Does all State Ram get transferred each scan using a ProWORX32 Quantum Hot Standby system?

This is dependent upon the setting chosen in Configuration Extensions. Under Quantum Hot Standby and the General tab there are four choices. Below you will find a description of each choice.

Default (12K): All 0xxxx and 1xxxx registers (up to 8192 each) are transferred.
If 10000 or fewer 3xxxx and 4xxxx (combined) registers are configured, then all are transferred.
If more than 10000 3xxxx and 4xxxx (combined) registers are configured, then (up to) 1000 3xxxx registers and all 4xxxx (up to a combined total of 10000) are transferred.

Routine Only: All addresses defined in the routine transfer table are transferred every scan. There must be a minimum of 16 4xxxx registers to support the non-transfer area. The Routine Transfer Table is a range of discretes and registers that must be configured as a multiple of 16.

Routine and Extra: All addresses defined in the Routine Transfer Table and in the extra tables are transferred. The range of each extra table must be a multiple of 16. The extra tables can be transferred over multiple scans.

All State RAM: All RAM configured in the controller is transferred every scan.
