Hi, There is no need to change the type in Control Expert, you can let the WORD type. In Citect define a type with UINT and the address on the Control Expert variable type WORD and that's it.  Normally when you use a WORD format in Control Expert, it is to use Bits inside. They can be extracted in Citect with the BITAND function. If you need to read the bit 4 of a tag named MyTag (type UINT, mapped on a Control Expert variable type WORD), the function will be MyTag BITAND 0x0010. It can be used for animation, alarms or to set a DIGITAL Tag variable (Address will be MyTag BITAND 0x0010)   ... View more
