Modbus Mapping

Note

The following register mappings are based on a single-module configuration. Actual mappings may differ based on the physical slot arrangement in your system.

Modbus Register Mapping

Channel	Modbus Input Status Register	Common Terminal	Access
CH1	10001	C1	Read-Only
CH2	10002	C1	Read-Only
CH3	10003	C1	Read-Only
CH4	10004	C1	Read-Only
CH5	10005	C1	Read-Only
CH6	10006	C1	Read-Only
CH7	10007	C1	Read-Only
CH8	10008	C1	Read-Only
CH9	10009	C2	Read-Only
CH10	10010	C2	Read-Only
CH11	10011	C2	Read-Only
CH12	10012	C2	Read-Only
CH13	10013	C2	Read-Only
CH14	10014	C2	Read-Only
CH15	10015	C2	Read-Only
CH16	10016	C2	Read-Only

Notes:

• There is a one-to-one mapping between channels and registers (e.g., CH1 → 10001, CH2 → 10002, etc.).

Example Usage

Note

The following examples assume that it is the only module connected. Actual mapping may vary depending on the configuration of the system.

Python

import time
from pyModbusTCP.client import ModbusClient
import struct

client_ip = '192.168.1.255'  # Replace with your device's IP
client = ModbusClient(host=client_ip, port=502, auto_open=True)

value = client.read_discrete_inputs(address = 0, count = 16) # Read all 16 inputs
print(value)

Arduino

#include <ArduinoModbus.h> // Include Modbus library

// Assume ModbusRTUClient is already initialized (e.g., ModbusRTUClient.begin(...))
int slaveId = 0x01;       // The ID of the Modbus slave device
int startAddress = 0;     // The starting address of the inputs
int numInputs = 16;         // The number of inputs to read (0-15)

enum modbusType {
    INPUT_STATUS,
    INPUT_REGISTER,
    HOLDING_REGISTER,
    COIL
};

void setup() {
    # Setup modbus client
}

void loop() {
    uint16_t inputs[numInputs];
    ModbusRTUClient.requestFrom(slaveId, INPUT_STATUS, startAddress, numInputs);
    for (int i = 0; i < numInputs; i++) {
        inputs[i] = ModbusRTUClient.read();
    }
    for (int i = 0; i < numInputs; i++) {
        Serial.println(inputs[i]);
    }
}

Note

The above code uses the ArduinoModbus library and is not a complete program.

Safety Precautions

• Do not add or remove modules while field power is applied.

• Ensure proper grounding and wire connections to prevent electrical hazards.

• Follow all local and national electrical codes.

• Maintain adequate ventilation to prevent overheating.
