3-6 Using Memory Cards
1. Memory Cards can be used with the PT. History files can be stored in Memory Cards as
CSV files. There are four different types of history file, as follows:
Alarm/event history: Stores alarm/event history data that has been registered by NS-Designer.
Data log: Stores trend data.
Operation log: Stores screen operation log data.
Error log: Stores error history data for when macros are executed.
The history data is normally saved in internal memory that is backed up in the PT, but
can also be saved in CSV file format. When history data is saved as a CSV file, it is
stored in the Memory Card.
The CSV files are saved into the log folder created in the Memory Card.
2.
The following data can be transferred to the Memory Card.
· System programs (the programs required to operate the PT, such as for communica-
tions and fonts)
· Screen data (data used in the PT display)
There are three methods for transferring data, as follows:
· Automatic download (Transfers data from the Memory Card to the PT.)
· Automatic upload (Transfers data from the PT to the Memory Card.)
· Manual transfer (Direction for data transfer is selected manually.)
Reference
There are four types of recommended Memory Cards, each of which has a different ca-
pacity.
Model Memory capacity Memory type
HMC-EF172 15 Mbytes
HMC-EF372 30 Mbytes
HMC-EF672 64 Mbytes
Flash memory
The Memory Card can be overwritten approximately 100,000 times.
When using the PC card socket in devices such as laptop computers, use the HMC-
AP001 Memory Card Adapter.
For details on transferring data with the computer (NS-Designer), refer to Section 10 Transfer-
ring Data to and from PTs in the NS-Designer Operation Manual.
