Yaskawa GP-PRO/PBIII Device/PLC Connection Manual chapter covering Ethernet setup between GP/GLC units and MP2300/MP920 PLCs.
This chapter of the GP-PRO/PBIII for Windows Device/PLC Connection Manual covers the Ethernet connection between Yaskawa Electric Corporation MP2300 and MP920 Series PLCs and GP/GLC units. It explains the system structure for 1:1 and n:1 connections, lists the GP/GLC units that can be used with the optional Ethernet I/F unit or a built-in Ethernet port, and describes the cables, hubs and interface units involved.
The chapter then lists the device ranges supported by the GP/GLC, gives the environment setup for both the GP unit (IP addresses, port numbers, protocol type, data code, send wait time, timeout, IP route address, subnet mask, UDP retry count) and the PLC, and ends with the PLC error codes displayed as Host Communication Error (02:**) on the GP screen.
| Supported PLC series | MP2300 Series, MP920 Series |
|---|---|
| GP Ethernet interface units | GP070-ET11, GP070-ET41, GP377-MLTE11, GP377-MLTE41, GP077-MLTE41 |
| Ethernet cable | 10BASE-T cable (IEEE802.3 compliant) |
| Communication method | TCP or UDP |
| Maximum connections per method | Up to 10 units for TCP, up to 10 units for UDP |
| Source/Destination port number range | 1024 to 65535 |
| Default 2-way driver port | 8000 (ports 8000 to 8009 used by the 2-way driver) |
| Default timeout when set to 0 | 15 seconds for TCP, 5 seconds for UDP |
| Data code setting | Binary or ASCII |
In an n:1 connection, up to 10 units can be connected for TCP communication and up to 10 units for UDP communication.
The SRC port number and the DEST port number are each set between 1024 and 65535.
The default time of 15 seconds is used for TCP communication and 5 seconds for UDP communication.
Port numbers 5001 and 5002 should not be used because they are used by the PLC's Ethernet Unit.
Settings are entered on the Parameter Setup screen of the CPMC-MPE720 Programming Software (Ver. 4.4 or later).
