Flip-flop block function 

The flip-flop block has two inputs:

The flip-flop block has an analog output (AA ) (16 bit) and a digital (binary) output (AB ).

Output (AB ) represents the logical inversion of output (AA ).

Coding of flip-flop block 

The flip-flop block can be configured either as a "D flip-flop" with data and clock input, or as an "RS flip-flop" with set and reset input.

When configured as a "D flip-flop", it is possible to save 16-bit signals at input 1 (E1 ) and to output them at output (AA ).

IMPORTANT Signal identification number = Signal ID.

CODING VIA DATA ENTRY TABLE

Designation in data entry table Data entry bit width Data bit evaluation Meaning
B1_G1_FF1_Typ [B1_G1_FF1_Type] 1 bit - Set value:
"RS flip-flop" → 0
"D flip-flop" → 1
B1_G1_FF1_Auswertung
[B1_G1_FF1_Evaluation]
1 bit - Set value with "RS flip-flop":
State-triggered → 0
Edge-triggered → 1
Set value with "D flip-flop":
Positive edge evaluation → 0
Negative edge evaluation → 1
B1_G1_FF1_1_Signal_ID 32 bit 1 bit: "RS flip-flop"
16 bit: "D flip-flop"
Filter + reference ID of set(S) or data (D) input signal
B1_G1_FF1_2_Signal_ID 32 bit 1 bit Filter + reference ID of reset (R) or clock (C) input signal
SIGNAL ID OF OUTPUTS (AA, AB)

Designation in signal ID list Data bit width Meaning
SPS_G1_FF1 16 bit Signal ID of output (AA )
SPS_G1_FF1_inv 1 bit Signal ID of output (AB ) (corresponds to logically inverted output (AA ))

The same applies for the other flip-flop blocks with the naming conventions:
