Block representation on the IDEC SmartRelay display
The figure below shows a typical view of the IDEC
SmartRelay display. As you can see, it can show only one
block at a time. We have therefore introduced block numbers
to help you check the circuit structure.

Assigning a block number
IDEC SmartRelay assigns each new block in a circuit
program a block number.
IDEC SmartRelay uses these block numbers to indicate the
block interconnections. This means that these numbers are
mainly an aid to your orientation in the circuit program.

Scrolling the circuit program using the key
The figure above shows you three views of the IDEC
SmartRelay display, which represent the circuit program. As
you can see, IDEC SmartRelay interconnects the blocks
using their numbers.
