 ===== Example =====
+This example uses the MPINO-16A8R8T RS-485 port ''Serial2'', input ''D22'', and transistor output ''D39''.
 <code cpp>
+void setup() {
+  IMcMem(32, 32, 64, 64);  // Set the X·Y·M·D memory sizes used by MC Protocol.
+  IMcAdr(0, 0, 0, 0);  // Set the start addresses of X·Y·M·D memory.
+  IMcInit(Serial2, 1, 9600);  // Set the communication port, station number and baud rate.
+}
 void loop() {
-  IMcProtocol();
+  IMcProtocol();  // Check incoming requests and process MC Protocol responses.
-  X[0] = digitalRead(0);
+  if (X != nullptr) X[0] = digitalRead(22) == HIGH;
-  digitalWrite(32, Y[0]);
+  if (Y != nullptr) digitalWrite(39, Y[0] ? HIGH : LOW);

   * If Cnet or Modbus reallocates shared ''M''/''D'' memory at runtime, the addresses used by MC Protocol change. Complete all memory size settings in ''setup()'' 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 ''nullptr'' before accessing it.
