  • Page 10 This manual has been prepared to explain how to incorporate Optical Remote I/O Systems into C120, C200H, C500, C1000H, and C2000H PC Systems. It provides the necessary information, such as system configuration, settings, and I/O word allocation, for connecting Remote I/O Master Units, Re- mote I/O Slave Units, I/O Link Units, and/or Optical I/O Units.
  • Page 11 PRECAUTIONS This section provides general precautions for using the Optical Remote I/O System and related devices. The information contained in this section is important for the safe and reliable application of the Optical Remote I/O System. You must read this section and understand the information contained before attempting to set up or operate the Optical Remote I/O System.

  • Page 12: Intended Audience

    It is extremely important that the Optical Remote I/O System be used for the specified purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying the Optical Remote I/O System to the above-mentioned applications. Safety Precautions WARNING Do not attempt to take any Unit apart while the power is being supplied.

  • Page 13: Operating Environment Precautions

    Application Precautions Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits. The PC will turn OFF all outputs when its self-diagnosis function detects any error or when a severe failure alarm (FALS) instruction is executed. As a coun- termeasure for such errors, external safety measures must be provided to en- sure safety in the system.
  • Page 14 Application Precautions Assembling the Units. Setting DIP switches or rotary switches. Connecting cables or wiring the system. Connecting or disconnecting the connectors. Caution Failure to abide by the following precautions could lead to faulty operation of the Optical Remote I/O System, or could damage the PC or PC Units. Always heed these precautions.
  • Page 15 Application Precautions Use crimp terminals for wiring. Do not connect bare stranded wires directly to terminals. Connection of bare stranded wires may result in burning. When replacing parts, be sure to confirm that the rating of a new part is correct. Not doing so may result in malfunction or burning.

    Section Remote I/O Systems Remote I/O Systems Assembly lines are often extremely long, making it difficult if not impossible to wire all I/O devices directly from CPU Racks or Expansion I/O Racks. A Remote I/O System can be used to solve this problem. In a Remote I/O System, a Rack can be located farther from the CPU Rack than is possible with Expansion I/O Racks connected directly to the CPU Rack.
  • Page 18 Section Remote I/O Systems the PC. This is achieved by mounting a Remote I/O Master Unit to the CPU Rack to control I/O points located possibly many kilometers away. Each Master serves as a ‘switching point’ for controlling all of the I/O points accessed through it.

    Remote I/O Units is that the Master be on one end of the System and I/O Link Units cannot be connected after C200H Slaves. There are three types of Master: One for the C120, one for the C500 (which is also used for the C120, C1000H, and C2000H), and one for the C200H. Two type of Slaves are available: One for the C500, C1000H, and C2000H, and one for the C200H.

  • Page 24: Multilevel Systems

    Section Multilevel Systems Multilevel Systems There is no reason that a Remote I/O System must remain restricted to one Mas- ter or to either wired or optical communications. PCs support multiple Masters, some of which can be Wired and some of which can be Optical. If there is more than one Master mounted under the control of a single CPU, each Master forms the beginning of a Remote I/O Subsystem.

  • Page 25: C20, P-Type, And K-Type Systems

    Up to four Masters can be connected to any one PC and up to two Slaves can be connected to any one Master. In C120 System, either C120 Masters or C500 Masters can be used. Which Master is used makes no difference to the opera- tion of the Remote I/O System.

  • Page 116 Appendix C Power Supply Wiring Precautions Voltage Drop If the wiring distance for the power supply to a Slave Rack in a SYSMAC BUS Remote I/O System is too long, there will be a voltage drop that may result in the power supply becoming insufficient for the Slave Rack load. Design the system so that a stable power supply can be provided for all Slave Racks.
  • Page 117 Appendix C Power Supply Wiring Precautions Power Supply Arrangement Supplying Power for I/O Altogether When designing systems where power is supplied for all I/O from the same power supply, it is necessary to con- sider the power consumption for each load and each Rack’s internal power consumption. Use cable sizes so that voltages for all loads and Racks in the system will stay within the allowable voltage variation ranges.
