PROFIBUS Slave Error and Status Data
The PROFIBUS Slave Error and Status Data area is discussed in this section. This
information is available in the PDPS status data file, and found in the diagnostic
PROFIBUS SLAVE STATUS screen. See Diagnostics and Troubleshooting (page 23)
for more information.
The data area is initialized with zeros whenever the module is initialized. This occurs
during a cold-start (power-on) or a warm-boot operation. Counter values are also
initialized to 0 at power up.
