1. Introduction
The M-7018 is an 8-channel Analog Input module that provides current and voltage
input, as well as thermocouple input. The M-7018 also features 4 kV ESD protection
and 3000 VDC intra-module isolation. The M-7018 is a family of network data
acquisition and control modules that support Modbus RTU. They can be remotely
controlled using a set of commands called DCON protocol. With the Modbus RTU
protocol, it can easily communicate with most popular SCADA/ HMI software and PLCs.

5. Configuration
To install the module, follow the steps below:
1. Connect the thermistor analog input.
2. Connect the module to the RS-485 network using the DATA+ and DATA- terminals. If
the host is only equipped with an RS-232 interface, then an RS-232 to RS-485
converter will be required.
3. Connect the module to the power supply using the +Vs and GND terminals. Note that
the voltage supplied should be in the range of +10 to +30V DC.

7. For M-7000 modules using the Modbus RTU protocol, configure the module using the
following functions.
Sub-function 04h of Function 46h, see user manual Section 3.3.2
Sub-function 06h of Function 46h, see user manual Section 3.3.4
Sub-function 08h of Function 46h, see user manual Section 3.3.6
For M-7000 modules using the Modbus RTU protocol, use Function 04h to read the
data from the input channels. See user manual Section 3.2 for details.
