Note
Since a UDF block is a preconfigured circuit program that you create from WindLGC for your
IDEC SmartRelay device, the memory size (program memory and REM memory) of a UDF
block depends upon the size of the function blocks contained in the UDF.
Utilization of memory areas
IDEC SmartRelay indicates that there is insufficient memory space by not allowing you to add
a block to your circuit program. IDEC SmartRelay offers you only the blocks for which it can
provide sufficient memory space. If IDEC SmartRelay memory space is insufficient to hold
any additional blocks, the system denies access to the block list.
If memory space is full, optimize your circuit program or install another IDEC SmartRelay.
