5.5.1.2 Operating mode selection
The EL1502 can be operated in four modes: The setting takes place by the
setting of single-channel operation or operation with two separate channels through the selection of the
process data objects [ } 123]
+
Counter settings (up/down counter, gated counter)
in the CoE directory [ } 115] .
The following operation modes are possible:

• UD input (terminal point 1):
sets the counting direction:
- High level: up;
- Low level: Down
• Clock input (terminal point 5):
indicates the individual pulses.
Output 1
