2.1.3.2 Description
The Up counter is capable of counting binary pulses of DC 24 V at the input
CLOCK and then transmits the data to the fieldbus. The changes from 0 V to
24 V are counted.
The counter is locked with an open circuit or 0 V on input GATE. With +24 V
on input GATE, the counter is enabled.
The counter can be set or reset with the control byte.
The digital outputs DO 1 and DO 2 are activated through bits in the control
byte.
The outputs are short-circuit-protected.
The high states of the inputs GATE and CLOCK and the digital output
channels are each indicated by a green LED.
An optocoupler is used for electrical isolation between the bus and the field
side.
Any configuration of the counter modules is possible when designing the
fieldbus node. Grouping of module types is not necessary.
