Combining input buffer with inputs

3.2.2.1
If the signal of a digital input (e.g. IN2D) or a signal source (e.g. 162 - Error Signal) is to be
applied to the input of an instruction, an input buffer must be set up on this digital input or
signal source. As a result, the digital input or signal source is available for the inputs of the
instructions.
1st example: Combination of an instruction input with a digital input: The signal at digital
input I4ND is to be applied to input 3 of an instruction.
Input signal settings (Boolean)
− PLC signal: e.g. 2003 - Input buffer 3
− Global source: 74-IN4D
3.2.2.2
Combination of a signal source with the input of an instruction
The signal of an analog input (e. g. MFI1A) or and analog signal source (e. g. "10 - Stator fre-
quency") is to be applied to the input of an instruction:
• In dialog window "Input settings (analog)" select a PLC signal 2301...2334.
Select a global source.
•
As a result, the analog input or signal source is available for the inputs of the instructions.
PLC signal
2301 ... 2304 - Frequency 1 ... 4
2311 ... 2314 - Current 1 ... 4
2321 ... 2324 - Percent 1 ... 4
2331 ... 2334 - Voltage 1 ... 4
2351 ... 2354 - General source 1 ... 4
Example: Combination of an instruction input with a signal source: The stator frequency is to
be applied to the input of an instruction:
In dialog window "Input settings (analog)" select a PLC signal 2301-Frequency 1...2304-
•
Frequency 4.
• Select global source "10 Stator frequency".
Combination of a fixed value with the input of an instruction
A fixed analog value (e.g. fixed frequency value) is to be applied to the input of an instruction:
In dialog window "Input settings (analog)" select a PLC signal 2601...2654.
•
Enter a value.
•
Signal source
2601 ... 2604 - Fixed freq. 1 ... 4
2611 ... 2614 - Fixed current 1 ... 4
2621 ... 2624 - Fixed perc. 1 ... 4
2631 ... 2634 - Fixed eff. volt. 1 ... 4
2641 ... 2644 - Fixed peak. volt. 1 ... 4
