Programming IDEC SmartRelay
3.2 Blocks and block numbers
Advantages of block numbers
You can connect almost any block to an input of the current block by means of its block
number. In this way, you can reuse the interim results of logical or other operations, reduce
programming effort, save memory space and clean up your circuit layout. To do so, however,
you need to know how IDEC SmartRelay has named the blocks.
Note
An organizational program chart can be a valuable aid when you create the circuit program
because you can enter in this chart all the block numbers that IDEC SmartRelay assigns.
By using the WindLGC software to program IDEC SmartRelay, you can directly create a
function chart of your circuit program. WindLGC also allows you to assign 12-character
names to up to 100 blocks, and to view these on the IDEC SmartRelay onboard display in
parameter assignment mode. See the topic "The four golden rules for operating IDEC
SmartRelay (Page 57)".
