modbus_wrapper
wrapper for pyModbusTCP accepting all Modbus numbers with Fatek support
read
List of different Modbus types can be provided in the input:
Reading Coils, Holding registers and Discrete input:
>> client = ModbusClient("10.0.57.30")
>> modbus_object_list = [20,20,30,31,32,33,33, 400800, 400801, 100300]
>> client read(modbus_list)
{'20': 'False', '30': 'False', '31': 'True', '32': 'True', '33': 'False', '400800': '0', '400801': '0', '100300': 'None'}For above example only 3 modbus function calls will be executed:
read_coils(19, 14)
read_holding_registers(799, 2)
read_discrete_inputs(299, 1)- All coils are read in one function call thanks to MaxReadSize and ReadMask parameters which can be configured in modbus object config file
client.read(modbus_list, max_read_size=1)For above example, 8 modbus functions will be executed:
read_coils(19, 1)
read_coils(29, 1)
read_coils(30, 1)
read_coils(31, 1)
read_coils(32, 1)
read_holding_registers(799, 1)
read_holding_registers(800, 1)
read_discrete_inputs(299, 1)read with range
read_modbus_objects
write
write_modbus_objects
