Control systems with PLC's using Ethernet/IP, DeviceNet, Profibus, Profinet, or CANopen, can take advantage of wiring reduction and machine simplification. Turck BL67 Fieldbus protocols are supported by the world's largest PLC manufacturers: Rockwell Allen Bradley RSLogix, Siemens Step 7, Omron, Schneider, and Automation Direct. 

Parker-Turck BL67 Fieldbus has three major components: 

  1. Communication modules provide the interface between the PLC and field bus system
  2. Valve driver modules provide control for 32 solenoids on an Isys ISO or Isys Micro air valve manifold
  3. 24 VDC Digital input / output and a full range of analog input / output modules provide a connection between discrete field devices and the PLC.
