The structure contains information about the bus condition and the condition of several slaves. The information is stored in bit-fields. In this way information about the master and the condition of the fieldbus is available. Furthermore it can be read, which slaves are configured and in use, which slaves are active and inactive and which slaves contain diagnostic information. The driver function DevGetTaskState is called internally. The result is written into a DB. To be able to use the function, the information to the function should be extracted from the Hilscher manual dpm_pie.pdf. The DB should comply with the DPM_DIAGNOSTICS structure described there.

The basic configuration features of the CIF-cards are set here.
If no PROFIBUS® is used, the configuration has to be executed with the System Configurator SyCon of the Hilscher company.
How the driver is integrated into S7-SoftPLC is part of these instructions:
Using Status and Control SFC
Querying CIF-status
To query the CIF-status the status SFC has to be called cyclically (e.g. from the OB 1). The SFC contains the following parameters:
| Name | Sort | Type | Function |
|---|---|---|---|
| HostFlags | OUT | BYTE | HostFlags |
| DevFlags | OUT | BYTE | DevFlags |
| CALL | SFC 252 | |
| OUT0 | :=MB10 | // HostFlags |
| OUT1 | :=MB11 | // DeviceFlags |
The HostFlags and DeviceFlags are described exactly in the section Control-SFC function 141 and function 142, as well as in the Hilscher document tke.pdf on page 8.
Control-SFC
The Control SFC is used to execute special functions of the CIF-card. The control block is called in the following way:
| L | #Value | |
| T | MD 20 | |
| CALL | SFC 210 | |
| IN0 | := 142 | // INPUT Function number. |
| IN1 | := 0 | // INPUT Data block number (on DB operationen, else 0). |
| IO2 | := MD 20 | // IN_OUT Parameter of function / Result. |
| OUT3 | := MW 24 | // OUTPUT Default 80xx Error codes, 0 on success. |
When succeeded, the BR bit is set as well.
Control-SFC functions overview
| Function number | Function description |
|---|---|
| 102 | Set number of digital in/outputs |
| 108 | Set number of analog in/outputs |
| 125 | Read process inputs |
| 126 | Write process outputs |
| 130 | Read global diagnostic bits |
| 131 | Read bus status |
| 132 | Read incorrect bus address |
| 133 | Read error number |
| 134 | Read status bits |
| 135 | Read diagnostic bits |
| 136 | Read dual-port memory |
| 137 | Write dual-port memory |
| 140 | Trigger watchdog |
| 141 | Read HostFlags |
| 142 | Read DevFlags |
| 150 | Call DevGetTaskState and provide result in DB |
| 151 | Call DevGetInfo and provide result in DB |
| 152 | Call DevGetTaskParameter and provide result in DB |
Function 102 Set number of digital in/outputs
With this function the number of the digital in/outputs can be set. 512 byte digital in/outputs are preset in S7-SoftPLC. With this function the number of digital in/outputs can be reduced. That causes an acceleration of S7-SoftPLC. If the function was not executed successfully, the BR is not set. The return value contains the standard 80xx error codes.
Error code:
