Further input parameters

Input of process temperature
The process temperature can either be input using an external sensor or entered as a fixed
value using the remote control, see also Electric connections non Ex (Page 46) and General
(Page 111) .
Input of process pressure
The process pressure can either be input using an external sensor or entered as a fixed
value using the remote control, see also Electric connections non Ex (Page 46) and General
(Page 111).

PROFIBUS configuration for SITRANS SL

Information on the input and output range as well as the consistency of cyclically transmitted
data is defined in the device master data file (GSD file). Using the configuration package,
this information is checked by the device and declared valid. During projection phase the
data to be transmitted in cyclical operation will be determined. This enables an optimal
quantity of the data to be transmitted. In the Siemens control system, the GSD files of all
commonly used devices are already available. These GSD files are also available on the
Internet for a subsequent import.
6.3.1

Cyclic data transfer

Cyclic data transmission is used to transfer data necessary for process automation between
the control or automation system (class 1 master) and the SITRANS SL device.
Setting the PROFIBUS address
The PROFIBUS address is factory-set to 126. It can be changed by the user
● using LUI (see section Menu - Communication (Page 125))
● using the configuration tool LDSComm.
