Z-D-IN
5
1.
Introduction
The Z-D-IN module acquires 5 single-ended digital signals, then converts them to a digital format (IN 1-5
state).
The supported communication protocol is Modbus RTU.
The following counters are available:
4 counters at 16 bit
1 counter at 16/32 bit (configurable).
1.1.
Features
•
Acquisition of digital signals from sensor: Reed, NPN, PNP, Proximity, contact, etc...
•
Counters are saved to a non volatile memory (NVM)
•
Input signals can be filtered
•
Pulse counters for digital signals, with max frequency equal to: 100 Hz for 16bit-registers (the signal
is acquired from IN1-4); 10kHz for 32bit-register IN5
•
Node address and baud-rate configurable from Dip-Switches
•
RS485 serial communication with MODBUS-RTU protocol.
