Technical Reference Manual, General
REM 54_
The REM 543 and REM 545 machine terminals differ from each other as to the
number of digital inputs and outputs as follows:
7.2. Hardware versions of REM 543 and REM 545
For the number of digital inputs and outputs of the machine terminals, refer to
section “Order number”. The number of matching transformers, sensor inputs and
analog inputs and outputs, and the auxiliary voltage range vary between the different
hardware versions of REM 54_. Moreover, both REM 543 and REM 545 can be
supplied with an RTD/analog module. For more detailed information about the
hardware of the machine terminals, refer to section “Hardware versions” on page 13.
7.3. Software configuration
Each machine terminal allows different software configurations based on separate
functions (refer to section “Functions of the machine terminal” on page 27).
Functions included in the selected functionality level (refer to section “Ordering
Information” on page 95) can be activated within the scope of the I/O connections
and considering the total CPU load of the functions.
