1.6.1 Architecture of the PCD3.T668
The PCD3.T668 remote I/Os are exclusively for use with the PCD3.M6880
Standby Controllers. With the exception of the redundancy function, they support
the same properties/functions as the PCD3.T666 remote I/O station. The PCD.
T665 and PCD3.T666 standard remote I/Os cannot be used with Standby
Controllers.
Can be used as a simple local I/O station or an intelligent programmable
I/O station
Can be programmed with the PG5. Important or timecritical tasks can be
processed directly in the RIO
The RIO‘s user programs are managed centrally by the Smart RIO Manager
(PCD) and downloaded to the RIOs automatically
Cross-communication with other PCD systems using Ether-S-Bus (FBoxes)
Intelligent communication modules (e.g. M-Bus, DALI) are supported
Other communication protocols (e.g. Modbus) via Ethernet TCP/IP and
also by the onboard RS-485 interface
Integrated Web Server
