3.2.48 ESL - Events Sequence Logger
ESL function blocks, in firmware 1.30 and higher, can be
used on a one per loop basis to log events within the loop.
Each ESL input can be assigned a user tag (up to 8 ASCII
characters) that will be displayed when viewing the logged
events from the front panel. Events, once triggered by a
positive transition 0>1 input, will remain in the logger
until reset. Reset can be initiated either by setting input R
high (this input is edge sensitive and will reset the events
on the leading edge) or by entering configuration and
setting the parameter RESET to YES.
Events logged to the ESL function block can be viewed at
the operator faceplate by pressing the ACK pushbutton
when displaying the loop containing an ESL function
block having logged events. The alphanumeric display
will first step through any active alarms, status conditions
or errors and then all the logged events that occurred since
the last reset. The configured 8-character name will be
shown in the alphanumeric display and the order of
occurrence (ESL-1, ESL-2...) will appear in the numeric
display when stepping through the event log. Other events
such as alarms, status conditions, or errors can be similarly
viewed if logged to the ESL function block.
