PLCs, Power Supplies & Others

This communication module bridges the F-Touch controller with various industrial networks. It integrates seamlessly into the Fuji Electric F-Touch series automation platform. The unit enables data exchange between the PLC and external devices efficiently. Users can connect drives, HMIs, and remote I/O stations through a single module.

Protocol Support and Network Compatibility

This module supports multiple industrial communication protocols for versatile connectivity. It handles Modbus RTU and Modbus TCP for standard device integration. The unit also supports Fuji Electric T-Link for remote I/O expansion. Users can configure the module for ASCII and binary data transmission modes. This protocol flexibility simplifies integration with existing automation infrastructure. Consequently, engineers can connect diverse equipment without additional converters.

RS-485 Serial Communication Capabilities

The FFU120B provides two independent RS-485 ports for serial network connectivity. Each port supports transmission speeds from 1,200 bps to 115,200 bps for flexible configuration. The module connects up to 32 slave devices on each RS-485 network. Maximum cable length reaches 1,200 m for distributed system layouts. The unit includes built-in termination resistors for signal integrity improvement. Additionally, the ports feature optical isolation for protection against electrical noise.

Ethernet Communication and Network Management

This module includes an Ethernet port for high-speed data exchange over TCP/IP networks. The port supports 10/100 Mbps transmission with auto-negotiation capabilities. Users can connect up to 64 devices on a single Ethernet network segment. The unit implements Modbus TCP protocol for standardized industrial communication. It also supports remote diagnostics and firmware updates over the network. This connectivity enables centralized monitoring and data acquisition from multiple locations.

Data Mapping and Configuration Flexibility

The module maps communication data directly to the PLC memory for seamless integration. Users configure protocol settings, baud rates, and node addresses through software. The unit stores configuration parameters in non-volatile memory for automatic loading. Each port operates independently with individual protocol and speed settings. This independent operation enables simultaneous communication with different device types. Furthermore, the module supports both master and slave operation modes.

Diagnostic Functions and Status Monitoring

Five front-panel LEDs provide clear visual feedback on communication status. A green “Power” LED confirms the presence of supply voltage. A “Run” LED indicates normal module operation and scanning. A red “Error” LED signals communication faults or configuration errors. Individual LEDs show data activity on each RS-485 port. These indicators enable operators to verify network health without diagnostic tools.

Energy Consumption and Environmental Tolerance

The module draws 60 mA at 5 V DC from the backplane power supply. Power dissipation remains below 1.8 W under normal operating conditions. The unit operates reliably between 0 °C and 55 °C ambient temperature. Humidity tolerance spans 10% to 90% without condensation issues. The module carries an IP20 rating for protection against solid objects. This robust design suits automotive assembly, packaging lines, and material handling systems.
