diagnostic data, status information for the motor feeder at
the switchgear cabinet and the device-internal error protocol.
It also contains all the status LEDs that are present on the
basic unit and facilitates access to the system interface from
outside the switchgear cabinet. Its keys can be used to
control the motor and to navigate the display menu.
The operator panel with display can only be used in
combination with basic unit 2 (SIMOCODE pro V) from
version *E03* onwards.
Organization blocks form the interface between the CPU
operating system and the user program. The order that the
user program is processed in is specified in the organization
blocks.
SIMOCODE pro protects three-phase and AC motors
according to IEC 60947-4-1. The tripping class can be set to 8
different settings, ranging from Class 5 to Class 40.
The pause time is the specified time for the cooling response
of the motor when tripped under normal operating conditions
(not in the case of an overload trip). After this interval, the
thermal memory in SIMOCODE pro is deleted and a new cold
start is possible. This makes frequent start-ups possible
within a short period of time.
According to the standard EN ISO 13849-1 "a distinct level
specifying the capability of safety-relevant parts of a control to
execute a safety function under predictable conditions". Five
Performance Levels are specified (a to e) with defined ranges of
the probability of a dangerous failure per hour.
PL "e" corresponds to SIL 3 and is specified as the highest level.
The PC cable is used to connect the serial interface of the PC
to the system interface of a basic unit for device
parameterization.
Type of fixing screws and cross-tip screwdrivers.
Automation of continuous production processes.
Controls manufacturing processes e.g. in the chemical
processing or water industry.
