PMX
Depending on how many sub-parameter sets are
switched, the switching time takes between 0.1 and
2.5 seconds.
S
Can the PMX also be used as a fieldbus master?
PMX can only be used as a master in the Ethernet-
based fieldbuses (EtherCAT, PROFINET and
EtherNet/IP).
If the CANopen interface is used under CODESYS
Soft-PLC, the PMX can be run either as a CAN master
or CAN slave.
S
What happens if the supply voltage fails during the
saving of a parameter set?
This will destroy the parameter set and the PMX will
boot up with the factory setting after being switched
back on again. To avoid this, backing up the device
settings to PC is urgently recommended.
S
What happens if the supply voltage fails during a
firmware update?
The device either comes online again with the old
firmware after being switched on or the device loads
and installs the new/loaded firmware and is then
ready for operation after approx. 10-15 minutes.
S
What happens with a CODESYS application after a
power failure?
If the CODESYS project was saved as a "boot pro­
ject," the application will automatically start running
again after the PMX is turned on.
S
Can the source code of a CODESYS project be re­
loaded from the PMX?
No, because the compilation generates machine
code, which is loaded into the PMX. This ensures
knowhow protection.
However, when a program is created, the original
source code can also be transferred to the PMX and
