    Label Description Rotary switch GRT1-ML2 overview Communication dipswitches The GRT1-ML2 SmartSlice Communication Unit controls data exchange 1.1.1 Unit dipswitches between a TJ1-MC__ Motion Controller Unit (via a connected TJ1-ML__ MECHATROLINK-II Master Unit) and SmartSlice I/O Units over a MECHATROLINK-II network. For more information on SmartSlice I/O Units, refer to the GRT1 Series SmartSlice I/O Units Operation Manual (W455).

    End Units and end plates. • Install the GRT1-ML2 and the SmartSlice I/O Units on a DIN rail. To install a GRT1-ML2 on the DIN rail, press it onto the DIN track from the 1.3.2 Wiring front, and press the unit firmly until it clicks. Check that all DIN rail sliders of the unit are locked onto the DIN rail.
  • Page 9 To supply power to the units and the I/O devices, connect the power supply wires to the power supply terminals of the GRT1-ML2. If the wire ends have pin terminals, just insert the pin terminals in the power supply terminals.

  • Page 11: Setup And Usage

    The I/O data from GRT1-ML2 units is mapped in the TJ1-MC__ in order of the GRT1-ML2 addresses. For example, the I/O data of a GRT1-ML2 unit with address 67 hex is mapped before the I/O data of a GRT1-ML2 unit with Analog Inputs Analog Ouputs address 68 hex.
