5.4.5 I/O Data Monitoring
This is the function to monitor I/O data of slaves. This can confirm whether the I/O of a
certain slave is correct. If “I/O Monitor…” item is selected from “Diagnostics,” then existing
data communication is stopped, and the monitor window pops up as below. If users enter
the output into the output data and click update button, then the value will be displayed
through slave. And then the values entered through current slave will be monitored
through the input data area. (Here the number of data available for I/O is 32 bytes
respectively.)

5.4.6 Disconnection Report
This function shows the number of frequency of connection errors for slaves under data
communication. If you select “Disconnection Report…”item from “Diagnostics,” then the
number of errors occurred are displayed in real time as shown below.

“R” means reserved station number from 124 to 126 address.
Although MAX. station number can use 127 (0~ 126) stations in the PROFIBUS standard,
Pnet module is able to use 123 stations. So “R” of 124~ 126 stations are meaning the areas
that are not used.
