• Analog value comparator/threshold controller (only
with easy800 V DC variants)
• Arithmetic,
– addition, subtraction, multiplication, division
• Compare data blocks
• Transfer data blocks
•Boolean sequence
• Counters,
– up and down counters with upper and lower threshold
values, preset
– frequency counters,
– high-speed counters,
– Incremental encoder counter
• Comparators
• Text, output freely editable texts, enter values
• Data function block
• PID controllers
• Smoothing filters
• Value scaling
•Pulse width modulator
• Read (GET) data from the easy-NET
•Time switches,
– weekday/time
– year, month, day (date),
• Numerical converters
• Master reset
• Operating hours counter
• Write (PUT) data to the easy-NET
• Synchronisation of date and time via the easy-NET
