INPUT/OUTPUT EXTENSION MODULE DEVICE OF DEVICENET

摘要

The present design is that, having a 2-bit identification address for identifying the master module and the slave module for generating and outputting an identification control signal of the communication permission signal, and the slave modules, respectively outputted from the master module according to the input and output expansion module of the DeviceNet device activated by the identification control signal of the communication permission signal, and the slave modules in the communication enable signal received received respectively received which is the first slave module for generating a control input and output tags and identify the next slave module control signal by the slave module identification control signal and , has a 2-bit identification address for identifying the slave module is received and accepted enable communication permission signal is outputted from the master module controls the input and output tags by the slave module identification control signal outputted from the first slave module, and identifying the next slave module control second generating and outputting a signal It is to increase the input and output tags of each module to the slave module consists of three and the fourth slave module to the same function as a slave module, and the second slave modules and reduce the manufacturing cost.
