CPU Modules
Several CPU modules are available that vary in terms of processing power, memory size, and redundancy support. Each CPU module is equipped with built in Ethernet port(s) for communication with other controllers and for interaction with operators, engineers, managers, and higher level applications. These ports can be configured for redundancy for those cases where availability is of paramount importance. It is also equipped with two RS-232C ports that can be used for point-to-point communication with programming/debugging tools and with third-party systems and devices.
Com and I/O Modules
To each CPU module, a number of communication and I/O modules can be added,
for example:
- Additional RS-232C ports
- PROFIBUS DP, DP-V1 interface
- ABB INSUM interface
- MasterBus 300 interface
- S100 I/O interface
- S800L and S800 I/O modules
