This is a 16-point bi-directional Digital input module.

• Input Ports: 16
• Allowable input voltage: 18~26VDC
• Input current: about 5mA @24VDC
• Input impedance: 8.2K ohm
• Input response speed: about 350uS
• ON recognition level: > 18VDC
• OFF recognition level: < 13VDC
• Floating section: 13VDC < input < 18VDC
• Status LED OFF: < 7VDC

* Up to 8 CFDI-16Bs can be used in one system with different address settings of 0~7.

1. #include “CFMEGA.h” library registration

2. CFNET object creation: CFNET object name ⇒ CFNET cfnet;

3. Use command: Object name.digitalRead(); ⇒ cfnet.digitalRead(0);

The input status of the entire specified address module is read as a 16-bit value.

• address: module dip switch value (0~7)

The port status of one pin of the specified address module is read as a 1-bit value. (1 bit read)

• address: module dip switch value (0~7)
• pin: Port number (0 ~ 15)

#include "CFMEGA.h"
 
CFNET cfnet;
 
void setup() {
 Serial.begin(9600);
}
 
void loop() {
 
 u16 blockK0 = cfnet.digitalRead(0);
 bool portIn0 = cfnet.digitalRead(0, 0);
 
 Serial.print("Block0 : "); Serial.print(blockK0, HEX);
 Serial.print(" PortIn0 : "); Serial.print(portIn0,HEX);
 Serial.print("\n"); delay(200);
}
