P1-16CDR

Discrete DC Input / Relay Output

Input Functions

This function returns the state of a single channel.

bool point = P1.readDiscrete(1,2); // Read state of slot 1 channel 2

This function returns the state of all 8 channels. It would return 0x7F if channels 1-7 are on.

uint8_t allPoints = P1.readDiscrete(1); // Read state of all channels for slot 1

Output Functions

This function writes the state of a single channel.

P1.writeDiscrete(HIGH,1,2); // Turn on slot 1 channel 2

This function writes the state of all 8 channels. It turns channels 1-7 on and turns channel 8 off.

P1.writeDiscrete(0x7F, 1); // Write state of all channels for slot 1
