LC800 system is the second generation of Smar Logic Controllers. It includes communication port and capacity for block execution and IEC-61131-3 Ladder. In addition, the CPU800 controller has two Ethernet ports to ensure high availability of control and supervision, and also supports redundancy at all levels, providing the process with a high level of security.
Features and Limits for the CPU800 Module
Hardware
In order to preserve customers' investment, the CPU800 module accesses the same I/O cards used in the LC700 system. Through the IMB (Inter-Module Bus), present in the rack where the CPU module is mounted, up to 16 racks R-700-4A or DF93 can be interconnected, each containing up to 4 cards. In case you have a redundant controller, the DF92 rack should be used. If DF92 is used, another 16 DF93 racks can be used. Additionally, there may be a need for other power supplies depending on the number of cards.
