A method of determining a configuration state of an I/O module connected to a fieldbus controller is disclosed, the method comprising the steps of receiving from the I/O module a key ID, comparing thekey ID with at least one key ID stored on the fieldbus controller, and configuring the I/O module when the received key ID does not correspond to the at least one stored key ID stored. Further, a circuit for configuring a digital input of a fieldbus controller as either a PNP input or an NPN input is provided comprising a control circuit including a reference input, a first selection input, and acontrol output. The circuit also comprises a data circuit including a second selection input electrically connected to the control output, a data input electrically coupled to the digital input, anda data output. 公开了一种确定连接到现场总线控制器的I/O模块的配置状态的方法，方法包括以下步骤：从I/O模块接收密钥ID，将密钥ID与现场总线控制器上存储的至少一个密钥ID进行比对，以及在接收到的密钥ID未与存储的至少一个存储密钥ID相对应时配置I/O模块。另外，提供用于将现场总线控制器的数字输入端配置成PNP型输入端或NPN型输入端的电路，所述电路包括控制电路，所述控制电路包括基准输入端、第一选择输入端和控制输出端。所述电路还包括数
