Method for connecting a hardware module to a field bus

摘要

The method involves establishing data connection between a hardware module (14) and a field-bus (26) by a network module (12) connected to a field-bus. The hardware module is coupled to the network module. The communication software is read out from the memory (18) of the network module by the hardware module and communication software is provided for the communication of the hardware module with the field-bus. The communication software is stored in the hardware module to communicate over the field-bus. Independent claims are included for the following: (1) network module; and (2) modular system.
