You can display the system resources currently in use for the NC and
HMI Embedded areas (utilization display).
The display is also available in the "Start-up" operating area.
The procedure is described in Chapter 9, Section entitled "Display and
Change System Resources".
Errors occurring in the communication between HMI Embedded and
NCK/PLC are recorded in a communication error log.
You can display this log by pressing the "Comm. Log." key.
The error log file is principally used by the control manufacturer
(Siemens) as a diagnostic tool for communication errors.
The communication error log file can be read out via the RS-232
interface in the "Services" operating area.
