S500 remote I/O with Modbus TCP

ABB provides a configurator in the Automation

Builder tool, which allows the configuration of

Modbus TCP I/O stations with the communica

tion interfaces CI521-MODTCP or CI522-MODTCP

in the same style as the AC500 configuration. For

larger applications a Bulk Data Manager tool can

be used. The configuration can be stored in the

communication interface, which allows using

the configured station with any PLC or PC that

supports Modbus TCP. This e.g. allows the use

directly on other controllers or monitoring

systems as e.g. ABB Ability™ Data Center Auto

mation or external systems.

Thanks to the Modbus feature that allows

several masters to exchange data with the same

slave, it is possible to use the I/O station as

shared devices with up to 10 PLC CPUs.
