Programming IDEC SmartRelay

View of blocks on the IDEC SmartRelay display
The figure below shows a typical view of the IDEC SmartRe-
lay 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 a circuit program
a block number.
IDEC SmartRelay uses these block numbers to indicate the
block interconnections. Hence, these numbers primarily rep-
resent a help for your orientation in the circuit program.
