FB_KL3228Config

The FB_KL3228Config function block is used to parameterize a KL3228: 8-channel input terminal for resistance sensors.

	The function block only parameterizes one terminal channel. For parameterizing all channels, the corresponding number of function blocks has to be instantiated. A mixed configuration (e.g. different sensor types) is possible.

Inputs

VAR_INPUT
    bConfigurate         : BOOL;
    bReadConfig          : BOOL;
    iSetSensorType       : INT;
    tTimeout             : TIME;
END_VAR

Name	Type	Description
bConfigurate	BOOL	A rising edge starts the configuration sequence. First, the general terminal data, i.e. "terminal name", "special version" and "firmware version", are read. Then, the specified settings are written to the corresponding registers and finally read again for verification and information. The read information is displayed at the function block outputs. During this sequence the output bBusy is TRUE, and no further command, e.g. bReadConfig, is accepted.
bReadConfig	BOOL	A rising edge starts a read sequence. The general terminal data “terminal name”, “special version” and “firmware version” are read, followed by the set configuration parameters. The read information is displayed at the function block outputs. During the read sequence the output bBusy is TRUE, and no further command, e.g. bConfigurate, is accepted.
iSetSensorType	INT	This input is used to set the sensor. The setting is based on the table below.
tTimeout	TIME	The terminal configuration or reading of the configuration must be completed within the time entered here. Otherwise an error with a corresponding error number is issued at the outputs bError and iErrorId.

iSetSensorType	Element
0	PT1000
1	NI1000
2	RSNI1000 (NI1000 according to Landis&Staefa characteristics: 1000 Ω at 0 °C and 1500 Ω at 100 °C).

Inputs/outputs

VAR_IN_OUT
    stInData  : ST_KL1501InData;
    stOutData : ST_KL1501OutData;
END_VAR

Name	Type	Description
stInData	ST_KL1501InData	Reference to the structure of the input process image.
stOutData	ST_KL1501OutData	Reference to the structure of the output process image.

Outputs

VAR_OUTPUT
    bBusy            : BOOL;
    bError           : BOOL;
    iErrorId         : UDINT;
    iState           : USINT;
    iDataIn          : INT;
    iTerminalType    : WORD;
    iSpecialType     : WORD;
    iFirmwareVersion : WORD;
    sDescription     : STRING;
    sSensorType      : STRING;
END_VAR

Name	Type	Description
bBusy	BOOL	As long as the read or configuration sequence is in progress, this output is TRUE.
bError	BOOL	This output is switched to TRUE, if an error occurred while a command (Configure or Read) is executed. The command-specific error code is contained in iErrorId.
iErrorId	UDINT	Contains the command-specific error code of the most recently executed command. It is reset to 0 by activating the function block again via the inputs bConfigurate or bReadConfig. See error codes.
iState	USINT	Corresponds to the status variable of the process data stInData.iState, see VAR_IN_OUT. During command execution (bBusy = TRUE) this output is set to 0. This output is therefore suitable for assessing the status of the terminal in normal operation. Interfering states during configuration and reading through the register communication are hidden.
iDataIn	UDINT	Corresponds to the data variable of the process data stInData.iDataIn, see VAR_IN_OUT. During command execution (bBusy = TRUE) this output retains the value it had before the command was called. This makes the output suitable for direct process data processing during normal operation of the terminal. Interfering states during configuration and reading through the register communication are hidden.
iTerminalType	WORD	Contents of register 8 (terminal name). When used with the correct terminal, the content should be 0x05DD (1501dec).
iSpecialType	WORD	Contents of register 29 (special version)
iFirmwareVersion	WORD	Contents of register 9 (firmware version)
sDescription	STRING	Terminal name, special version and firmware version as string (e.g. 'terminal KL1501-0000 / firmware 1C').
sSensorType	STRING	Set sensor type in plain text.
