1 CPU 314C-2 PN/DP Function Password protection; a password concept protects the user program from unauthorized access. Block encryption; the functions (FCs) and function blocks (FBs) can be stored in the CPU in encrypted form by means of S7-Block Privacy to protect the know-how of the application. Diagnostics buffer; the last 500 error and interrupt events are stored in a buffer for diagnostic purposes. Of these, the last 100 entries are retentive. Maintenance-free data backup; the CPU automatically saves all data (up to 64 KB) in case of a power failure so that the data are available again unchanged when the power returns. Parameterizable properties The S7 configuration as well as the properties and response of the CPUs can be parameterized using STEP 7: General: Definition of the name, plant designation and location designation. Startup; definition of the startup characteristics of the CPU and the monitoring time Synchronous cycle interrupts; setting of IO system number, process image partition number, and delay time Page 1400 Mar 2008 Siemens ITS

2 Cycle/clock memory; specification of the maximum cycle time and load. Setting of the clock memory address. Retentivity; definition of the number of retentive bit memories, counters, timers and data blocks Clock interrupts; setting the start date, start time and periodicity Watchdog interrupts; setting of periodicity System diagnostics; determining handling and scope of the diagnostic alarms Clock;setting the type of synchronization in the AS or on the MPI Protection level; specifying the access rights to program and data Communication; reservation of connection resources Web; settings for the Web server of the CPU MPI/PROFIBUS DP interface; setting the interface type. Determining node addresses. Parameterizing the operating mode and configuring the transfer areas in the case of PROFIBUS DP. Parameterizing the time synchronization PROFINET interface; setting the addresses. Parameterizing the PROFINET properties, the I-Device functionality, the type of synchronization on PROFINET, the time synchronization using NTP procedure, the media redundancy, and the KeepAlive function. Assigning parameters to Port 1 and Port 2. Digital inputs/outputs; setting of addresses, input delay and process interrupt Analog inputs/outputs; setting of addresses; Page 1401 Mar 2008 Siemens ITS

3 in the case of inputs: Setting the temperature unit, the measurement type, the measuring range, and the interference frequency; in the case of outputs: Setting the output type and output range Integrated function "counting"; setting the addresses, parameter assignment of the modes "continuous counting", "single counting", "periodic counting", "frequency measurement" and "pulse width modulation" Integrated function "positioning"; setting of addresses, parameterizing of "positioning with digital outputs" and "positioning with analog outputs" Integrated "Rules" function Display and information functions Status and error indications; LEDs indicate hardware, programming, time or I/O errors, for example, and operating statuses such as RUN, STOP and start-up. Test functions; the PG is used to indicate signal states during program execution, to modify process variables independently of the user program and to output the contents of stack memories. Information functions; you can use the PG to obtain information about the storage capacity and operating mode of the CPU as well as the current loading of the main and load memories as well as current cycle times and diagnostic buffer contents in plain text.

5 Integrated functions Counters; 4 counters (up to 60 KHz) with direction-dependent comparators, and for direct connection of 24V incremental encoders 4 channels for frequency measurement; frequency measurement (up to max. 60 khz) enables, for example, speed measurement of a shaft with speed range monitoring or throughput measuring (parts per measuring time) with range monitoring. Period measurement; the period duration of the counting signal can be measured up to a counting frequency of 1 khz Pulse width modulation; 4 outputs for direct control of valves, final controlling elements, switching devices, heating equipment, etc., switching frequency 2.5 khz. The period length can be set and the pulse-pause ratio can be changed while running. Controlled positioning; an SFB integrated into the operating system enables an axis to be positioned via 2 digital outputs or one analog output. Alarm inputs (all digital inputs); the alarm inputs enable the detection of process events as well as the rapid triggering of responses. Technical specifications Page 1404 Mar 2008 Siemens ITS
