478 Calc: operand out of range
Cause:
The operand of a calculation function is out of the range of valid
arguments.
The following examples apply:
• Square root of a negative number
• Logarithmic of a negative number
• Arcsine and Arccosine value must be -1, 0, 1
• Raising to a power a non integer number (fraction)
Remedy:
Use show program flow <F7> feature to locate Calc icon with error and

483 Parameter Init. Error: see Task %c diag.
There is an error in the parameter initialization or bit initialization
instruction; which is executed when exiting parameter mode. The
parameter format, parameter number, or stored value may be invalid.
A communication error message is displayed in the diagnostic message
for the task %c (where %c = task letter) in which the error occurred
(T-0-0122). Information on the actual parameter number that caused the
error is provided in extended diagnostics (C-0-0124).
Cause:
In many cases, this error is issued when a drive is not on the SERCOS
ring or the drive parameter is not found for a type of drive.
Remedy:
1. Make sure that all drives on the SERCOS ring are powered up and
enabled.
2. Check fiber optic connections.
