Additional RS-232C ports

AC 800M   CPU module   Various CPU modules can provide different functions, processing capacity, memory and redundancy support. Each CPU module is equipped with one or more Ethernet ports to exchange data with different controllers or interact with operators, engineers, managers and higher level applications. When availability becomes the most important, these Ethernet ports can be configured as redundant. Each CPU module is also equipped with two RS-232C ports, which can exchange point-to-point data with programming/debugging tools or third-party systems and devices.       Com and I/O module   For each CPU module, multiple communication and I/O modules can be added, such as:   ·Additional RS-232C ports   ·PROFIBUS DPDP - V1 interface   ·ABB INSUM interface   ·MasterBus 300 bus interface   ·S100 interface   ·S800L and S800 modules
