Integrating the LES in the process control
108
Technical description LES
Leuze electronic
When used with parameter ID 0x07D8, sensor control command 0x0059 can be used to
extend the transmission pause between the Z- and X-data packets from 0.1ms (factory
setting) to up to 1ms (useful in applications with controls with slow, small Ethernet receive
buffer).
When using sensor control command 0x0059 with parameter ID 0x07D8, three words of
user data are transmitted to the sensor:
If SF=0, the duration of the transmission pause is changed only temporarily.
If SF=1, the duration of the transmission pause is retained even following a restart of the LES.
Notice!
If the transfer of X-coordinates is switched off in measure mode, no visualization of
measurement data can be performed in the 2D- and 3D-views in LESsoft.
Set Single User Parameter (beginning with firmware V01.40!)
When using parameter ID 0x07DB, sensor control command 0x0059 can be used to activate
a median filter for the Z-coordinates. By activating the median filter, the Z-coordinates of
the measurement values are smoothed out, while occurring edges are retained. If the median
filter is activated, small interferences and structures can be suppressed.
When using sensor control command 0x0059 with parameter ID 0x07DB, three words of
user data are transmitted to the sensor:
Get Single User parameter (beginning with firmware V01.20 !)
When using parameter ID 0x07D4, sensor control command 0x005B can be used to check
whether X-coordinates are output.
Command syntax:
When using sensor control command 0x005B with parameter ID 0x07D4, one word of user
data is transmitted to the sensor:
