5.1.2 Controlling event generation

There are various functions that can be used to control event generation. The bit pattern accepted by

these functions is as follows:

Bit Event

Reserved

1 Error

2 CAN 1 (CANOpen)

3 CAN 2 (Baldor CAN)

4 Stop switch

5 Fast position latch

6 Timer

7 Digital input

8 Comms event from PC to controller (PC updated comms location)

9 Comms event from controller to PC (controller updated comms location)

10 DPR event from PC to controller

11 DPR event from controller to PC

Reserved

13 Move buffer low

14 Axis idle

The user can read which events are currently active using the function getEventActive.

Any currently pending events can be cleared selectively using the functions getEventPending and

setEventPending. Clearing a set bit will clear the pending flag for that event. Passing a value of zero

will clear all pending interrupts.

Once a handler has been installed the event generation can be disabled by using the function

setEventDisable. Setting a bit will disable the generation of that type of event. Setting this to zero will

enable all events which have a handler installed.

The function getEventDisable will return a bit pattern of any currently disabled interrupts. By default all

digital inputs will generate events when they become active. These digital inputs can be masked so that

they do not generate events using the function setIMask. This accepts a bank number and a bit pattern

of inputs. Bit 0 corresponds to input 0; if the bit is set then the digital input will generate an event when it

becomes active.

The user can interrupt an embedded application using the function doDPREvent. This will interrupt the

controller and pass a 16-bit code to the DPR event handler on the controller.
