This function makes it possible to read and write files sequentially.
The follwoing functions are supported by straton Runtime versions
CE
RT (PC)
RTK (PC)
and are implemented
:
F_ROPEN, F_WOPEN, F_AOPEN, F_CLOSE, F_EOF, FA_READ, FA_WRITE, FM_READ, FM_WRITE,
FB_READ, FB_WRITE, F_EXIST, F_GETSIZE, F_COPY, F_DELETE, F_RENAME, LogFileCSV
The follwoing functions are only supported by straton Runtime versions
CE
RT (PC)
and are implemented
:
F_EXIST, F_GETSIZE, F_COPY, F_DELETE, F_RENAME
The possible paths vary depending on the operation system (XP,Vista). Keep in mind that under
Windows Vista some directories are write-protected if the UAC (User Account Control) is activated.
The execution of the SFC program equals that of a T5 standard target system und follows the
information of the straton Workbench help.
The exclusiveness of transitions within a divergence is supported.
A maximum of 65535 Binding variables can be published in the network. However this value is reduced
by every variable which is sent to zenon using the event service.
The standard IP port number of a straton Runtime is 9000.

This feature is supported by all straton target systems (RT, CE, RTK). All C compilers which are normally
proposed by the straton Workbench can be used.
Only use the default name of the created
Runtime-DLL.

1: Driver which support the variable status bits are only emulated or not supported by the straton RTK.
Therefore no access is granted to the status bits or the time stamps.
The straton Runtime from COPA-DATA saves its RETAIN variables after every cycle if a value changed.
The place where data is stored can be varying. Normally the values of the RETAIN variable are saved in
the instances path (handover parameter PATH). Depending on the system, it can be the hard disk or a
flash card.
Some straton I/O drivers support saving the RETAIN values to the SRAM (battery buffered RAM), e.g.
the ThinkIO/System758 driver.
In order for the RETAIN values to be loaded when the PLC application is restarted, the straton Runtime
must be started with the corresponding handover parameters/settings (cold start - load RETAIN
variables).

You can find information about the support of Online Change or Hot Restart here:
