Features

• Interface doubling for PG connection to a SIMATIC S5
• Compatible
  with all S5 controllers including CPU 945. Since physical connection,
  pin allocation, and the electrical data conform to the PG/PLC
  interfaces, you can use your regular cables to connect the devices
  without having to bother with adapters
• When two PGs are connected to one PLC, all PG functions except "process command" can be executed simultaneously on both PGs
