LOGO! functions 4.3 Special Functions 4.3 Special Functions Because of their different input designation, you can see right away that there is a difference between the special functions and basic functions. Special functions (SFs) contain timer functions, retentive functions and various parameter assignment options, which allow you to adapt the circuit program to suit your own requirements.
LOGO! functions 4.3 Special Functions Connector X at SF inputs SF inputs connected to connector x are set low. That is, the inputs carry a 'lo' signal. Parameter inputs At some of the inputs you do not apply any signals. You configure the relevant block values instead. Examples: ● Par (Parameter): This input will not be connected. Here, you set the relevant block parameters (times, on/off thresholds etc.). ● No (Cam): This input will not be connected. Here, you configure the time patterns.
LOGO! functions 4.3 Special Functions Accuracy of T Because of slight tolerances in the characteristics of electronic components, the set time T can deviate. You can find a detailed description of such deviations in the "On-delay" topic (Page 160). Accuracy of the timer (weekly/yearly timer) To prevent timing inaccuracy of the real-time clock in C versions caused by this deviation, the timer value is continuously compared with a high-precision timebase and corrected.
LOGO! functions 4.3 Special Functions 4.3.4 Retentivity The switching states, counter and time values of many SFs (see the "Special functions list SF (Page 156)" topic) can be set retentive. This means that current data values are retained after a power failure, and that the block resumes operation at the break point. The timer is not reset, but resumes operation until the time-to-go has expired, for example. To enable this response, however, the relevant functions must be set retentive.
LOGO! functions 4.3 Special Functions 4.3.6 Calculating the gain and offset of analog values A sensor is connected to the analog input and converts a process variable into an electrical signal. This value of signal lies within the typical range of this sensor. LOGO! always converts the electrical signals at the analog input into digital values from 0 to 1000. A voltage of 0 to 10 V at input AI is transformed internally into a range of values from 0 to 1000.

B Determining the cycle time The program cycle is the complete execution of the circuit program, that is, primarily the reading in of the inputs, the processing of the circuit program and the subsequent reading out of the outputs. The cycle time is the time required to execute a circuit program once in full. The time required for a program cycle can be determined using a short test program.
Determining the cycle time Explanation The inverted flag block changes its output signal at each program execution. Thus, one logic level (high or low) width is exactly equivalent to the length of one cycle. Hence, a period lasts 2 cycles. The threshold trigger indicates the ratio of periods per 2 seconds, which results in the ratio of cycles per second.
