Communication with a control system

Digital inputs and outputs, as well as digital interfaces (EtherCAT
PROFINET) are available for linking the PMX to machine or system controls.
Both these cases access the same device functionality. The signals and
states listed in 11.2 ff below are available in real time via the interfaces.

11.1 Device description file

Physical properties are described in the device master data file (e.g. transmit-
ted/received bytes). This is needed to parameterize the master and create the
automation program.
The device description files are on the PMX system CD (included among the
items supplied) or can be downloaded from hbm.com −> Support−> Software
and firmware downloads.

11.2 Setting the fieldbus transmission rate

The fieldbus transmission rate can be set as follows:
Set the user level to Administrator in the top right panel.
In the Settings −> System −> Device −> System Options menu:
Set "Update Rate" to 9600 Hz, for example.
The fieldbus update rate follows this value up to the fieldbus-specific maxi-
mum.
Changes will take effect immediately.
To permanently save changes click on the disk symbol.
