Modbus whitelisting:

• Improve operational safety via the modbus protocol with intelligent firewall
• Secure data traffic and effectively isolate threats

Comparator:

• 125 comparators in 32 comparison groups
• Early warning if threshold values are exceeded and if discrepancies arise in consumption
• Avoid expensive downtime via overcurrent alarms and collective fault signals
• Reliable data transmission via OPC UA or modbus

Power quality:

• Avoid downtime and interruptions whilst improving operating efficiency
• Identify potential faults and protect systems from damage due to early detection of discrepancies in the measurement circuit
