SIMODRIVE POSMO A User Manual (POS1) – 08/2013 Edition
The hardware inputs/outputs are high active.
Rules for input terminals
– A hardware terminal has a higher priority than a PROFIBUS signal
If a terminal is parameterized as input, then this terminal comple-
tely assumes the function, i.e. a control signal, with the same
significance, received via PROFIBUS, is ignored.
Exceptions:
If a terminal is parameterized with a value 100, 101 or 102 (OFF
1, OFF 2, OFF 3 logically AND'ed with the terminal), then the
following applies:
The signals are only present if they are set from the terminal and
from the PROFIBUS–DP master (this is a safety function).
– If both input terminals are assigned the same function number,
then terminal 2 has priority.
Rules for output terminals
– Output signals are output via a terminal without influencing
PROFIBUS communications.
– Inversion:
The outputs can be inverted by adding 128 to the values speci-
fied in the function list.
Example:
The "reference point set" signal should be output inverted via
terminal 1.
––> parameter value = 74 + 128 = 202 (refer to Chapter 5.6.2)
––> set P31 to 202
––> a signal is set at the terminal if SIMODRIVE POSMO A is
not referenced.
Signaling the terminal state (from SW 1.4)
The actual state of the terminal can be displayed in the feedback
signal byte (RMB) by adding 256 to the value specified in the func-
tion list.
RMB.6 ––> state of terminal 1
RMB.7 ––> state of terminal 2
