This byte is not used in replies by 1771KC/KD or KE/KF
modules.
For the other modules, the bits of this byte are defined as
follows.
1771KA and 1771KA2 modules
1771KA2 status information is opposite of 1771KA, as
noted.

2 0 = All other PLC2 Family processors (PLC2 processor for
1771KA2)
1 = PLC2 processor (all other PLC2 processors for
1771KA2)
3 0 = Protected commands enabled (disabled for 1771KA2)
1 = Protected commands disabled (enabled for 1771KA2)
