DCS engineer request me to address all site variable(4-20mA) connected to my slave PLC (AC 500-ABB) use his (assign address) register and each 4-20mA shall use 32bit (2 words),
The question hwo to write this register having two words?? Is below correct?
real_var_1 AT %MW40101 TO %MW40102 REAL;
or advise if there is spific format?

real_var_1 AT %MW40101 :REAL;
however the next one is not from MW40102 but from %MW40103
real_var_2 AT %MW40103:REAL;
to check this use:
VAR_INPUT
check1 AT %MW40101:WORD;
check2 AT %MW40102:WORD;
