The “Get–OV” FMS service is used by the FMS master to read the object
description of the ET 200U(DP Standard/FMS). The ET 200U(DP Standard/
FMS) supports both the short and the extended form of ”Get–OV” (OV =
Object list).
“Status” is used by the FMS master to read the status of the bus interface mo-
dule (logical status) and the operating state (physical status) of the
ET 200U(DP Standard/FMS).
The “Local–Detail” attribute is not supported by the ET 200U(DP Standard/
FMS).
“Read” can be used by the FMS master to read the objects assigned to the
ET 200U(DP Standard/FMS).
“Write” can be used by the FMS master to obtain write access to the objects
assigned to the ET 200U(DP Standard/FMS).
The “Event–Notification” FMS service is used by the ET 200U(DP Standard/
FMS) to transmit diagnostics messages to the FMS master. The diagnostics
data are sent in connection with the diagnostics event.
The “Event–Notification” FMS service is possible only in conjunction with
the link types MSZY_SI and MSAZ_SI. If these types of links are not set up,
the ET 200U(DP Standard/FMS) is not able to transfer diagnostics events to
the FMS master.
“Acknowledge–Event–Notification” can be used by the FMS master to ac-
knowledge receipt of a diagnostics message from the ET 200U(DP Standard/
FMS). An acknowledgement by the ET 200U(DP Standard/FMS) is not re-
quired.
“Alter–Event–Condition–Monitoring” can be used by the FMS master to ena-
ble or disable events, e.g. diagnostics messages via “Event–Notification”.
In the default setting, events are disabled for the ET 200U(DP Standard/
FMS).
