Your server located at localhost:3000

Modbus device is anywhere. Suppose 192.168.1.1:502

Request design:

Template:

http://localhost:3000/{reg type}/{var type}/{reg addr(int)})/{value(write)}/{ip}/{port}/{slave id}

Example read:

http://localhost:3000/discrete_inputs/int/21/192_168_1_1/502/1

Example write:

http://localhost:3000/coil/int/22/1/192_168_1_1/502/1

Writing data from their reading differs presence parameter {val}

IP address with _ instead .

If value contains(float) . value writes with _ instead . too

Example:

http://localhost:3000/multiple_registers/float/7,8/33_5/192_168_1_1/502/1

Coil¶ ↑

Template:

http://localhost:3000/coil/int/address/ip/port/slave id

Example:

http://localhost:3000/coil/int/22/192_168_1_1/502/1

Discrete inputs¶ ↑

Template:

http://localhost:3000/discrete_inputs/int/address/ip/port/slave id

Example:

http://localhost:3000/discrete_inputs/int/21,22/192_168_1_1/502/1

Holding registers¶ ↑

Example:

http://localhost:3000/holding_registers/int/22/192_168_1_1/502/1

Input registers¶ ↑

Template:

http://localhost:3000/input_registers/float/address/ip/port/slave id

Example:
