  • Page 10 PRECAUTIONS This section provides general precautions for using the Wired Remote I/O System and related devices. The information contained in this section is important for the safe and reliable application of the Wired Remote I/O System. You must read this section and understand the information contained before attempting to set up or operate the Wired Remote I/O System.

  • Page 11: Intended Audience

    It is extremely important that the Wired 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 Wired 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 12: 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 13 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 Wired Remote I/O System, or could damage the PC or PC Units. Always heed these precautions.
  • Page 14 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 1 Introduction This section introduces Wired I/O Systems and describes their characteristics. Remote I/O Systems ............Wired Remote I/O Systems .

  • Page 16: Remote I/O Systems

    Section 1-1 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 Re- mote 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 Ex- pansion I/O Racks connected directly to the CPU Rack.
  • Page 17 Section 1-1 Remote I/O Systems A Remote I/O System directly involves only one PC and the program in it and through it a large number of I/O points can be controlled a greater distance from 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.

  • Page 18: Wired Remote I/O Systems

    Section 1-2 Wired Remote I/O Systems A Master is mounted to the CPU Rack or an Expansion I/O Rack; a Slave is mounted to a Backplane to form what is called a Slave Rack. To a Slave Rack is mounted the same other Units as those mounted to the CPU or Ex- pansion I/O Rack, with only a few exceptions (e.g., Link Units other than Slaves cannot be mounted to Slave Racks).
  • Page 19 Section 1-2 Wired Remote I/O Systems The other basic type of Remote Terminal consists of two parts: a Remote Interface and an I/O Block. The Remote Interface functions to transmit input or output signals between the Remote I/O System and the I/O Block. I/O Blocks enable easy removal and replacement of individual relays, including relays with a large switching capacity, making them ideal for controlling large motors, heavy equipment, etc.

  • Page 20: System Design

    SECTION 2 System Design Although there are many possible Remote I/O Systems that can be built out of Masters, Slaves and Remote Terminals, each System is limited by the capacity of the PC and the nature of the other Units in the System. Section 2-1 describes System configurations based on the C500-RM201 Master and C500-RT201 Slave (i.e., for C120, C500, C1000H, and C2000H Systems), and outlines connection requirements, mounting restrictions, and System size limitations.

Note that a Master in a C120 System must be mounted to an I/O slot on a C500 Expansion I/O Rack.
  • Page 25 Section 2-1 Basic System 2-1-2 C500 Systems In C500 Systems, up to four Masters can be connected to the same PC, and up to two Slaves and 32 Remote Terminals can be connected to any one Master. C500 PCs provide 512 I/O points. This means that the total number of points used in the System must be 512 or less.
  • Page 26 Section 2-1 Basic System 2-1-3 C1000H and C2000H Systems In C1000H and C2000H Systems up to eight Masters can be connected to the same PC. In C1000H and C2000H Systems, up to eight Slaves and 32 Remote Terminals can be connected to any one Master. When a Remote I/O System is included, C1000H and C2000H PCs provide 2,048 I/O points.
