Configuring identical slaves. The export of slave registers to a CSV file now includes the controlling statement and radix for each register. This enables identical slaves to be duplicated by importing the registers from the CSV file.

Configuring registers whose values should change in a similar way. The ModSlaveSim language now includes the symbol $$ to refer to 'this register' (i.e. the register associated with the statement). This symbol can be used instead of naming the register, for example, in the statement for register 42, $$ can be used instead of $42. So when a block of similar registers have values that need to change in the same way, using a self-reference, the statement for each need only be entered once. In the following example, statement 1 can be entered once for a block, but in statement 2 the register address would have to be modified for each register.

    statement 1: if $$ >= 2000 then 0 else $$ + 1.5
    statement 2: if $42 >= 2000 then 0 else $42 + 1.5

Addition of true Discrete Inputs and Coils. Register types now include 1-bit Discrete Inputs and Coils. This faciliates address-mapping where devices use true 1-bit registers, instead of Holding or Input registers, to store 1-bit values. It also eases programming of Discrete Inputs and Coils since the registers can be accessed directly without the need for bit-manipulation.

Addition of Unsigned 16-bit and Unsigned 32-bit Integers . Register types now include Uint16 and Uint32, which can be viewed in any radix. The signed types (int16, int32) are restricted to decimal radix. Note that when reading in legacy XML configuration files, registers with signed ints that have non-decimal radixes will be converted to unsigned ints.
