8.15.1.3 Function modules
TPLE provides various function modules for processing the information.
8.15.1.3.1 AND
Description AND, logical AND link
Inputs Input 1…4 (BOOL)
Outputs Output (BOOL)
Parameter None
Function If all configured inputs are TRUE, the output is TRUE,
otherwise it is FALSE.
Initial state All inputs and outputs are FALSE.
Non-configured inputs are assumed to be TRUE.
If no input is configured, the module is not run so it re-
mains in its initial state.

8.15.1.3.2 NAND
Description NAND, logical NOT-AND link
Inputs Input 1…4 (BOOL)
Outputs Output (BOOL)
Parameter None
Function If all configured inputs are TRUE, the output is FALSE,
otherwise it is TRUE.
Initial state All inputs and outputs are FALSE.
Non-configured inputs are assumed to be TRUE so
that they have no impact on the output.
If no input is configured, the output therefore remains in
the initial state of FALSE.

8.15.1.3.3 OR
Description OR, logical OR link
Inputs Input 1…4 (BOOL)
Outputs Output (BOOL)
Parameter None
Function If one of configured inputs is TRUE, the output is
TRUE, otherwise it is FALSE.
Initial state All inputs and outputs are FALSE.
Non-configured inputs are assumed to be FALSE.
