SANYO DENKI Releases LAN Interface Card with Modbus
Contributes to stable production facility operation

August 20, 2019

SANYO DENKI CO., LTD. has added the industry standard Modbus(1) communications protocol to its LAN Interface Card, an optional product for uninterruptible power supplies (UPS).
The seamless connection between production facilities and UPSs contributes to the stable operation of production facilities.

1. Contributes to the Stable Operation of Production Facilities (Modbus Slave Function)

UPS status can be monitored from Modbus masters such as PLCs and monitoring control systems.
This card provides centralized control of the entire system’s power status, contributing to the stable operation of production facilities.

2. Monitoring by UPS (Modbus Master Function: Industry’s First(2))

The UPS acts as a Modbus master and can monitor the state of Modbus slaves, such as sensors, measuring instruments, and I/O modules. A notification email can be sent to an administrator when abnormalities occur.

3. Easy Connection to Production Facilities

Supporting the industrial standard Modbus RTU(3) protocol and the Modbus TCP(4) internet communications protocol, it can easily connect with customers' Modbus devices.

4. Ideal for Connecting to ICT Devices

Because it is compatible with our existing LAN Interface Cards, it can also be connected to ICT devices. In addition, it has a function to shut down virtual platforms and virtual operating systems such as HCI.(5)

(1) Modbus: A communications protocol which is commonly used for exchanging data between industrial devices.

(2) Based on our own market research as of August 20, 2019.

(3) Modbus RTU: A widespread variant of Modbus. Data communication is mainly carried out through RS-485.

(4) Modbus TCP: A Modbus variant used for communications over TCP/IP networks.

(5) HCI (Hyper-Converged Infrastructure): A virtual platform that combines functions such as servers and storage.
