PLX31-MBTCP-MBS4或DWORD將源數(shù)據(jù)值分配給目標(biāo)（適當(dāng)時擴(kuò)展符號）。INT64、UINT64或QWORD將源值直接復(fù)制到目標(biāo)，可能導(dǎo)致有符號/無符號值更改。FLOAT32或FLOAT64源值四舍五入到最接近的INT64值，并應(yīng)用上述INT64到64位INT轉(zhuǎn)換規(guī)則。如果四舍五入的源值不適合INT64，則將導(dǎo)致轉(zhuǎn)換錯誤。字符串將字符串轉(zhuǎn)換為INT64，PLX31-MBTCP-MBS4 并根據(jù)上述INT64到64位INT轉(zhuǎn)換規(guī)則進(jìn)行移動。如果字符串無法轉(zhuǎn)換為INT64（無效字符、溢出等），PLX31-MBTCP-MBS4 將導(dǎo)致轉(zhuǎn)換錯誤。

PLX31-MBTCP-MBS4 or DWORD The source data value is assigned to the destination (sign extend where appropriate). INT64, UINT64, or QWORD The source value is copied directly to the destination possibly resulting in a signed/unsigned value change. FLOAT32 or FLOAT64 The source value is rounded to the nearest INT64 value and the above INT64 to 64 bit INT conversion rule applied.PLX31-MBTCP-MBS4 If the rounded source value will not fit in an INT64 a conversion error will result. STRING The string is converted to INT64 and moved according to the above INT64 to 64 bit INT conversion rule. If the string could not be converted to INT64 (invalid chars, overflow, and so on) a conversion error will result.
The least significant source data DWORD is copied directly to the destination. FLOAT32 or FLOAT64 The source value is rounded to the nearest INT64 value and the above INT64 to 32 bit INT conversion rule applied. If the rounded source value will not fit in an INT64 a conversion error will result.PLX31-MBTCP-MBS4 STRING The string is converted to INT64 and moved according to the above INT64 to 32 bit INT conversion rule. If the string could not be converted to INT64 (invalid chars, overflow, and so on) a conversion error will result. 6.3.5 INT64, UINT64, or QWORD Source Conversion BOOL The source value of zero or one is assigned to the destination.

The least significant source data WORD is copied directly to the destination. FLOAT32 or FLOAT64 The source value is rounded to the nearest INT64 value and the above INT64 to 16 bit INT conversion rule applied. If the rounded source value will not fit in an INT64 a conversion error will result.Source Conversion STRING The string is converted to INT64 and moved according to the above INT64 to 16 bit INT conversion rule. If the string could not be converted to INT64 (invalid chars, overflow, and so on) a conversion error will result. 6.3.4 INT32, UINT32, or DWORD Source Conversion BOOL The source value of zero or one is assigned to the destination. INT8, UINT8, CHAR, BYTE, INT16, UINT16, or WORD The source data value is assigned to the destination (sign extend where appropriate). INT32, UINT32, or DWORD The source value is copied directly to the destination possibly resulting in a signed/unsigned value change. INT64, UINT64, or QWORD The most significant source data DWORD(s) are discarded (possible data loss).PLX31-MBTCP-MBS4
