5.4.2 Configuring the JX2-PROFI1
After applying the power supply, the module delays, until a valid configuration via the
registers has been made.
If the JX2-PROFI module has been configured correctly, communication with the
PROFIBUS master will be processed automatically and independently from the user
program. The user will be able to read and write data, to send diagnose telegrams
and to monitor the status of the PROFIBUS via register.
Steps of configuration:
If the connection with the master has been established properly, the following actions
can be taken via the registers (see also Fig. 6: "Diagram: PPLC - PROFIBUS
communication via registers", 24):
Buffer configuration
After start-up and initializing, the buffer configuration may have to be
adjusted:
•
Write the respective values into registers 1m112 and 1m113
Number of input and output words
Now set the number of PROFIBUS input and output words:
•
Write the respective numbers into registers 1m102 and 1m103
After you have taken this following step, you will not be able to
change the module configuration any more!
Initialize the PROFIBUS interface by setting the PROFIBUS station
address
•
Write the desired station address into register 1m107.
If, for example, a new station address is entered now, an error
will be reported. Not before issuing a "reset“ command, you will
be enabled again to alter the width of the I/O data and to assign
a new station address.
Communication with the master
Check, whether communication has been established successfully:
•
Call up register 1m100.
There is a difference between correct initialization of the JX2-
PROFI module (bit 0 through 2) and established communication
with the PROFIBUS master (bit 3).
