•
Serial bus - Add up to 128 serial bus channels to the serial bus connection on
the base processor layer. For more information on the serial bus input, see
“Serial Bus” on page 89.
•
GPS - Add up to 128 GPS channels to an ELCOM or ELDIO GPS receiver. For
more information on the GPS receivers, see “EGPS-5HZ (Somat GPS
Receiver)” on page 96 or “EGPS-200 (Precision GPS Module)” on page 97.
•
Vehicle bus - Add up to 254 vehicle bus channels to a vehicle bus module (VBM)
compatible with an ELCOM or ELDIO layer. For more information on VBMs, see
“Vehicle Bus Module” on page 99.
6.6.1 Common Bus Channel Parameters
NOTE
All bus-oriented input channels for any given connector must have the same sample
rate.
NOTE
The connector parameter has no physical significance, but is a required parameter.
Enable Active Querying (serial and vehicle bus only)
Specify whether or not to use active querying.
Desired Rate (serial and vehicle bus only)
Set the query rate if active querying is in use. The limit on the query rate is a function
of multiple parameters including the type of bus and the amount of broadcast data
making it necessary to investigate this limit on a case-by-case basis.
Most active query requests are for packets that contain more that one bus channel. If
the active query rate is equal for a set of channels with the same request value, the
eDAQ
lite
ensures that the request is generated at the specified rate. If different query
rates are specified for the channels in the set, the eDAQ
lite
sets the actual query rate
as the maximum of the specified query rates.
NOTE
Use the active querying master control setting in the hardware configuration dialog to
disable or limit active querying.
NOTE
There is a limit to the amount of active querying which is a function of multiple
parameters including the type of bus and the amount of data broadcast on the bus. It
is recommended to investigate this limit on a case-by-case basis.
