Description
The basic unit, PM 802F and respectively PM803F, cyclically
scans signals from the fieldbus sensors via the corresponding
fieldbus modules, processes these signals according the appli
cation programs installed by the user and sends appropriate
signals to the fieldbus actuators via the fieldbus modules.
Controller redundancy can be achieved by installing two
AC 800F. To ensure quick and smooth takeover by the secon
dary AC 800F in case the primary AC 800F fails, a dedicated
redundancy communications link through the second Ethernet
module makes sure that both AC 800F are always synchro
nized. All inputs and outputs are designed to support redundant
operation.
Data communication between AC 800F, process and operator
stations runs over the Ethernet system bus on the first Ethernet
module. Data exchange with the engineering station is also car
ried via the system bus. Engineering station communications
can involve new or updated configuration files being
downloaded to the process stations, or information about the
connected modules being reported back. When fieldbus mod
ules are installed or exchanged, the required configuration in
formation is automatically updated.
Configuration and real-time process data is stored in RAM. To
safeguard this data in case of power loss, the RAM power is
backed up with batteries located either on the Ethernet modules
or on battery modules.
The PM 803F has more memory than the PM 802F and is
therefor capable to handle larger projects. Due to increased
memory size and different technology the buffering times were
reduced.
