IDEC SmartRelay Manual
3.7 Memory space and circuit dimensions
The size of a circuit program in IDEC SmartRelay is limited
by the memory space (memory used by the blocks).
Memory areas
•
Program memory
:
IDEC SmartRelay allows only a limited number of blocks
in your circuit program.
The second limitation is based on the maximum number
of bytes a circuit program may contain. The total number
of bytes used can be determined by adding up the num-
ber of bytes used for the relevant function blocks.
•
Retentive memory (Rem)
:
In this area, IDEC SmartRelay stores process variables
which need to be retentive, e.g. the hours counter value.
Blocks with optional retentivity use this memory area only
if this function is actually enabled.
