Page 117: Integration Of The Les 36
11.1 General information The LES 36/PB and the LES 36HI/PB are designed as a PROFIBUS DP/DPV1 compatible slave. The input/output functionality of the sensor is defined by the corresponding GSD file. The baud rate of the data to be transmitted is max. 6MBit/s under production conditions. -
Page 118: Profibus Address Assignment
PROFIBUS (slave address 126) is preset. Automatic address assignment The LES 36…/PB supports automatic detection of the baud rate and automatic address assignment via the PROFIBUS. The address of the PROFIBUS participant can be set automatically by the commissioning tool of the PROFIBUS system (a class 2 PROFIBUS master). -
Page 119: General Information About The Gsd File
Outputs (O) described are outputs of the control. Parameters (P) described are parameters of the GSD file in the control. Note! The current version of the GSD file LEUZE403.GSD for the LES 36…/PB can be found on the Leuze website www.leuze.com. Leuze electronic... -
Page 120: Overview Of The Gsd Modules
The LES 36…/PB has one module slot. Select the corresponding module from the GSD to set the process data of the LES 36…/PB that are to be transmitted. Several modules are available for selection. Beginning with the simplest input module M1, additional inputs are included with the subsequent modules. -
