2600-13 Press Control Module
MicroLogix 1500 & CompactLogix Resolver Module
Revision 2.1
Die Monitor Parameters
Each of the 2600-13 module’s inputs can be configured to verify that an expected condition occurred during
the press operation. Depending on how the 2600-13 has been configured, an unexpected event will cause
status bits to be set, fault output(s) to be activated, the input number where the first error occurred to be
captured, and a counter incremented to indicating the number of errors detected.
There are five types of Die Monitoring checks:
Normally True
. This is defined as the input being true over the entire turn of the resolver. The fault
will be detected and the count incremented immediately each time the input goes from true to false.
When in continuous count mode, the counter will increment every time the input transitions from true
to false. When in self resetting count mode, the counter will become one when the input is false, and
then be reset to zero when the input becomes true.
Normally False
. This is defined as the input being false over the entire turn of the resolver. The
fault will be detected and the count incremented immediately each time the input goes from false to
true. When in continuous count mode, the counter will increment every time the input transitions
from false to true. When in self resetting count mode, the counter will become one when the input is
true, and then be reset to zero when the input becomes false.
Cyclical Check
. This is defined as the input being true at least once inside the programmed range,
and false at least once outside of the programmed range. The fault will be detected and the count
incremented at the trailing edge of the window if the sensor is never ON within the window, or at the
leading edge of the window if the sensor is never OFF outside of the window. In self resetting mode,
the counter will be reset to zero if no errors are detected between two consecutive check window off
setpoints. In either counting mode, the counter will increment only once between two consecutive
check window off setpoints
The Cyclical check type begins checking immediately after the unit is programmed, even if machine
operations begin in the middle of the check window. An input pulse that had occurred in the window
before the unit was programmed will be ignored.
Constant Check
. This is defined as the input being True inside the entire programmed range, and
false at least once outside of the programmed range. The fault will be detected and the count
incremented immediately if the sensor is OFF at any point in the window, or at the leading edge of
the window if the sensor is never OFF outside of the window. In self resetting mode, the counter will
be reset to zero if no errors are detected between two consecutive check window off setpoints. In
either counting mode, the counter will increment only once between two consecutive check window
off setpoints
NOTE
: Clearing a Cyclical or Constant Check Die Fault outside of the window with the input on will
cause the fault condition to be met when the resolver position enters the check window.
Quick Check
. This is defined as being True at least once inside the programmed range and false
outside of the entire range. The fault will be detected and the count incremented immediately if the
sensor is ever ON at any point outside of the window, or at the trailing edge of the window if the
sensor is never ON inside the window. In self resetting mode, the counter will be reset to zero if no
errors are detected between two consecutive check window off setpoints. In either counting mode,
the counter will increment only once between two consecutive check window off setpoints
The Die Monitor Input Check programming includes up to four resolver position based On / Off check
windows. Depending on the checking type used, the expected input must be active at some point within
these windows.
