Analog outputs of the MX878B
The MX878B is a dedicated module designed for analog outputs and math
channels. In contrast to other modules, the MX878B has no analog sensor
inputs. Instead it receives data from other modules via the ”isochronous
IEEE1394b FireWire transfer”. The module then routes this data to an analog
output.
You need to connect all modules via IEEE1394b FireWire (or use a backplane)
for the MX878B to become operational! Please note the ”ISO” column in the
catman® channel configuration window. This column indicates if a channel pro
vides its data via the isochronous link (indicated by a symbol). Click the column
or use the column’s context menu to enable or disable isochronous transfer for
a channel.
Providing the data via isochronous transfer may use up significant computing
power on the module (in particular on the MX410B module and the MX460B
high-speed module). Do not activate the isochronous data transfer unless it is
actually needed!
MX878B signal generator
The MX878B has 8 signal generators. The signals (e.g. set profiles for control
ling uni- or multiaxial actuators) can be individually generated and assigned to
analog outputs.
The following signal forms are available (to be defined in an ASCII file):
constant, sine, rectangle, triangle
