ABB S500 I/O modules run with various controllers Modbus TCP
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.
