V. Usage Tips (Installation / Wiring / Configuration / Maintenance)

Installation: Standard DIN rail or F3 rack backplane slot, push in the latch to lock; leave a gap for heat dissipation, keep away from strong electricity / frequency conversion interference.

Power Supply: 24VDC regulated power supply, positive and negative terminals; FG protective ground must be reliably grounded.

Communication:

Ethernet: Directly connect to the switch / PC, default IP 192.168.0.1, used for downloading / monitoring / configuration.

RS485: Connect according to A/B polarity, to the instrument / third-party serial port device.

Configuration (SILworX): New project selection F3313; configure IP, protocol, redundancy, interlock logic; compile and download, online monitoring.

Maintenance: Regularly check power supply, contact, wiring; check the panel lights + software diagnosis for faults; support hot swap replacement without downtime.
