3-10 VSM500 DeviceNet Option Board
3.11 Setting the Idle Action
The idle action determines how the VSM500 unit and DeviceNet option board respond
when the scanner is placed in idle/program mode. By default, the VSM500 unit is sent
zero data. You can change these settings if your application requires it.
Step 1. In the Device Configuration - Enhanced Mode dialog box (see figure 3.8),
double-click parameter 110 [ DNET IDLE MODE ]. The Device Configuration -
Modify Boolean Parameter dialog box appears.
Step 2. Select the appropriate setting for your application, and then click Save to
Device.
Step 3. Click OK to close the dialog box.
3.12 Setting the COS (Change of State) Mask
If you are using COS data exchange, you need to set a mask. The mask determines
which bits in the network status can trigger an I/O message.
Step 1. In the Device Configuration - Enhanced Mode dialog box (see figure 3.8),
double-click parameter 112 [ CHANGE OF STATE ]. The Device Configuration -
Modify Bit Parameter dialog box appears.
!
ATTENTION: Parameter 110 [ DNET IDLE MODE ] determines the action
of the option and connected VSM500 unit if the scanner is placed in idle
mode. By default, this parameter sends zero data to the unit. You can
set this parameter so that the unit continues to run. Precautions should
be taken to ensure that the setting of this parameter does not create a
hazard. Failure to observe these precautions could result in bodily injury
or damage to equipment.

Setting Description
Zero Data The VSM500 unit is sent 0 for output data when the scanner is in
idle mode. This stops the VSM500 unit.
Hold Last State The VSM500 unit continues in its present state after the scanner is
in idle mode. This may not stop the VSM500 unit.
If this setting us used, another method of stopping the drive must
be available (via the Function Loss terminal or the Stop terminal).
