Reaction to "comparison value reached".
Load the new comparison value into the ACCUs and
set the cascading counter.
4.6 Failure and Monitoring of the Supply Voltages
The S5-95F monitors the 24 V DC supply voltage for the onboard I/Os. You can evaluate the status
of these voltages in the diagnostic byte IB 35 (see section 15.8).
Supply Voltage for Onboard I/Os (40-Pin Connector)
We assume that you use the onboard I/Os and that the supply voltage is therefore connected. If
there is no supply voltage
at
one subunit or at both subunits
, the S5-95F responds with a fault
signal. The S5-95F initiates no further reaction.
If you wish to react to a load voltage failure on one or both subunits, you must evaluate IB 35 in
the user program.
Please note that I/O faults with the corresponding system reaction can also be signalled as a result
of a load voltage failure.
Supply Voltage for Counter and Interrupt Inputs (9-Pin Sub D Connector)
If there is no supply voltage for counter or interrupt inputs
at one subunit
, the S5-95F responds
with a fault signal. The S5-95F initiates no further reaction. If there is no voltage supply at both
subunits, no fault signal is given.
If you wish to react to a load voltage failure on one or both subunits, you must evaluate the
diagnostic byte IB35 in the user program.
Please note that I/O faults with the corresponding system reaction can also be signalled as a result
of a load voltage failure.
