Adjustment via bus with the Configuration Software ICP 100
:
The condition for adjusting address and baud rate via bus is that there must not be two sensor modules with the same
address on the bus. Otherwise the bus connection has to be disconnected or the distribution voltage has to be
interrupted for the duration of the adjustment with those sensor modules that have the same address as the module
that is to be newly adjusted. The sensor module that is to be newly adjusted does not have to be set to the same baud
rate as the PC by way of exception! Please note also our notice below!
The adjustment or modification of address and baud rate via bus is always carried out together with the loading of a
new sensor program by means of the
Configuration Software ICP 100. The download is carried out as described in the
short description for the
Configuration Software ICP 100. From the LEDs at the front of the sensor modules you can see
which sensor module is being newly adjusted at the moment. If the LED
ERR changes from "off" to "flash", a new
program is just being transmitted to the sensor module. The values are taken over as soon as the data transmission via
bus has been successfully completed.
Notice
: The address 0 is provided for the PC in case of a transmission via PROFIBUS. This address can therefore not be
assigned to the data logger.
Notice
: The address 127 is reserved for broadcast transmission in the PROFIBUS-protocol and may only be assigned
for these cases.
Adjusting via RS-232 interface with the configuration software:
The
Datalogger IDL 101 has as an additional to the RS-485 bus interface a RS-232 host interface. Configurations can
be programmed over the RS-232 interface as well as over the RS-485 interface with the help of the configurations
software ICP100.
