User Registers
User Registers (%T, %M, and %R) are used to store application-specific QX751data. This data
can be accessed via User Screens and/or by Ladder Code.
%T Register
A %T Register is a non-retentive 1-bit memory location used to store application-specific
state information.
%M Registers
A %M Register is a retentive 1-bit memory location used to store application-specific state
information.
%R Registers
A %R Register is a retentive 16-bit memory location used to store application-specific
values.
