1. Introduction
The Z-4TC module acquires up to 4 single-ended signals (voltage-type, from the: signal generator or
thermocouple) and it converts them to a digital format using the Modbus RTU Protocol.
A double serial interface (RS232 or RS485) it’s also available (Modbus RTU protocol).
1.1. Features
The information regarding technical specifications, electrical connections and functionality of the LEDs
can be found in the installation manual for each product. To consult the installation manual use the link
below:

2. MODBUS RTU PROTOCOL
The Modbus protocols supported by the Z-4TC is:
Modbus RTU Slave
for more information about this protocols please refer to Modbus specification website:
http://www.modbus.org/specs.php
2.1. MODBUS RTU DEFAULT CONFIGURATION
The RS232 port is always configured in:
Baud Rate: 2400, Data: 8Bit, Parity: None, Stop Bit 1, Modbus Station Address: 1
The RS485 port is configured from dip switch and from the Easy Setup Software.

2.2. MODBUS RTU FUNCTION CODE
The following Modbus functions are supported:
Read Holding Register (function 3)
Write Single Register (function 6)
Write Multiple registers (function 16)
2.3. MODBUS RTU Register table
An Holding Register is composed by 16 bit from 0 to 15.
The Least significant bit is represented with BIT[0], the most significant bit with BIT[15]:
A single Floating point (32 bit) register is composed by two Holding Registers.
