Name :Cycle to the right

Symbol :ROR

Illustrate:

    The function of this type module is to move the input parameter 1 "IN" to the right cyclically to the input parameter 2 "N" bit, the result is assigned to the output parameter OUT, the BOOL type still obtains the original value after cyclically shifting any bit, when the displacement number N of BYTE type, USINT type and SINT type exceeds 8, the operation is carried out according to N%8 (remainder), when the displacement number N of UINT type, INT type and WORD type exceeds 16, the operation is carried out according to N%16 (remainder), when the UDINT type, If the shift number N of DINT type and DWORD type exceeds 32, N%32 (remainder) is calculated.

Parameter:

First input value (operand)

Second input value (number of right shifts)

Output value

Example:

LD:

ST:

Interpretation:

	IN1 and N input the corresponding type of data, and the ROR outputs the result of the cyclic rightward shift.
