5. CONFIGURATION
5.5.14.2.1. Digital Input Double Points
For the digital input modules it is needed two auxiliary variables’ declaration, to be mapped on the digital input module,
besides the double point that is wished to map on the server:
The double point value variable: type DBP
The simple point OFF/TRIP value variable: type BOOL
The simple point ON/CLOSE value variable: type BOOL
Figure 117: Double Point Variables Declaration Example
Done the variables declaration, it is necessary to create a link between the value variables and the digital input module
quality, through the CPU’s Internal Points tab:
Figure 118: Double Point Variables Attribution to Internal Points
The double point value variable must be mapped at the server IEC 60870-5-104 driver, and both simple variables at the
Nexto Series digital input module (in that example, a NX1001). Typically the OFF (TRIP) state is mapped to the even input
and the ON (CLOSE) state to the odd input.
