<strong>M238</strong> System Functions Example 2 This example shows the use of an intermediate variable for Mode input parameter. VAR MyLocalIOStatus : LOCAL_IO_GEN_STATUS; MyMode : LOCAL_IO_GET_STATUS; END_VAR MyMode := LOCAL_IO_GET_GEN_STATUS; MyLocalIOStatus := GetLocalIOStatus(MyMode); 34 EIO0000000364 04/2012
GetPlcFault: Returns Detected Errors on the Controller I/O <strong>M238</strong> System Functions Function Description This function returns a generic diagnostic of the Controller I/O in a bit field (FFFF hex means no error detected): NOTE: The similar information is also available through the System Variable (bit0 and bit1) PLC_R.i_lwSystemFault_1 (see page 16). Graphical Representation IL and ST Representation To see the general representation in IL or ST language, refer to the chapter Function and Function Block Representation (see page 71). I/O Variable Description The following table describes the output variable: Output Type Comment GetPlcFault WORD Diagnostic of controller’s I/O in a bit field (FFFF hex means no error detected). The following table details the bits contained in the output bit field: Bit Meaning 0 FALSE = detected error on the I/O expansion bus. Use the GetRightBusStatus (see page 36) function to get detailed diagnostic information. 1 FALSE = detected error on the embedded I/O. Use the GetLocalIOStatus (see page 33) function to get detailed diagnostic information. 2..15 reserved, always 1 EIO0000000364 04/2012 35
