2 Device setup

We recommend performing the configuration steps in an office before mounting the device, especially if you are

not familiar with the DLS-A(H).

The DLS-A(H) supports two types of operation modes:

• Controlled mode

• Automatic mode

The first decision to be taken is the type of operation mode that will be used to transmit the distance

measurement data. While the controlled mode provides maximum flexibility and accuracy, it is often not suitable

for integration into existing PLCs or analog environments. In such cases the automatic mode might be preferred.

Key controlled mode automatic mode

(with analog output and digital outputs)

Accuracy Maximum measurement accuracy Accuracy depends on signal scaling

(see 8.3.5 Set distance range (sNv) on page 23)

Flexibility Access to full command set Limited

Integration Requires protocol implementation Wiring of AO and DO signals

Connection Connection of up to 10 DLS-A(H)s to a

single RS-422 line.

Point-to-point connection

The following two sections describe the configuration of the DLS-A(H) for the controlled and automatic modes.

2.1 Connection

To be able to configure the DLS-A(H), it must be powered and connected to a PC. Figure shows the necessary

connections. On the PC, any terminal program can be used to communicate with the module. Additionally, a

configuration utility is available on the web page www.dimetix.com
