RSLOGIX 5000 PLC Code Snipit

I have two DINTS lets call them Trim_Selection1 and Trim_Selection2 If a bit of Trim_Selection1 is set by the HMI all other bits must be cleared If a bit of Trim_Selection2 is set by the HMI all other bits must be cleared If a bit of Trim_Seletcion1 is set by the HMI all bits in Trim_Seletion2 are cleared If a bit of Trim_Selection2 is set by the HMI all bits in Trim_Seletion1 are cleared Simply put only one bit in either word can be set at a time
