YASKAWA Machine Controller MP2000 Series

218IF-01 Ethernet Communication: Master (IP 192.168.1.2) and Slave (IP 192.168.1.3) transmit 100 word data via UDP using Extended MEMOBU protocol

MELSEC PLC connection: Read the D0000-D0063 register data of Mitsubishi PLC, store it in controller MW10000-MW10063, and automatically convert it through MELSEC protocol

Non process protocol communication: Unidirectional transmission of 254 word continuous register data, no response mechanism, suitable for custom protocol interaction

Detailed operation of each module (taking 218IF-01/02 as an example)

Module 218IF-01

Interface specifications: RS-232C (9-pin D-sub)+Ethernet (RJ-45), supporting TCP/UDP protocols

Key settings:

Ethernet parameters: IP address (default 192.168.1.1), subnet mask 255.255.255.0, port numbers 256-65535

Serial port parameters: data bits 7/8, parity bits (odd/even/none), stop bits 1/2, baud rate 9600/19200bps

Communication example: Ethernet connection between modules, Master reads Slave's MW00000-MW00063 data through MSG-SND and stores it locally in MW01000-MW01063

Module 218IF-02

Core advantages: Supports Ethernet (LP) mode, larger engineering message size, faster communication speed

Unique settings: Ethernet (LP) is selected as the logical port, 9999 is set as the engineering port, and the IP address is compatible with 218IF-01

Connection example: Ethernet connection with a personal computer, engineering debugging through MPE720 software, supporting high-speed data transmission

Maintenance and troubleshooting

1. Key points for regular maintenance

Daily inspection: Terminal fastening, cleaning of heat sink (compressed air blowing), no damage to cables

Component replacement cycle: cooling fan 2-3 years, smoothing capacitor 5 years, motor bearing 2 years/12000 hours, fuse 10 years

Safe operation: Before maintenance, the power must be cut off and wait for the capacitor to discharge (CHARGE LED to turn off); Use insulated tools and do not touch CMOS components

2. Common troubleshooting

Common causes and solutions for fault phenomena

Communication timeout (ERROR light on) IP address conflict, port number error, transmission parameter mismatch check network configuration, unified baud rate/checksum and other parameters

Data transmission error: loose wiring, ungrounded shielding layer, electromagnetic interference: re tighten terminals, optimize wiring (away from power lines), and rectify grounding

Hardware malfunction (ERR light flashing) ROM/RAM error, module not recognized, perform self diagnostic test, replace control board, reinstall module

Ethernet connection failure, network cable damage, switch failure, IP configuration error. Replace the network cable, check the switch status, and confirm that the IP is in the same network segment

3. Fault reset method

Trigger reset input signal, press the [RESET] button on the operator, turn off the main circuit power and restart

Reset premise: eliminate the cause of the fault and turn off the external operation command (FWD/REV/ORT)
