MELSEC-Q Series Sequencer CC-Link System Master / Local Unit

Caution
Product Description
· Cost-effective field network with broad device compatibility.
· Supports high-speed data transfer for both bit data (ON/OFF status) and word data.
· Ensures consistent cyclic transmission by separating it from message communication, preventing delays even during high message traffic.
· Compatible with CC-Link versions 1 and 2.
· Can function as either a local or master module, providing flexible network configuration.
· Ideal for maintaining punctual link scan times, unaffected by message saturation.
