Manual
Version 1.1.0, valid from FW Version 02
Via the
[Common]
menu item, the following I/O parameters can be set:
Table 141: “Common” Menu Item
Parameter
Settings / Description
Temperature unit
With this parameter, you can set the desired
temperature unit.
0: Celsius
*)
The process value is output in
degrees Celsius (°C).
1: Fahrenheit
The process value is output in
degrees Fahrenheit (°F).
2: Kelvin
The process value is output in
Kelvin (K).
Siemens S5 format
With this parameter, status information for S5-FB250
can be represented in the lower three bits of the
process value (but only if the corresponding channel
diagnostics are enabled).
On
Bit 0 = overflow (set in the
event of measurement
overrange/underrange)
Bit 1 = error (set in the event
of overflow/underflow)
Bit 2 = always 0
Off
*)
Status indicators not displayed
Interference frequency
suppression
The input filter is used to suppress interfering mains
frequency signal components. The frequency
depends on the application location and can be set
with module-level granularity.
0: 10 Hz
The mains frequency is 10 Hz
1: 50 Hz
*)
The mains frequency is 50 Hz
(e.g., Europe)
2: 60 Hz
The mains frequency is 60 Hz
(e.g., North America)
3: 400 Hz
The mains frequency is
400 Hz (e.g., marine and
aerospace)
*)
Factory setting
The settings are transmitted to the I/O module using the
[Write]
button.
Be aware of process value resolution change!
Activating SIEMENS S5 format changes the process value resolution. Specific
information about resolutions is available in Section “Process Data” > “Overview
of Sensor Types.”
