The ADDI-DATA-driver allows to access Digital I/O and Analog I/O cards from the PLC-program of S7-SoftPLC. With the ADDI-PACK software the physical IO-cards are mapped into a single virtual card. It can be accessed over functions (FC-blocks), which need to be called from the PLC-program. A cyclic data exchange over the process image does not make sense, due to the ADDI-DATA functions infrastructure.
Requirements
- The interface card has to be installed on the computer.
- The adequate drivers of ADDI-DATA have to be installed.
- The software ADDIPACK has to be installed and correctly licenced.
- The interface card has to be configured in the ADDI-PACK.
(if there are any problems, please contact the ADDI-DATA documentation and/or the ADDI-DATA support.)
- The "ADDI-DATA PC-Card" driver has to be selected in S7-SoftPLC.
Accessing the I/O card
The FC-blocks, installed by the driver in S7-SoftPLC, represent functions of the ADDIDATA.DLL provided by ADDI-DATA. These functions are transparently mapped as FC-blocks into the PLC-program. For detailed information please read the adequate documentation of ADDI-DATA. The parameter "dw_DriverHandle" described in the ADDI-DATA documentation is not required, because the S7-SoftPLC driver takes care of opening and closing the ADDI-DATA driver as well as passing the "dw_DriverHandle" to the ADDI-DATA functions.
Read8DigitalInputs:
Corresponds to the function "b_ADDIDATA_Read8DigitalInputs (DWORD dw_DriverHandle, BYTE b_Port, PBYTE pb_PortValue)".
Request:
| CALL | FC 100 | |
| INO | := B#16#0 | //b_Port |
| RET_VAL | := MW 0 | //RET_VAL error code |
| OUT1 | := MB 2 | //pb_PortValue |
The parameter IN0 corresponds to the ADDI-DATA parameter b_Port. The parameter OUT1 corresponds to the ADDI-DATA parameter pb_PortValue. The driver itself takes care of the dw_DriverHandle. The result of the function is returned in RET_VAL. This scheme applies to every driver function.
Read16DigitalInputs:
Corresponds to the function "b_ADDIDATA_Read16DigitalInputs(DWORD dw_DriverHandle, BYTE b_Port, PWORD pw_PortValue)".
Request:
| CALL | FC 101 | |
| INO | := B#16#0 | //b_Port |
| RET_VAL | := MW 0 | //RET_VAL error code |
| OUT1 | := MB 2 | //pw_PortValue |
Read32DigitalInputs:
Corresponds to the function "b_ADDIDATA_Read32DigitalInputs(DWORD dw_DriverHandle, BYTE b_Port, PDWORD pdw_PortValue)".
Request:
| CALL | FC 102 | |
| INO | := B#16#0 | //b_Port |
| RET_VAL | := MW 0 | //RET_VAL error code |
| OUT1 | := MD 2 | //pdw_PortValue |
Set8DigitalOutputs:
Corresponds to the function "b_ADDIDATA_Set8DigitalOutputsOn(DWORD dw_DriverHandle, BYTE b_Port, BYTE b_PortValue)".
Request:
| CALL | FC 103 | |
| INO | := B#16#0 | //b_Port |
| IN1 | := B#16#0 | //b_PortValue |
| RET_VAL | := MW 0 | //RET_VAL error code |
Set16DigitalOutputs:
Corresponds to the function "b_ADDIDATA_Set16DigitalOutputsOn(DWORD dw_DriverHandle, BYTE b_Port, WORD w_PortValue)".
Request:
| CALL | FC 104 | |
| INO | := B#16#0 | //b_Port |
| IN1 | := B#16#0 | //w_PortValue |
| RET_VAL | := MW 0 | //RET_VAL error code |
Set32DigitalOutputs:
Corresponds to the function "b_ADDIDATA_Set32DigitalOutputsOn(DWORD dw_DriverHandle, BYTE b_Port, DWORD dw_PortValue)".
