About device initialization

About this topic When working in device diagnostics software, you are often required to

initialize the device. This topic explains why device initialization is

necessary.

Opening

communications

Initializing a device opens communications with it. For example, if the

device is connected with a serial cable, the COM port is opened, and if

the device is connected with an Ethernet cable, the TCP/IP socket is

connected.

Homing motors Initializing a device homes motors that do not track their position along

their line of travel. Homing a motor moves it until it triggers an event,

called a home flag. This tells the motor its location.

The motors on some devices automatically move to their home

ositions when the device is turned on. The motors on other devices

must be initialized to be homed.

Setting profile

parameters

Initializing a device applies relevant parameters set in the device’s

profile.

Setting state and

memory variables

Most devices store variables in software or firmware. Initializing a device

sets these variables to their initial values.
