Pin Assignment

Booting the tM-P4C4 in Init Mode

Make sure the switch is placed in the “Init” position.

Connecting to the PC and the Power Supply

The tM-Series series is equipped with an RS-485 port for connection to a 232/USB converter to PC

Installing the DCON Utility

The DCON Utility is an easy-to-use tool designed to enable the simple configuration of I/O modules that use the DCON protocol.
Step 1: Locate the DCON Utility

The DCON Utility can be obtained from the companion CD or from the ICPDAS FTP site:
CD:\Napdos\8000\NAPDOS\Driver\DCON_Utility\setup\ http://ftp.icpdas.com/pub/cd/8000cd/napdos/driver/dcon_utility/

Step 2: Follow the prompts to complete the installation

After the installation has been completed, there will be a new shortcut to the DCON Utility on the desktop.

Using the DCON Utility to Initialize the tM-Series Module

The tM-Series is an I/O module based on the DCON protocol, meaning that you can use the DCON Utility to easily initialize it.

Step 1: Run the DCON Utility

Double-click the DCON Utility shortcut on your desktop.
Step 2: Use the COM1 port to communicate with the tM-Series
Click the “COM Port” option from the menu and a dialog box will be displayed that will allow you to set the communication parameters as described in the table below.

Step 3: Search for the tM-Series module
Click the “Start Search” button from the toolbox to search for the tM-Series module.
After the tM-Series module is displayed in the list, click the “Stop Search” button.

Step 4: Connect to the tM-Series
After clicking on the name of the module in the list, a dialog box will be displayed.

Step 5: Initialize the tM-Series module
Set the “Address” field in the dialog box to 1 and then click the “Setting” button to save the settings.

Rebooting the tM-Series Module in Normal Mode

Make sure the INIT switch is placed in the “Normal” position.

Starting the Module Operation

After rebooting the tM-Series module, search for the module to make sure the settings have been changed. You can double-click on the name of the module in the list to open the configuration dialog box.

Modbus Address Mapping

Baud rate, valid range: 3 – 10 Bits 7:6
00: no parity, 1 stop bit
01: no parity, 2 stop bit
10:even parity. 1 stop bit
11:odd parity. 1 stop bit| FtNV
40488| Modbus response delay time in ms. valid range: 0 – 30| FINN
40489| Host watchdog timeout value. 0 – 255. in 0.1s| FLAN
40492| Host watchdog timeout count, write 0 to clear| RAN
10033 – 10036| Digital input value of channel 0 – 3| R
10065 – 10068| High latched values of DI| R
10073 – 10076| High latched values of DO| R
10097 – 10100| Low latched values of DI| R
10105 – 10108| Low latched values of DO| R
00001 – 00004| The digital output value of channel 0 ∼3| FLAN
00129 – 00132| Safe value of digital output channel 0 ∼ 3| RAN

258| 1: Modbus ASCII. 0: Modbus RTU| RAN
260| Modbus host watchdog mode
0: same as 1-7000
1: can use AO and DO command to clear host watchdog timeout status|
Address| Description| Attribute
---|---|---
261| 1: enable, 0: disable host watchdog| RAN
264| Write 1 to clear latched DIO| W
265| DI active state, 0: normal, 1: inverse| R/W
266| DO active state, 0: normal, 1:inverse| R/W
270| Host watchdog timeout status, write 1 to clear host watchdog timeout status| RAN
273| Reset status, 1: first read after powered on, 0: not the first read after powering on| R

Note: For tM DIO modules, Modbus registers to start at 00033 or 10033 can be used to read the digital input values. For M-7000 DIO modules, they are 00033 or 10001.
