IDEC SmartRelay Manual
*: Bytes in the Rem memory area if retentivity is enabled.
Utilization of memory areas
The system indicates that there is insufficient memory space
by not allowing you to add a further 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 further
blocks you select from a block list, the system will deny
access to this list.
If memory space is fully occupied, optimize your circuit
program or install a second IDEC SmartRelay
Calculating memory requirements
When calculating the memory requirements of a circuit, you
must always take into account all individual areas of
memory.
