The False/True constants are provided primarily to be used with the logic block. The variable
constants are also useful with the logic or math blocks.
Fault Detection Objects
Object 5040h
FD Field Value
is a read only object containing the field values of the over
temperature, over and under voltage. Object 5041h
FD Set Threshold
sets the limit values for
which the faults occur when reached. When any of these thresholds are reached, the faults will
clear when the values have lowered to values set in object 5042h
FD Clear Threshold.
For the 2IN-2OUT-SIG-CO controller to begin monitoring fault detections, object 5050h
Error
Check Detection
determines which Fault Detection is enabled through 1 byte data as bits. Once a
fault is detected, object 5051h
Error Response Delay
will determine how long the fault needs to
be present to flag and error.
Automatic Update of Objects
Object 5550h
Enable Automatic Updates
allows for the controller to automatically update the
objects related to the input to defaults when it is changed. By default, this object is set to TRUE, in
which case the objects are set to their default values depending on the type selected.
On the other hand, when this object is FALSE, the objects are not set to defaults and are left with
the same values previous to changing the type. In this case, these are to be configured manually.
Startup
The last object 5555h
Start in Operational
is provided as a
‘cheat’ when the unit is not intended to
work with a CANopen network (i.e. a stand-alone control), or is working on a network comprised
solely as slaves so the OPERATION command will never be received from a master. By default,
this object is disabled (FALSE).
When using the 2IN-2OUT-SIG-CO as a stand-alone controller where 5555h is set to TRUE, it is
recommended to disable all TPDOs (set the Event Timer to zero) so that it does not run with a
continuous CAN error when not connected to a bus.
