IMcMem()
IMcMem() sets the sizes of X, Y, M and D memory used by MC Protocol.
void IMcMem(uint16_t x_size, uint16_t y_size, uint16_t m_size, uint16_t d_size)
Commands
| Command | Arguments | Return Value | Operation |
|---|---|---|---|
IMcMem(x_size, y_size, m_size, d_size) | uint16_t x_size — Number of X input bitsuint16_t y_size — Number of Y output bitsuint16_t m_size — Number of M internal bitsuint16_t d_size — Number of D words | void | Sets the sizes of X, Y, M and D memory used by MC Protocol. |
Example
IMcMem(32, 32, 100, 100);
Precautions
- Keep calling
IMcProtocol()inloop(). - Do not confuse hexadecimal addressing for X/Y with decimal addressing for M/D.
- Do not use X/Y/M/D before allocating the pointers.
- If Cnet or Modbus reallocates shared
M/Dmemory at runtime, the addresses used by MC Protocol change. Complete all memory size settings insetup()and do not call them again at runtime. - Allocation functions do not return success status. For nonzero sizes, verify the corresponding global pointer is not
nullptrbefore accessing it.
