The result is that with an input value of, for example, 100°C (212 °F), a value of 50% is output via
the OUT parameter.

Description
Static Revision No. read A block operates static parameters (Static attribute) that
are not changed by the process.
Static parameters, whose values change during optimiza-
tion or configuration, cause the ST REV parameter to
increment by 1.
This supports parameter version management.
If several parameters change within the shortest possible
time, e. g. due to loading of parameters from FieldCare,
PDM, etc. in the device, the static revision counter can
show a higher value.
This counter can never be reset and is not reset to a
default value after a device reset. It the counter overflows,
(16 bit), it starts again at 1.
TAG read/
write
Entry of user-specific text of max. 32 characters for
unique identification and assignment of the block.
User input:
Text with 32 characters maximum, options: A-Z, 0-9, +,
–, punctuation marks
Factory settings:
"– – – – – – – –" no text
Target Mode read/
write
For selecting the required operating mode.
Options:
0x08 AUTO
0x10 MAN
0x80 OOS
Factory settings:
AUTO
BLOCK MODE General information on the Block Mode parameter group
This parameter group contains three elements:
• the block's current operating mode (Actual Mode)
• the modes supported by the block (Permitted Mode)
• normal operating mode (Normal Mode)
A distinction is made between "Automatic operation" (AUTO), manual
intervention by the user (MAN) and "Out of service" (O/S) mode.
Generally, you can select from several operating modes in a function
block, while other block types only operate in the AUTO operating
mode for example.
