Regent variables can be declared in the Shared Variables lists as Control Relays (Booleans), Registers
(integers) and Floating Point Registers (reals). Variables can also be declared in the I/O connection
table as the name of I/O data points, and even implicitly as local variables inside function blocks.
Trusted variables must all be declared in the dictionary lists and used in the I/O connection table and
programs.
Regent shared variables are addressed by their position in the list, e.g. the variables here are at
Modbus address 0600 onwards. Trusted variables may be allocated individual addresses or none at
all. Regent often requires spare variables to space out the addresses; these are not needed in Trusted.
