Interfacing with the MODPORT

The MODPORT is a field I/O product created by COMFILE Technology. It is an excellent accessory for the ComfileHMI if you need to easily supplement the ComfileHMI with I/O features.

Digital I/O, Analog I/O, temperature sensing and more are all possible with the MODPORT.
The MODPORT is especially convenient because it requires no programming.
The ComfileHMI supports protocol for MODPORT.

Comfile Studio Settings

When creating a new project, select COMFILE, MODPORT as shown below.

Baud Rate is fixed at 57600,8, N, 1.
For models with RS-485 on COM3 (CHA-070WT, CHA-070WR), set the Channel to COM3.
To use MODPORT on models with only COM1, set <line> to COM1 and use a separate RS232-TO-RS485 converter.

How to connect MODPORT with ComfileHMI

Connect the MODPORT to the ComfileHMI panel PC's COM3 port.

Analog Module

Model Name	Module Type	Description	Input/Output Range	Address for HMI
MD-ADIN4	4 Channel Analog Input	13.3-bit ADC x 4	0~10V, 1~5V (4~20mA)	40101 ~ 40104

MD-DAOUT2	2 Channel Digital-to-Analog Voltage Output	16-bit DAC x 2	0~10V, 0~5V	43301 ~ 43302
MD-DAOUT2B	2 Channel Digital-to-Analog Current Output	16-bit DAC x 2	4~20mA, 0~20mA	43401 ~ 43404

How to set the address on the HMI

For bit access, select 0 as the address prefix.

For word access, select 4 as the prefix and enter the address minus 40000.

Determination of Display Value Type

For the module that reads the value, the display type must be specified. Please specify as follows.

MD-ADIN4 : 16-bit integer
MD-HADIN4 : 32-bit integer
MD-THRT4, ML-THRT1, ML-NTC2 : 16 bit temperature

Setting the Slave Address

If multiple modules of the same module are used simultaneously on one RS485 line, the IDs (slave addresses) must be set differently at this time because the addresses are duplicated.

For the MODPORT module, there is a rotary switch on the front that can be changed from 1 to 10 (0 is 10).
