1.2 Overview of functions
What are ePS Network Services ?
The ePS Network Services support machine tool manufacturers and manufacturing
companies with maintenance and services. This is carried out using software
services that are available on a CNC control, S7 control, IPC or standard PC.
This requires both a control on the machine that complies with the specifications,
and Internet access.
The ePS Network Services include:
Remote access
Remote access to the control via a secure Internet infrastructure.
This service permits remote access to the control.
• Desktop control
• File transfer
• Chat
• Video ...
Control monitor services
Recording of events in a history and documentation of the current status of the
control at this point. This allows the status of the device to be analyzed and
compared with earlier states should a fault occur.
The current status of the machine is documented using the following events and
data:
• Alarms, PLC events, time intervals, combinations of machine signals
• Limit value violation and time delay violation from condition monitoring
• Series of measurements/tests and operating performance monitors
• Manual help request by the machine operator in the event of faults
• HMI action log, machine data, NC status data
• PLC trace, PLC data blocks
• Certain files (e.g. log files) of the control
Condition monitoring services
Measurement and documentation of the current machine status on the basis of
predefined, standardized tests and continuous recording of status characteristics
(traverse path, traverse time and traverse operations for one axis). The test
parameters can be defined centrally and configured with appropriate warning limits.
Using series of measurements, it is also possible to identify trends and apply them
as a basis for optimizing maintenance and service activities.
The machine operator can then carry out these predefined tests quickly and easily
and without additional test equipment.
