Natural coding
The natural coding is used to encode data without any calculation. That’s means that integer
value will be send.
Example:
if the gateway receives the value 10.xxxx, the value 0Ah will be set in the appropriate
register. The gateway receives the value –10,xxxx the value FFF6h will be coded.
In this example, the SCADA needs to know that FFF6h is value –10, and not 65525 decimal,
by checking analogue min and max value for example.
Counters are considered as TM but subject to NATURAL coding only.

Function 05: Force Single Coil
This request function 05 is used to realise a control on an address point.
When broadcast, the function forces the same coil reference in all attached slaves.
setpoints are not available in the Modbus protocol

The query message specifies the coil reference to be forced. Points addresses are between
0…65535. The requested ON / OFF state is specified by a constant in the query data field.
A value of FF00h requests the coil to be ON.
A value of 0000h requests it to be OFF.

The normal response is an echo of the query, returned after the command has been sent to
the system.
Notes:
SCADA communication needs quick replies from the gateway. The reply returned is always
sent when the control is sent to the system. That means that the SCADA needs to check for
the digital change in order to know if the command is successful or not.
If value is incorrect, or if the control is refused for any reason ( equipment absent, equipment
present and in local mode, equipment invalid, …) an exception error 7 is returned.
