1 logo! manual a5e00119092-01 1 working with logo! what is logo! ? logo! represents the universal siemens logic module. logo! integrates controls an operating and display unit power supply interface for expansion modules an interface for program modules and a pc cable readytouse basic functions that are often required in daytoday operation, e.g. functions for on/off delays, current impulse relays and softkey time switch binary markers inputs and outputs according to the device type what can logo! do ? logo! offers solutions for domestic and installation engi- neering (e.g. for stairway lighting, external lighting, sun blinds, shutters, shop window lighting etc.), switch cabinet engineering and mechanical and apparatus engineering (e.g. for gate control systems, ventilation systems, or rain- water pumps etc.). logo! can also be implemented for special control sys- tems in conservatories or greenhouses, for control signal processing and, by connecting a communication module (e.g. asi) for distributed local controlling of machines and processes. special versions without operator and display unit are avail- able for series production applications in small machine, apparatus, switch control and installation engineering.
logo! manual a5e00119092-01 2 which new types of equipment are now available? logo! basically, there are two voltage classes: class 1 < 24 v, that is, 12 v dc, 24 v dc, 24 v ac class 2 > 24 v, that is, 115...240 v ac/dc in versions: with display : 8 inputs and 4 outputs. without display : 8 inputs and 4 outputs. each version is integrated in 4 units. it is equipped with an expansion interface and offers you 30 readytous basic and special functions for creating your program. which new expansion modules are now available? the logo! digital module is available for 12 v dc, 24 v dc and 115...240 v ac/dc, with 4 i/os. the logo! analog module is available for 12 v dc and 24 v dc, with 2 inputs. the logo! communication module, e.g. the function module asi (as interface bus system). this module is described in a separate documentation. the digital/analog modules are integrated in 2 units. each one has two expansion interfaces for connecting additional modules. which type of equipment is obsolete? all versions with 6 inputs. a long variant with 12 inputs and 8 outputs the bus version with 12 inputs and 8 outputs. the modular strikers of logo! replace this type of equip- ment. it's your choice the different basic versions and expansion modules offer structures and precise adaptation to you specific tasks. logo! provides solutions ranging from the small domestic installation through small automation tasks to extensive tasks integrating a bus system (e.g. the as interface). working with logo!
3 logo! manual a5e00119092-01 note every basic logo! unit can be expanded with expansion modules of the same voltage class. mechanical encoding (pin in the housing) prevents interconnection of devices of different voltage classes. exception : the left interface of the analog module or communication module is separated from potential. this means that these expansion modules can be con- nected to devices of a different voltage class. see also chapter 2.1 'structure of the modular logo!'. regardless of the number of modules connected to the logo!, the following i/o and memory bits are available: i1 to i24, ai1 to ai8, q1 to q16 and m1 to m8. working with logo!

93 logo! manual a5e00119092-01 4.3.1 designation of the inputs logical inputs here you find the description of the connections which can be linked to other modules or inputs of the logo! device. s (set): input s can be used to set the output to a1o. r (reset): the reset input r has priority over all other inputs; it switches the outputs to a0o. trg (trigger): this input is used to trigger the start of a function cycle. cnt (count): this input is used to capture count pulses. fre (frequency): frequency signals to be evaluated are input with this designation. dir (direction): this input, for example, determines the direction of count. en (enable): this input enables the block functions. when this input is a0o, the block ignores all other signals. inv (invert): the output signal of the block is inverted when this input is set. ral (reset all): all internal values are reset. connection x at the inputs of the special functions the inputs of the special functions are 0 when connected to the connection oxo. that is, the inputs are 'lo'. logo! functions
logo! manual a5e00119092-01 94 parameter inputs to some of the inputs you do not apply signals, but rather assign specific values to the function block. par (parameter): this input is not wired. here, you configure the block parameters. t (time): this input is not wired. here you configure the times for a block. no (cam): this input is not wired. here, you configure the time pat- terns. p (priority): this input is not wired. here, you specify priorities and determine whether or not a message must be acknowl- edged in run mode. 4.3.2 time response parameter t with some of the special functions it is possible to config- ure a time value t. when specifying the time, please note that the values to be entered depend on the set timebase: timebase _ _ : _ _ s (seconds) seconds : 1 / 100 seconds m (minutes) minutes : seconds h (hours) hours : minutes b01:t t=04.10h+ setting the time t to 250 minutes: unit in hours h: 04.00 hours 240 minutes 00.10 hours +10 minutes = 250 minutes logo! functions
95 logo! manual a5e00119092-01 note always specify a time t 0.10 s. the time t is not de- fined for t = 0.05 s and t= 0.00 s. accuracy of t all electronic components have slightly different parame- ters. this can cause deviations in the configured time t. with the logo! the maximum deviation is 0.02 %. if 0.02 % of time t is smaller than 0.1 seconds the maxi- mum deviation is 0.1 seconds. example: the maximum deviation for 1 hour (3600 seconds) is 0.02 %, that is, 0.72 seconds. the maximum deviation for 1 minute (60 seconds) is 0.1 seconds. timer switch accuracy in order to prevent inaccuracies of clock timing in the c versions as a result of this deviation, the timer switch is continuously compared with a highly accurate timebase and readjusted. this results in a maximum timing deviation of 5 s/day. 4.3.3 buffering the clock the internal clock of a logo! continuous operation even on power failure, that is, the clock is buffered. the duration of this buffering is influenced by the ambient temperature. at an ambient temperature of 25 c the buffering time is normally 80 hours. 4.3.4 retentivity for special functions there is a possibility to keep circuit states and counter values retentive. this, however, re- quires that retentivity is enabled for the respective func- tions. an exception is the principally retentive operating hours meter. see also chapter 6.1 on the description of modules. logo! functions
