Integrated digital inputs / outputs, supports direct connection process. Other uses integrated technology projects include: Counting frequency pulse width modulation measurement cycles Design CPU 312C equipped with: a microprocessor; processor time per binary instruction up to 100 ns?????. ? Extended memory; speed 64 KB working memory (equivalent to about 21 K instructions) for the implementation of relevant procedures, provide adequate space for user programs; SIMATIC Micro Memory Card (up to 8 MB) as the load memory program, but also allow the project (including symbols and comments) are stored in the CPU. ? Flexible expansion capabilities for up to eight modules (1 row structure)? MPI multi-point interface built-MPI interface can simultaneously build up to six with S7-300/400 or PG, PC, OP connections. In these connections, always were PG and OP each retain a connection. By "global data communication", MPI can be used to create up to 16 CPU consists of a simple network. ? Built-in input / output; 10 digital inputs (can be used for alarm handling) and 6 digital outputs, the signal for the process to connect to CPU 312C. ? Functions password protection; user program is password protected to prevent unauthorized access. ? Block encryption; Functions (FC) and function blocks (FB) by S7-Block Privacy, encrypted and stored in the CPU in order to protect our proprietary technology. ? Diagnostics buffer; diagnostic buffer can store the last 500 errors and interrupt events, including the 100 events can be long-term storage. ? Maintenance-free data backup; If power failure occurs, the CPU can be maintained all the data is automatically written to the SIMATIC Micro Memory Card (MMC card) and will remain unchanged when the power again. The feature can be parameterized using the configuration, attributes, and the CPU in STEP 7 S7's response parameter settings: an overview; definition name, host name and location ID start; startup characteristics define and monitor the CPU cycle time / clock??? memory; specified maximum cycle time and load, set the clock memory address. ? Memory;? Settings remain district-day interrupt; setting the start date, start time and duration period of the periodic interrupt;? Cycle setting system diagnostics;? Treatment and diagnostic messages to determine the scope of the clock;? Setting the AS or ? synchronization type MPI on the degree of protection;? define access programs and data communications; keep connected source MPI multi-point interface;? define the station address digital input / output address settings, input and process interruption integrated relay function "?? Counter "set address, as well as" continuous count "," single count "" Cycle Count "" Frequency Measurement "and parameter assignment" pulse width modulation "mode display function and functional status information and fault indication;?-emitting diode display, For example, hardware, programming, timer or I / O error and operating modes, such as RUN, STOP, Startup. ? Test function; using the programmer, the user can display the signal status process execution, independent modification process variables in the user program, and the output stack memory. ? Messaging; programmer in text form by providing storage capacity information for the user, the operating mode of the CPU and main memory and load memory current usage, contents of the current cycle time and diagnostic buffer. ? Integrated communication functions PG / OP communication Global data communication S7 basic communication S7 communication (only server) integration features counter;???? 2-channel (up to 10 kHz), with independent direction comparator can be connected directly to the 24V incremental encoder. ? Two channel frequency measurement; allowing frequency measurements (up to 10 kHz), for example, the spindle speed or the throughput (the number of items within each measurement period). ? Period measurement 2 channels. Measurable count signal cycle time, counting frequency up to 1 KHz. ? Pulse width modulation; two outputs can be connected directly to the control valve, the actuator, the switching device, heating devices, such as sampling frequency of 2.5 kHz. You can set and change the duty cycle length at runtime. ? Alarm inputs (all digital inputs); alarm input can detect the sequence of events, and triggers a response in the shortest possible time.
