    !WARNING It is extremely important that a PLC and all PLC Units be used for the speci- fied 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 a PLC System to the above-mentioned appli- cations.
  • Page 17 !Caution Confirm safety before transferring data files stored in the file memory (Mem- ory Card or EM file memory) to the I/O area (CIO) of the CPU Unit using a peripheral tool. Otherwise, the devices connected to the output unit may mal- function regardless of the operation mode of the CPU Unit.

    PLC to which is mounted a non-insulated Unit (CS1W-CLK12/52(-V1) or CS1W-ETN01) connected to an external power supply. A short-circuit will be created if the 24 V side of the external power supply is grounded and the 0 V side of the peripheral device is grounded. When connecting a peripheral device to this type of PLC, either ground the 0 V side of the external power supply or do not ground the external power supply at all.

  • Page 19: Application Precautions

    Always heed these precautions. Failure to abide by the following precautions could lead to serious or possibly fatal injury. • Always connect to a class-3 ground (to 100 Ω or less) when installing the Units. Not connecting to a class-3 ground may result in electric shock.

    FINS commands have the following features: 1,2,3... 1. They are defined in the application level and do not depend on lower levels (i.e., the physical and data link levels). This allows them to be used across a variety of networks and CPU buses. Specifically, they can be used with Ethernet, Controller Link, and Host Link networks, and between CPU Units and CPU Bus Units.

    Host Link FINS Protocol Conversion and Use of Network Routing tables are required to enable the serial communications path to be treated as a network. This is because with Host Link FINS, the FINS remote node address is used to specify the target (communications partner PC that is the Host Link slave).

    Example: If the CompoWay/F command MRC SRC is “01” “02” (where the quotation marks (“ ”) indicate ASCII characters), 0, 1, 0, 2 must be treated as ASCII characters. Therefore, set “01” as 3031 hex (not 01 hex), and “02” as 3032 hex (not 02 hex).
