Introduction

Description
Freely programmable logic modules are function blocks that process input
signals and provide binary or analog output signals according to their
internal logic components. Logic modules can contain:
• Plugs
• An internal logic component
• Sockets
• Settings, e.g. the time for a timer.
Schematic
The following schematic shows a general representation of a logic module:

Extent and application
You can use the logic modules to carry out additional functions for your
application. These can be used, for example, to implement logical
operations, time relay functions and counter functions. Depending on the
device series, the system provides several logic modules:
Truth tables 3 inputs/1 output
Truth tables 2 inputs/1 output
Truth tables 5 inputs/2 outputs
Timer
Counter
Signal conditioners
Non-volatile elements
Flashing
Flickering
Limit Monitor
Calculation modules (Calculator)*
