  • Page 4: Overview

    3 / 48 Overview This product is an RS-232C / Ethernet interface module for measuring systems that can acquire multi-axis measurement data. Because this product shares a common data format with existing MG10/10A products, MG10/10A users can continue to use their programming environment with just a few settings changes. In addition, the product has a PLC link function.

    17 / 48 6.2.3 Reference Point When the reference point is not used After the power is turned on, the measuring state is established automatically. (Incremental operation) When the reference point is used After the power is turned on, the unit automatically enters the reference point signal input wait status. Once the reference point is passed, the reference point position changes to 0 or the measurement from the offset value.

  • Page 20: Hold

    19 / 48 6.2.7 Hold The MG80-SC has two types of hold functions: latch and pause. They cannot be used at the same time. Latch In the current value mode, this function holds output data and comparator output for that value. When latched, the current value will stop updating, so the peak value will also stop updating.

  • Page 21: Measurement Data Output

    20 / 48 6.2.8 Measurement Data Output The measurement data is output to RS-232C based on the timing of the RS trigger input or the internal periodic timer. It is not output during parameter setup. The timing of the measurement data output should take into account the RS-232C baud rate. If the next trigger occurs during the measurement data output, incorrect data may be output.

  • Page 23: Plc Link Function

    22 / 48 6.2.10 PLC Link Function The PLC link function allows the MG80-SC to read and write the PLC’s memory and allows the PLC to operate the MG80-SC and obtain measurement data without the need to prepare a communication program on the PLC side. In order for the MG80-SC to read and write the memory of the PLC, the PLC must support one of the following communication protocols.

  • Page 26 25 / 48 The preset comparator upper/lower limits are treated as a single data item for two PLC devices. When setting the data, use little endian format. In addition, the value to be set is a count value whose last digit conforms to the input resolution. For example, if the input resolution is 5 μm, the 1’s place corresponds to 1 μm and the values that can be set are multiples of 5.

  • Page 27: Settings

    26 / 48 Settings When Upgrading from the MG10/MG10A First, set the resolution and polarity for each counter module. There are two ways to configure the settings: by using the setting application for Windows PC or by using commands. Use whichever method is most convenient. Module Number Setting Use a screwdriver or other tool to align the direction of the arrow on the module number setting switch with the number to be set.
