Before explore into the description and functions of the various subsystems, it is appropriate to introduce a general concept that applies to the entire REG System, that of the input multiplexer.
...
The REG System is totally flexible from this point of view, and allows the signal to be connected to whatever input of the boards constituting the system.
ANALOG INPUT SELECTOR
Note
The following examples and images are taken from the RegConfig software, but the same settings can also be made from the LCD display of the REG-DIN-8 board. At all points of the configuration where a temperature (and humidity) value should be (or must be) acquired, there is a drop-down menu which will be illustrated below.
...
The third field allows you to specify the various types of NTC sensor that REG System boards are capable of acquiring:PHOTO TBD
...
D = Default, indicates the reference for the board, for the REG System, default = M
M = NTC 12kOhm Beta 3977 probes (products with these characteristics are STM/STB/STE/TP-Sxx)
A = NTC 10kOhm Beta 3970 probes (products with these characteristics are STA)
S = NTC 10kOhm Beta 3435 probes (products with these characteristics are OEM)
L = is a linear reading, that is it normalizes the value read from the input from 0 to 100 (it is used in special occasions and to the manufacturer’s instruction)
R = Raw value are unprocessed value acquired in specific situations, if needed, as in the case of using the REG2VFS, it is specified in the product data sheet.
...
The first part of the field allows you to select from which board to acquire the digital input status (0 or 1). The drop-down menu lists all the boards that can potentially be present in a system:

then from the REG (REG-DIN-8) board to the expansions EXP (REG-EXP-8), IOA and IOB (REG-IOA and REG-IOB).
...
It is also possible to use the virtual digital readings acquired by the UGW via Modbus directly from the device being managed (for more information, see the REG-UGW-485 Manual).
PHOTO TBD
At the bottom of the drop-down menu, you can select 3 particular options:
...
If the REG-DIN-8 (REG), REG-EXP-8 (EXP x), REG-IOA, REG-IOB (IOA x / IOB x) or REG-UGW-485 (UGW x) boards have been selected, the channel field allows you to specify which input, among those available on the selected board type, to use for reading the status; the list that appears automatically adapts to the selected bard type, listing the available channels; for example, in the case of EXP board 8 channels appear; if an IOB type board is selected, only two channels are displayed:

As can be seen from the photos, the digital contact can be taken as either normally open (IAx) or normally closed (/IAx) to satisfy the multiple system requirements.
If VDout L or VDout H has been chosen, the channel field will be populated according to the setting that has been made except the first 13 digital outputs:

If AlarmDout has been chosen, the channel field will be populated with all the alarms available within the REG System setting:
PHOTO TBD
Obviously, they will work or not depending on the program of the specific case.
