The following variables must be linked for each temperature sensor:
- EL terminal (EL33xx):
Terminal variable | PLC variable | Comment |
---|---|---|
Value | in_PfwTempCtrlInput[...].EL_Sns_Data | Process value |
Underrange | in_PfwTempCtrlInput[...].EL_SnsUnderrun | The temperature has fallen below the lower temperature range of the sensor. |
Overrange | in_PfwTempCtrlInput[...].EL_SnsOverrun | The upper temperature range of the sensor has been exceeded. |
Error | in_PfwTempCtrlInput[...].EL_SnsError | The channel of a terminal supplies an error. |
WcState | in_PfwTempCtrlInput[...].EL_SnsWcState | If the value is 0, the terminal data is valid; if the value is 1, the data is invalid. |
AdsAddr | in_PfwTempCtrlInput[...].EL_AdsAddr | Address for communication with the terminal. |
State | in_PfwTempCtrlInput[...].EL_SnsState | General terminal status |
- KL terminal (KL33xx):
Terminal variable | PLC variable | Description |
---|---|---|
Data In | in_PfwTempCtrlInput[...].KL_SnsData | Data input |
State | in_PfwTempCtrlInput[...].KL_SnsState | Terminal state |
Data out | out_PfwTempCtrlOutput[...].KL_SnsData | Data output |
Ctrl | out_PfwTempCtrlOutput[...].KL_SnsCtrl | To register communication |
- Via aaaPfwTempMparamFromHmi[..].OutputSel_C a cooling signal is selected in the PLC, which must be linked to the System Manager by out_PfwTempCtrlOutput[...].SelOutNeg.
- Via aaaPfwTempMparamFromHmi[..].OutputSel_H a heating signal is selected in the PLC, which must be linked to the System Manager by out_PfwTempCtrlOutput[...].SelOutPos.
