Installation and Commissioning Manual
EventVals A 2-bit value to be used when updating the digital inputs when
matching an Event from the range EventStart to Event End.
That is, the event defined in the EventStart field gets the first
value and all subsequent events up to EventEnd get the
following values.
Example:
In case the settings for a digital input configuration for SPA
channel 31 are the following: EventStart = 0, Event End = 1,
EventVals = 0,1,0,0, then the events of the SPA slave device
will update the value of the digital input to the Profibus as
follows:
SPA event code
EventChannel Allows gateway to work with a device in which the parameter
channel and event channel are different.
In Use The In Use flag indicates if the parameter was found in the
connected SPA slavedevice during the initialization phase. In
the Template info Field the In Use flag is marked with number
1. A zero indicates that the parameter was not found. For details
see Section 4.7. In Use flags.
Priority check box By checking the Priority check box you can define that the
message should be polled more frequently than other messages.
This is indicated by the letter P (prioritized) after the signal
name in the Template info field. If the signal is not prioritized
the letter N (normal) can be seen in the Template info field. The
default is N. For details, see Section 5.4.8. Template info.
Digital inputs can be updated in two ways:
• By matching an event read by SPA L or B command to the corresponding events
defined in the digital input (EventStart to EventEnd).
• Polling values directly from SPA slave devices. These digital inputs should not
have any events defined in EventStart or EventEnd. If both of these fields are
zero, the digital input should be updated on a regular basis by polling the values
from the SPA slave device.
