ICnetMem()

ICnetMem() sets the sizes of M, D and R memory used by the Cnet Slave.

void ICnetMem(uint16_t m_size, uint16_t d_size, uint16_t r_size = 100)

Commands

Command	Arguments	Return Value	Operation
`ICnetMem(m_size, d_size, r_size)`	`uint16_t m_size` — Number of M-area bits `uint16_t d_size` — Number of D-area words `uint16_t r_size = 100` — Number of R-area floating-point values	`void`	Sets the sizes of M, D and R memory used by the Cnet Slave.

ICnetMem(100, 100, 20);

Keep calling ICnet() in loop().
Set M/D/R sizes within the available SRAM.
When sharing memory with Modbus, check for duplicate allocation and address conventions. Both ICnetMem() and ImodbusRTUMem() reallocate shared M/D. Assign final size management to only one of them and initialize both protocols after the last reallocation.
Allocation functions do not return success status. Check whether M, D and R are nullptr before accessing them in user code.
