Selecting Input and Output Assemblies

The VSM500 unit uses Assembly Objects to send data to and from a scanner over an
I/O connection. The terms

input and output are defined from the scanner’s point of

view. An output assembly is the information that is

output by the scanner and

consumed by the VSM500 unit. An input assembly is the status data that is sent by the
VSM500 unit and consumed as

input by the scanner. Refer to Chapter 5 for a

discussion on control I/O and assemblies.

DeviceNet parameters 107 [

OUTPUT

ASSEMBLY

] and 108 [

INPUT

ASSEMBLY

] must be

set with the output or input assembly for your system.

Step 1. In the Device Configuration - Enhanced Mode dialog box (see figure 3.8),

double-click parameter 107 [

OUTPUT

ASSEMBLY

]. The Device Configuration -

Modify Numeric Parameter dialog box appears.

Step 2. Select the desired assembly number, and then click Save to Device. Refer to

the Parameter List in Appendix B for a list of values.

Step 3. Click OK to close the dialog box.

Step 4. Repeat steps 1 through 3 for parameter 108 [

INPUT

ASSEMBLY

].

Enabling Network Control

In order for a scanner to control the VSM500 unit (e.g., start or stop), the VSM500 unit
must be configured to accept commands from the network.

Important: The drive requires a stop input at the control terminal bock, regardless of

the setting of parameter 34 [

START

SOURCE

].

Step 1. In the Device Configuration - Enhanced Mode dialog box (see figure 3.8),

double-click parameter 34 [

START

SOURCE

]. The Device Configuration -

Modify Enumerated Parameter dialog box appears.

ATTENTION: Changing the source of control may cause unpredictable
network conditions, resulting in equipment damage, injury, or death.
Ensure that you understand how a change affects your application.
Failure to observe these precautions could result in severe bodily injury
or loss of life.
