6 Signal List
The Signal List, an Excel file, contains all data points needed for the regulation and control task. The following
services are performed with your help:
Design guide for the switch cabinet construction
Cable list for the on-site electrician
Fault message texts for the system centre
Creation of the instances and scaling of the sensors in the CODESYS program
Interface GLT Config for visualisation in LDSWin
Commissioning log
Up to 4 controllers can be manged with one Excel file. A separate worksheet is created for each controller. The
Excel worksheets must be named DDC1...DDC4 (for the controllers 1..4 with the CAN addresses 122..125).
Using the Signal List Tool, various files are generated from the Signal List for use in the CODESYS program
(*.exp) and LDSWin (*.cfg).
No. Function Name of the source code file
1 E/A assignment
Contains all IO variables with assignment to the process image
EA_DDC_n.exp
2 Setpoints
Sets all setpoints with the "flag input words" for controllers, control
variables, ...etc. to a default value that is stored in the Signal List. These
values can be adjusted for the runtime via LDSWin.
DDC_n_Sollwerte.exp
3 Error texts
Outputs all fault messages defined in the Signal List with their priorities on
the CAN bus.
DDC_n_AlarmPrepare.exp
4 Probes and sensors
Provides the application with the instance variables of the sensors with the
respectivescaling.Thevaluesareoutputasaphysicalvalue,e.g.:24.5°C
DDC_n_Fuehler.exp
5 Visualisation Visu_DDC_n
6 GLT Config
Creates the GLT interface for the system centre for communication with
the LDSWin system. The Signal List determines which data point is
displayed in LDSWin, whether it can be changed and whether it should be
archived.
<name of the Excel file>.cfg
n stands for 1..4 for the respective controller.
The files are stored in the directory in which the Signal List is located.
