Overview The display system is an electronic display and operating
device as well as a logic relay with the following:
• Logic frunctions,
• Timing relay and counter functions,
• Time switch functions,
• Arithmetic functions,
• PID controllers,
• Operator and display functions.
The display system is a control and input device rolled into
one. The display system allows you to implement many
different tasks in domestic applications as well as in machine
building and plant construction. The display system is a
modular and flexible device.
The integrated CL-NET network allows up to eight CL-NET
stations to be connected to a controller. Each CL-NET station
can contain a program. In this way, high speed control
systems with remote intelligence can be created.
In Terminal mode, the display system can be used to control
any device in the network and display data from it. The
display system makes its keypad and display available to the
other device for use.
Two display systems can be connected simply via the serial
interfaces.
Circuit diagrams are connected up using ladder diagrams,
and each element is entered directly via the display system
display. For example, you can:
• Connect N/O and N/C contacts in series and in parallel
• Connect output relays and markers,
• Define outputs as coils, impulse relays, rising or falling
edge-triggered relays or as latching relays,
• Select timing relays with different functions:
– On-delayed
– On-delayed with random switching,
– Off-delayed,
