For Quantum Safety 140CPU67160S PLC the %SW60.8 control is unavailable, hence it is not possible to have modbus port switching functionality .
Basically the system word %SW 60 is used for hot standby control functions and the bit 8 of the word %SW60 is used to control the behavior of
Modbus port in normal 67160 Quantum PLCs.
If %SW60.8 =0 address switches on Modbus port 1 during a primary swap. If %SW60.8=1 no address switches on Modbus port 1 during a primary swap.
