Getting started with LOGO! Which communication modules are available? LOGO! communication module (CM) AS interface, that is described in more detail in a separate documentation. The communication module has four virtual inputs and outputs, and acts as an interface between an AS-Interface system and a LOGO! system.
Page 12 Getting started with LOGO! The LOGO! system offers you many solutions such as for small domestic installations, simple automation tasks, and even complex engineering tasks involving its integration into a bus system (e.g. communication module AS inter- face). Note LOGO! Basic may only be equipped with expansion mod- ules of the same voltage class.

2 LOGO! installation and wiring General guidelines Please note the following guidelines for installing and wiring your LOGO! : Always ensure that the wiring of your LOGO! is compliant with current rules and standards. Also, conform with all national and regional regulations when you install and operate the devices.
Page 24 LOGO! installation and wiring Do not connect an external power supply in parallel to the output load of a DC output. This could develop a reverse current at the output if you have not installed a diode or similar barrier device. The CM EIB/KNX must have its own power supply (24 V).

LOGO! functions 4.1 Constants and connectors – Co Constants and connectors (= Co) represent inputs, outputs, flags and constant voltage levels (constants). Inputs: 1) Digital inputs Digital inputs are identified with an I. The number of the digital inputs (I1, I2, ...) corresponds to the number of the input connectors of the LOGO! Basic and of the connected digital modules, in the order of their installation.
Page 121 LOGO! functions There are also 16 blank outputs available. These are identi- fied with an x and can not be reused in a circuit program (in contrast to flags, for example). The list shows all pro- grammed blank outputs, and one blank output which is not yet configured.
Page 122 LOGO! functions Startup flag Flag M8 is set in the first cycle of the user program and can thus be used in your circuit program as startup flag. This signal is automatically reset after the circuit program has completed its first cycle. The M8 flag can be used in all further cycles for setting, deletion and evaluation procedures in the same way as other flags.

Page 311: B Determining The Cycle Time
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 read- ing out of the outputs. The cycle time is the time required to execute a circuit program once in full.
Page 312 Determining the cycle Press " On =1000 G_T=02:00s Off=0000 3. Now start the circuit program and switch LOGO! to pa- rameter assignment mode. In this mode, view the trigger parameters. On =1000 Off =0000 = total of measured pulses per timeb fa =0086 4.
