3.3
Digital signals
The maximum number of digital signals (called
«
DIO
»
) for ENIP-2 is 32. These include DI,
DO, configurable setpoints, logical expressions, goose subscribers, diagnostics (table 3.2).
Every DIO is configured independently. For details see
«
ES Configurator manual

Digital outputs
ENIP-2 Standard and Compact provides switchgear equipment control using built-in dig-
ital outputs or using extension ENMV-1 modules, which are connected to RS-485-2 of
ENIP-2.

For built-in DO use intermediate relay if current is more than 100 mA:
−
AC: Finder 55.33.8.230.0010, Relpol (R4-2014-23-5230-WT) or similar;
−
DC: Finder 55.33.9.220.0010, Relpol (R4-2014-23-1220-WT) or similar.
Four or less ENMV modules can be connected via RS-485-2 (1 ENMV-2-4/3R-220-
А
1 plus
3 ENMV-1 or 4 ENMV-1). One ENMV-1-4/3R can control only one electrical switch.
ENIP-2 and ENMV communicate via Modbus RTU protocol.
ENIP-2 supports
Single command (<45>), Double command (<46>) over IEC 60870-5-101
or IEC 60870-5-104 and Force Single Coil (the function code 5) over Modbus.
