Operation
5Operation
During operation, you can access up-to-date measured values and diagnostic information for
the I/O modules via the com unit. For more information, refer to the software manual for the
com unit used.
In addition, you can read off basic information about supply and communication from the LEDs
on the I/O modules and com units. For more information about the LEDs, refer to the data
sheets for the I/O modules and com units used.
Danger!
Risk of explosion
If I/O modules are hot swapped, there is a risk of explosion due to sparks forming, since the
connections on the backplane are not intrinsically safe.
Before replacing I/O modules, make sure that the atmosphere is not potentially explosive, e.g.,
by obtaining a hot work permit.
