CONNECTING TO A PLC

8.1 - Connecting to a PLC as an intelligent multiplexer

the Zen Datalogger can easily be configured as an intelligent multiplexer via the 'Retransmis-
sion' tab in Define WorkBench. To do this, select '

Multiplexer (Binary)

' as the

Retransmission

Mode

and wire the unit as shown below.

Specifications

Settling time before reading

100msec

min. Multiple readings with averaging
recommended. (Longer times may be
required for longer cable lengths and
higher resolution.)

Binary signal magnitude

5–30V DC

Cycle time

4sec min to cycle through all 16

inputs

Resolution

15 bits, 16,000 steps typical

NOTE
Multiplexer Mode uses both the Retransmission Outputs and the Digital Inputs.

Digital Inputs can no longer be configured independently via the 'Digital Inputs' tab.
