Show HN: Pyhoff – Connect Python ML Models to Beckhoff/WAGO IO Hardware

Summary

Pyhoff Description The pyhoff package allows you to read and write the most common Beckhoff and WAGO bus terminals ("Busklemmen") using the Ethernet bus coupler ("Busskoppler") BK9000, BK9050, BK9100, or WAGO 750_352 over Ethernet TCP/IP based on ModBus TCP. Key Features Supports a wide range of Beckhoff and WAGO analog and digital bus terminals. Very lightweight: no dependencies; compact code base Easy to extend Using standardized ModBus TCP. Provides high-level abstractions for reading and writing data from/to IO-terminals with minimal code Usage Scenarios Industrial test setups. Research automation setups. Data acquisition and monitoring. Installation The package has no additional decencies. It can be installed with pip: pip install pyhoff Usage It is easy to use as the following example code shows: from pyhoff . devices import * # connect to the BK9050 by tcp/ip on default port 502 bk = BK9050 ( "172.16.17.1" ) # add all bus terminals connected to the bus coupler # in the order of the physical arrangement bk . add_bus_terminals ( KL2404 , KL2424 , KL9100 , KL1104 , KL3202 , KL3202 , KL4002 , KL9188 , KL3054 , KL3214 , KL4004 , KL9010 ) # Set 1. output of the first KL2404-type bus terminal to hi bk . select ( KL2404 , 0 ). write_coil ( 1 , True ) # read temperature from the 2. channel of the 2. KL3202-type # bus terminal t = bk . select ( KL3202 , 1 ). read_temperature ( 2 ) print ( f"t = { t :.1f } °C" ) # Set 1. output of the 1. KL4002-type bus terminal to 4.2 V bk . select ( KL4002 , 0 ). set_voltage ( 1 , 4.2 ) Contributing Other analog and digital IO terminals are easy to complement. Contributions are welcome!
