Behaviour on start up
IOPS = bad
If the Input Output Provider Status (IOPS) associated with a sub module is BAD (any value other than
0x80), then the I/O data of that sub module as viewed over PROFINET® will be cleared to zeroes. The
equivalent parameters viewed on the TFT screen, or over the web interface, are not cleared. Upon
receiving a network message with IOPS=BAD, no parameters of the pump that were attempted to be
written will be updated, and the Network Status LED will flash once in green. The pump will continue
to respond normally however, to any valid future messages. By default, the motor will stop if
IOPS=BAD, but this behaviour can be customised using the
failsafe
settings.
Disconnection
If a PROFINET® connection is aborted (for example, the Ethernet cable is disconnected), then the I/O
data of all sub modules as viewed over PROFINET® are cleared to zeroes. The equivalent parameters
viewed on the TFT screen, or over the web interface, are not cleared. New connections may be
established without needing to reboot the pump. By default, the motor will stop upon losing
connection, but this behaviour can be customised using the
failsafe
settings.
Mains power on
The I/O data of all sub modules as viewed over PROFINET® will be cleared to zeroes. This does not
clear the parameters stored on the pump itself.
By default, the motor is stopped on power on, however this behaviour can be modified using the
Auto Restart
setting, and also the
Resume Interrupted
setting if in
Dispense
mode.
