Verifying Correct Operation

The final step is to verify that the MVI69-PDPMV1 module is communicating with
the PROFIBUS slave. Choose the method that best suits your connection and
proximity to the modules and the processor.
 If you are able to view the module directly: Look at the PROFIBUS LEDs on

the MVI69-PDPMV1 (page 134)

 If you are able to connect to the module using ProSoft Configuration Builder

and a serial cable: View the Fieldbus Data from the MVI69-PDPMV1’s
Configuration/Debug menu

 If you are able to connect to the processor using RSLogix 5000: View the

Controller Tags in RSLogix 5000

 If you are able to connect to the processor using RSLogix 5000: Send a

Mailbox Message in RSLogix 5000

5.1.1 Checking the PROFIBUS LEDs on the MVI69-PDPMV1

 If all four PROFIBUS LEDs are illuminated green, then the PROFIBUS

Master is communicating and exchanging data with all configured PROFIBUS
slaves.

 If the COM STAT LED is green and flashing, the PROFIBUS Master is

communicating and exchanging data with at least one of the configured
slaves.

 If the COM STAT LED is red, there is a communication or configuration error.
 If the COM STAT LED is off, the PROFIBUS Master is not communicating

with any slaves. The most likely reason is that the slaves are not correctly
configured.

 After restarting the MVI69-PDPMV1 Master and the PROFIBUS slave, look at

the PROFIBUS cable connection. If all the PROFIBUS LEDs on the MVI69-
PDPMV1 are illuminated green, then the Master is communicating
successfully with all slaves.
