    Application Precautions WARNING Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so may result in malfunction, fire, or electric shock. Operating Environment Precautions Caution Do not operate the control system in the following locations: Caution Take appropriate and sufficient countermeasures when installing systems in the following locations:...
  • Page 10 Application Precautions Caution Failure to abide by the following precautions could lead to faulty operation of the Link Adapters or the system, or could damage the Link Adapters or the system. Always heed these precautions. Observe the following precautions when using the Link Adapter system. Tighten the screws on the terminal block of the AC Power Supply Unit to the torque specified in the operation manual.

  • Page 11: Introduction

    This document is designed to introduce the reader to the principles of Link Adapters and Repeater Units. Link Adapters and Repeater Units are connecting devices for SYSMAC C-Series Programmable Controllers. Link Adapters are used to interconnect system devices such as host computers, PC Link Units, Host Link Units, and Remote I/O Units, and/or to convert back and forth between wire cable and optical fiber cable.

  • Page 12: Nomenclature

    Link Adapters Nomenclature Names of specific OMRON products, as well as generic names for groups of OMRON products, are capitalized in this manual. Unit is also capitalized when it refers either specifically or generically to an OMRON product. For convenience, prefixes are omitted from model numbers of Link Adapters and Repeater Units.

    RS-422 and RS-232C Cable Power Supply and Cable Lengths Power Supply For all but AL001 Link Adapters, connect the AC hot line to the common terminal of the Link Adapter. A fuse is internally connected to the common line. Cable Lengths Maximum length for RS-232C cable is 15 m.
  • Page 17 RS-422 and RS-232C Cable Connecting Link Adapter When using a Link Adapter, connect both RS-232C and RS-422 cable straight AL004-(P)E across, as shown in the following diagram. Here the SD terminal of the host com- puter, for example, is connected to the SD terminal of the Link Adapter. See 5-4 Link Adapter AL004-(P)E for the internal configuration of the Link Adapter.

  • Page 18: Optical Fiber Cable (Apf/Pcf)

    All OMRON PCF and the PF10l APF (length: 1 m) cables come with con- nectors attached. Connectors for all other APF cables must be assembled by the customer.

  • Page 19: Crystal Optical Fiber Cable (Agf)

    Crystal Optical Fiber Cable (AGF) Crystal Optical Fiber Cable (AGF) Link Adapters AL005-(P)E and AL006-(P)E can be connected with crystal opti- cal fiber cable in accordance with the following specifications: The transmission distance between Link Adapters AL005-(P)E and AL006-(P)E is basically determined by the difference between the transmitting and receiving levels of the Link Adapters and by the transmission loss over the crystal optical fiber cable.

  • Page 20: Backup Power Supply

    Backup Power Supply When total transmission loss from the system is subtracted from the transmit/re- ceive differential of the Link Adapters, the margin must be at least 4 dB. To deter- mine total transmission loss, first calculate the loss over the cable by multiplying the loss/km by the total length of the cable.
  • Page 21 Section Backup Power Supply The following diagram illustrates a situation in which a 12V battery is used as a backup power supply, connected to the Link Adapter in Plant B. If there were no backup power supply in this case, then a power failure in Plant B would cut off signal transmission between Plant A and Plant C.

  • Page 22: Link Adapter Repeater Input

    Link Adapter Repeater Input Link Adapter Repeater Input Link Adapters AL002-(P)E and AL006-(P)E have repeater input terminals. They are used when it is necessary to be sure that power has already been turned on in a system connected to a branch line of the Link Adapter before signals are transmitted along the main line.
