* Not connected indicates “not electrically connected internally”. Not used indicates
“electrically connected internally, but serves no purpose”.
** Pin 14 and 15 are connected through to the piggyback board and are reserved for the
digital communication option in case the standard piggyback is installed. In case the
Profibus-DP piggyback is installed, these pins are not connected.
The minimum requirement to operate the device on a Profibus network is the
connection of the power supply lines, pin 5 (+15 Vdc to +28Vdc) and pin 9
(power supply common). For Profibus usage only +24V power supply option
is used (refer to the Installation and Operating Manual Smart TMF series,
doc. #541-C-051 and #541-C-061 for MF version).
The analogue output signals, representing a measure for the flow on pin 2
(voltage output), pin 4 (current output) and pin 10 (flow signal output common)
can be used in parallel with the network. Information on the flow can be
obtained through the network (in engineering units), but at the same time as a
voltage or current level through pin 2, 4 and 10. However, these pins can also
be set to OFF through the network, forcing them to the 0 volt/current level.
The setpoint command (Smart Mass Flow Controller models only), can be
issued either through the Profibus network or through an analogue signal
level. The user has to define the setpoint source and (in the case of an
