The 6ES5943-7UA11 is a central processing unit (CPU) designed for the Simatic S5-115U range of programmable logic controllers. The 6ES5943-7UA11 is sometimes refered to as the CPU943. The 6ES5943-7UA11 features 1 serial interface and can be replaced with the 6ES5943-7UB21 which features 2 serial interface solts.
The 6ES5943-7UA11 can be programmed in the STEP 5 programming language. For programming under GRAPH 4 the standard function block of the same name is required.
The 6ES5943-7UA11 central processing unit contains:
RAM submodules extend the internal RAM on the 6ES5943-7UA11. When the RAM submodules are removed from their receptacles in the CPU, the data is erased. Programs and data can be stored on 375 memory submodules (EPROM or EEPROM) to protect them from power failure. The memory submodule are programmed on the programming device using the receptacle provided for this purpose and are then plugged into the CPU. Direct Industrail offer a wide range of RAM submodule and can offer assitance programming these units.
The clock can be set and read. It can also be used for counting operating hours or interrupt functions
The operation system incorporates a number of functions block programmed in machine language, which can execute at extremely high speeds and do not occupy any space in the integral function blocks. These integral function blocks are called in the same way as any other blocks in the user program and can only be interrupted by process interrupts.
