The FANUC R-30iA and R-30iB series controllers are vulnerable to integer coercion errors, which cause the device to crash. A restart is required.
When converting from one data type to another, such as long to integer, data can be omitted or translated in a way that produces unexpected values. If the resulting values are used in a sensitive context, then dangerous behaviors may occur.
