Serial communication

The embedded Modbus EIA-485 fieldbus brings connectivity

to major automation systems. A single twisted pair cable

avoids large amounts of conventional cabling, thereby reducing

costs and increasing system reliability.

Modbus TCP to Modbus RTU gateway

Additionally SREA-01 Ethernet adapter offers Modbus TCP

to Modbus RTU gateway functionality which enables Modbus

TCP connectivity to ACS310. Please refer to SREA-01 user’s

guide for more detailed information.

Extension module

MREL-01

ACS310 has one relay output as standard. The optional

MREL-01 module offers three additional relay outputs. The

outputs can be configured for different functions by setting

selected parameters.

SREA-01 Ethernet adapter

SREA-01 Ethernet adapter with remote monitoring access

can send process data, data logs and event messages

independently, without a PLC or a dedicated on-site

computer. It has an internal web server for configuration and

drive access.

In remote locations without qualified service people on-site

it is vital to be able to monitor the drive remotely. Monitoring

and diagnostics routines can be easily implemented with

ABB’s remote monitoring tool. The remote monitoring tool

enables the connection of multiple drives to Ethernet,

to collect operational data from the process and send the

collected data to a central location for process monitoring

and further analysis.
