Timestamp Latching
Software-configurable Input Filters
Sync to Master
These features are configurable through the Studio 5000 Logix Designer
software.
Primarily, the Sequence of Events Input module 1732E-IB8M8SOER is used to
interface to sensing devices and detect whether they are ON or OFF and to
timestamp ON and OFF transitions. The module converts ON/OFF signals
from user devices to appropriate logic level for use in the processor. Typical
input devices include:
•
Auxiliary contacts
•
Limit switches
When designing a system using this module, you must consider:
•
The voltage necessary for your application
•
Whether you need a solid state device
•
Current leakage
•
If your application should use sinking or sourcing wiring
The 1732E-IB8M8SOER input module operates in FIFO and Per Point modes:
•
FIFO – Each channel provides buffering of the timestamped input data
for every input transition. A minimum of ten buffers is provided for
every input channel (total twenty data buffers for every input to contain
both OFF to ON and ON to OFF transition). The stored data is utilized on
a first-in-first-out (FIFO) basis.
•
Per Point Mode – The module produces timestamps for up to 2 input
transitions per input, one for OFF to ON transitions and another for ON
to OFF transitions; these timestamps can occur simultaneously on
separate inputs.
