powered externally.

NOTE: A pulse (to +5V) on Input #9 is an override to turn all relays on along with a red LED, until a pulse (to +5V) on Input #10 turns them all off.

Attempting to read addresses 0-31 or 256-999 will not give a response. Reading addresses 32-255 is known to work, though it's possible there are more valid ranges further out in the address space.

Holding Registers

Attempting to read addresses 0-330 doesn't work, but more of the address space will need to be explored.

Attempting to write addresses 0-140 doesn't work, but more of the address space will need to be explored.

Input Registers

Attempting to read addresses 0-140 doesn't work, but more of the address space will need to be explored.
