Product Description
Operator Panels OP7 and OP17 allow operating states, current process values
and malfunctions of a connected PLC to be visualized. In addition, inputs can
be made on the OP which can be written directly to the PLC. Some functions
relating to machine diagnostics can also be executed on the Operator Panel.
The Operator Panels feature a number of standard functions. The displays
and operation of the devices can be optimized by the configurer to meet the
requirements of the process.
The Operator Panels are suitable for fitting into switching cabinets and con-
trol desks. A printer can be attached to the OP for logging processes during
automation operation.
1.1 Configuration and process control phases
Before an OP can go into service, it has to be prepared for its job of
visualizing data from the PLC, i.e. it has to be configured. As far as the PLC
is concerned, data areas used by the OP to communicate with the PLC have
to be created in the memory.
The configuration for the OP is created on a computer (PC/PU) using
ProTool configuration software under Microsoft
Windows TM . When the
configuration is ready, it is transferred to the OP. Before this can be done,
however, the computer has to be connected to the Operator Panel. Following
transfer of the configuration, the OP has to be connected to the PLC.
The OP now communicates with the PLC and reacts to program flows on the
PLC on the basis of the configured requirements.
figure 1-1 depicts the configuration and process control phases described
