Specifications for Leuze end devices

Serial interface and Command mode

The corresponding Leuze end device can be selected while configuring the fieldbus gateway

(see chapter 9 "Configuration").

The exact specifications for the individual Leuze end devices can be found in the following

sections and in the device description.

The corresponding serial command is sent to the Leuze end device in Command mode. To

send the corresponding command to the RS 232 device after activating the Command

mode in byte 0 (control bit 0.0), set the corresponding bit in byte 2.

The Leuze end device also responds to most commands by sending data, such as the bar

code contents, NoRead, device version, etc., back to the gateway. The answer is not eval-

uated by the gateway, but is instead passed on to the PLC.

For the BPS 8, BPS 300i and hand-held scanners, a number of specific features are to be

noted.

16.1

Standard setting, KONTURflex (S4 switch position 0)

This switch position can be used with almost all devices, since a data frame is transmitted

along with it if necessary. A 00h in the data range of the control is interpreted as the end of

a telegram/invalid, however.

The distance between two successive telegrams (without frame) must be more than 20ms

in this switch position, since there is otherwise no clear separation between them. If neces-

sary, the settings have to be adjusted on the device.

Leuze measuring sensors with RS 232 interface (such as a KONTURflex Quattro RS) do not

necessarily use a telegram frame, which is why these are also operated in switch position 0.

Notice!

The data frame is specified via the switch position.Only the data mode and the baud rate

can also be set via the GSD file.

In the factory setting, the S4 switch position is 0. Resetting the settings to these is possible

in S4 switch position F. The procedure for doing this is described in chapter 16.13.
