19 Data storage
Measured values and data from the calculated channels
and data present on the fieldbus or in CODESYS can be
stored with the PMX in different ways. Attention must be
paid to the data volume, the memory speed and the stor­
age location. The speed of data storage does not affect
the measurement and data rates of the PMX.
DAQ (Data Acquisition):
The Ethernet interface of the PMX with a connected PC
and DAQ software are suitable for storing large data
volumes (DAQ). The HBM software catmanEASY/AP is
available for this, as is the individual software that can be
created using the PMX driver in dotNET, LabView or DIA­
dem. Using an Ethernet network, values from up to 20
PMX devices can be stored here synchronized to the
measured values.
Monitoring:
For stand-alone monitoring applications, measured val­
ues can also be stored in the PMX device memory (1
GByte in size) or to a USB stick (max. size 32 GBytes).
Only values that have been acquired by the particular
PMX can be saved here. For this type of data storage,
you need the basic device WGX001 with a free
CODESYS program ("Measure and Save1.2.pro­
jectarchive") that is included on the system CD and in the
collection of examples at

The following table gives an overview of the possible
signals and maximum storage rates.
