Parameters
Parameter Declaration Data Type Memory Area Description
EN INPUT BOOL I, Q, M, D, L
n Enable
– TRUE: activates the function
– FALSE: deactivates the function
ENO OUTPUT BOOL I, Q, M, D, L
n Status
– TRUE: function executed with error
In case of an error, if one of the input values is less than or equal to zero, or if the base
has the value +1, the function sets the link result ENO to the signal state TRUE. Then the
contents of the ACCUs remain unchanged.
This function is only used to convert the FB 111 of an existing S5 program
to a function of an S7 program programmable controller.
15.4.12 FC 123 - E to Power n - E high n
The function FC 123 expects the input value in ACCU 1 as a floating point number.
1. The input value DWORD = DW#16#0000 0000 is treated the same way as the
floating point value zero (REAL = +0.0000000e+00 in accordance with DWORD =
DW#16#8000 0000).
2. The function also stores the result in ACCU 1 as a floating point number.
3. If the calculation is carried out correctly, the RLO ENO is FALSE after the function
has been called up.
Parameters
Parameter Declaration Data Type Memory Area Description
EN INPUT BOOL I, Q, M, D, L
n Enable
– TRUE: activates the function
– FALSE: deactivates the function
ENO OUTPUT BOOL I, Q, M, D, L
n Status
– TRUE: function executed with error
In the event of an error, if the input value is not within the range from
REAL = -0.8802962e+02 to REAL = +0.8802966e+02 (than the value would be outside
the number range), the function sets the RLO ENO to signal state TRUE. In this case, the
contents of ACCU 1 remain unchanged. The assignment of the auxiliary flags is not
changed.
This function is only used to convert the FB 112 of an existing S5 pro-
gram to a function of an S7 program programmable controller.