Request:
| CALL | FC 105 | |
| INO | := B#16#0 | //b_Port |
| IN1 | := DW#16#0 | //dw_PortValue |
| RET_VAL | := MW 0 | //RET_VAL error code |
InitAnalogInput:
Corresponds to the function "b_ADDIDATA_InitAnalogInput(DWORD dw_DriverHandle, WORD w_Channel, pstr_InitAnalogInput ps_InitParameters, DWORD dw_StructSize)".
This function requires a data structure for the initialisation of an input (see card documentation). The structure is passed to the FC with an ANY-pointer of the type byte (ps_InitParameters). A seperate parameter for length of the structure (dw_StructSize) is not neccessary, it is taken from the ANY-pointer.
Request:
| CALL | FC 106 | |
| INO | := W#16#0 | //w_Channel |
| IN1 | := P#M 8.0 BYTE 10 | //ANY-pointer to structure |
| RET_VAL | := MW 0 | //RET_VAL error code |
ReleaseAnalogInput:
Corresponds to the function "b_ADDIDATA_ReleaseAnalogInput(DWORD dw_DriverHandle, WORD w_Channel)".
Request:
| CALL | FC 107 | |
| INO | := W#16#0 | //w_Channel |
| RET_VAL | := MW 0 | //RET_VAL error code |
InitAnalogOutput:
Corresponds to the function "b_ADDIDATA_Init1AnalogOutput(DWORD dw_DriverHandle, WORD w_Channel, BYTE b_VoltageMode, BYTE b_Polarity)".
Request:
| CALL | FC 108 | |
| INO | := W#16#0 | //w_Channel |
| IN1 | := B#16#0 | //b_VoltageMode |
| IN2 | := B#16#0 | //b_Polarity |
| RET_VAL | := MW 0 | //RET_VAL error code |
ReadAnalogInput:
Corresponds to the function "b_ADDIDATA_Read1AnalogInput(DWORD dw_DriverHandle, WORD w_Channel, DWORD dw_ConvertingTime, BYTE b_ConvertingTimeUnit, BYTE b_InterruptFlag, PDWORD pdw_ChannelValue)".
The function requires a pointer to the return value (see card documentation). The structure is passed to the FC with an ANY-Pointer of the type dword (pdw_ChannelValue). Please note, that the ANY-Pointer always has to have the length of DWORD 3 (12 byte).
The parameter b.InterruptFlag is not used, because it runs in polling-mode only.
Request:
| CALL | FC 109 | |
| INO | := W#16#0 | //w_Channel |
| IN1 | := DW#16#0 | //dw_ConvertingTime |
| IN2 | := B#16#0 | //b_ConvertingTimeUnit |
| IN3 | := P#M4.0 DWORD 3 | //ANY-Pointer to result |
| RET_VAL | := MW 0 | //RET_VAL error code |
WriteAnalogOutput:
Corresponds to the function "b_ADDIDATA_Write1AnalogOutput(DWORD dw_DriverHandle, WORD w_Channel, dw_ValueToWrite)".
Request:
| CALL | FC 110 | |
| INO | := W#16#0 | //w_Channel |
| IN1 | := DW#16#0 | //dw_ValueToWrite |
| RET_VAL | := MW 0 | //RET_VAL error code |
Return values:
On success RET_VAL = 0 is returned.
If an error has occurred, the error code from ADDIDATA.DLL is passed through, if possible.
If it should not be possible, the following error codes are returned:
| Error code | Reason |
|---|---|
| 0x807F | DriverHandle not available |
| 0x8042 | Error reading input |
| 0x8043 | Error writing output |
| 0x8003 | Wrong ANY-Pointer type |
| 0x8023 | ANY-Pointer does not point to a valid area or does not have the correct length |
PLC switches to STOP:
If S7-SoftPLC is switched to STOP by the driver, an error code is inserted into the diagnostic buffer, which can be read out with the programming unit (S7 für Windows®, STEP®7).
| Error code | Reason |
|---|---|
| 0xA140 | An error has occured at "i_ADDIDATA_OpenWin32Driver”. The error number of ADDIDATA.DLL is following in the next diagnostic buffer entry. |
