Searching for devices by address

Clicking the Searching for devices by address button triggers a search for devices with a short address (0…15). The results are shown in the dialog box (see image above). Devices without an address are not displayed.

The Device information field shows the address, the slave ID and the manufacturer code for the selected device.

Address type

The individual modes of addressing are described below. Note that not every command supports all addressing modes.
The following types of device addressing are available:

• Broadcast
  A broadcast always addresses all devices, irrespective of the address set at the device.
• Group addressing
  Each device that is to be controlled via group addressing must have an address from 0 to 15. Use the checkboxes to select the addresses of the devices to be accessed.

Example: The drives with addresses 1, 4, 7 and 12 are to be accessed

• Individual addressing
• by address
  Each SMI device can be assigned an address from 0 to 15. Since each address should only be assigned once, each SMI device can be addressed individually.
  The address is stored in the SMI device and must be correctly set again when exchanging the drive.
  This address is also occasionally called the slave address. The slave address must not be confused with the slave ID (see below).
• via slave ID
  The device manufacturers store a unique 32-bit number in each SMI device. The slave ID, also referred to as key ID, can be used for addressing a device.
  With some SMI devices the slave ID is printed on the name plate or is made visible by a label on the cable.
  Most read commands do not support addressing by Slave ID.
• Addressing by manufacturer code
  All devices from a manufacturer are always addressed by this addressing.
  SMI defines a manufacturer code for each manufacturer. The manufacturer code is permanently stored in the SMI device and cannot be changed. Often abbreviated as M-ID.
  With some SMI devices the manufacturer code is printed on the name plate or is made visible by a label on the cable.

Commands

• Up Step / Down Step
  Enables motor travel up / down by a specified angle.
  In the listbox below, angles between 2 and 510 degrees can be specified (default: 10). Since the SMI standard reduces the accuracy to a resolution of 2 degrees, the angles are specified in 2-degree steps.
• Up / Down
  enables motor movement to the upper / lower end position.
• Stop
  stops the motor operation.
• Read Pos
  Reads the current position from the drive. The position value is shown below the button as an absolute value and in percent.
• The value = 0 (0 %) corresponds to the upper end position
• The value = 65535 (100 %) corresponds to the lower end position.
• Drive Pos
  The drive travels to a specified position value. The position value is specified via the input fields, either as an absolute value or in percent.
• Drive Pos1 / Drive Pos2
  The drive travels to the fixed position Pos1 / Pos2 that is configured on the motor side.
• Read Pos1 / Read Pos2
  Reads the fixed position Pos1 / Pos2 that is configured on the motor side and shows it as an absolute value and in percent.
• The value = 0 (0 %) corresponds to the upper end position
• The value = 65535 (100 %) corresponds to the lower end position.
• Write Pos1 / Write Pos2
  The position value for the fixed position Pos1 / Pos2 is specified via the input fields, either as an absolute value or in percent.
