Manual And Remote Operating Modes - Siemens SITOP PSU8600 Manual

MANUAL and REMOTE operating modes

When the device powers up in the MANUAL mode, the settings, which were made directly at
the device with the potentiometers and selector switches, apply. For an unchanged system
configuration, the outputs are activated with the last operating status before shutdown.
When the device powers up in the REMOTE mode, the configuration parameter set,
assigned to the device by the associated control, applies. For an unchanged system
configuration, the outputs are activated with the parameters and operating states saved in
the configuration.
Was the last operating state of an output before shutdown
● "Manual shutdown" (LED "ON/OFF/RST" of the output is lit yellow),
● "Automatic shutdown due to overload" (LED "ON/OFF/RST" of the output is lit red)
or
● "Ready for reset" (LED "ON/OFF/RST" of the output flashes red),
then these operating states are assumed again when the system starts.
In the REMOTE mode, the operating states and parameters of the outputs can be changed
in operation, controlled by the program.
Note
In the REMOTE mode, in some instances, extended special functions can be selected for all
outputs via the configuration, which are not available in the MANUAL mode. You will find
more information on this at Engineering and remote access (Page 117).
Note
In order to ensure that in the MANUAL and REMOTE modes, the device operates with the
required device settings and/or reference parameter sets, the modes should only be
switched over when the power supply system is in a no-voltage state.
The switchover is made at the selector switch (see operator controls) with the
designation "REN"
When delivered, DIP switch "REN" is in position "OFF" (MANUAL mode).
