Operation Using Host Command Language Strings
Table 4-3 shows an example of the use of command strings from the host interface to the CLV. If using a host device with com-
mand strings, refer to the CLV Command Language Guide (a SICK Optic-Electronic publication) for information regarding other
command strings.
Similar to the menu-assisted approach, all parameters (except data format of the host interface) can be customized as described.
With a host device, for example, the user can program each reading station of a conveyor installation individually, and reinitialize
them following start-up.
