3 Commissioning and parameterizable
functions
The operating data of the measuring instrument must be set according to the
requirements of the current measuring task.
The cover of the terminal housing is closed after connecting the sensor and the
power supply. Then the power supply is switched on. On completing the prepara-
tions the measuring instrument starts operating after a warm-up time of about
3 seconds. The connection is now set up in a PA-device. The device must be
addressed under its PROFIBUS address. See the SIMATIC PDM help function for
setting of the address.
Make sure the device addresses are set before operating two or more field
devices on the bus. Every address may only be assigned once so that the
addresses are unique. An address range of 1 to 125 is possible in principle;
address 126 is set in the as-delivered state. Usually the lower addresses are
assigned to the masters in PROFIBUS systems. We therefore recommend you to
start with address 30 for the device address assignment. The addresses are
assigned with the SIMATIC PDM software via the bus. In this case a new device is
always connected to the bus and the new address set with the PC tool (node
baptism). Then the next device is connected to the bus and the procedure is
repeated.
We recommend you to note the address on the device with a smear-prof pen.
