Communication between Delta HMI and PC

Before performing any communication, it is better to understand the hardware interface of Delta Hmi TP04 series and how to set the communication settings in TPEditor software program. Please refer to the following sections for the method of communication.

An external 24V DC power is required when activating TP04 series. After the power is in connected to TP04 series, the start-up display will show up first and then the system main menu of TP04 series will appear. Choose “4.TP SETUP” > “1.Communication Protocol”.

There are three items regarding the communication settings:

• TP Settings: It is used to set the communication address of TP series.
• RS232: It is used to set the transmission speed (baud rate), data length, parity check, and stop bit of    RS-232 communication.
• RS485: It is used to set the transmission speed (baud rate), data length, parity check, and stop bit of RS-485 communication.

The above three items should be set in accordance with the settings set in Tools(T) > Communication Settings(C) to ensure the correct communication (Figure ). After selecting Tools(T) > Communication Settings(C), the Communication Setting dialog box will open (Figure ) and the users can set TP Station Address, PC COM Port and Baud Rate these options. Please ensure that the actual communication address of TP series and the settings set in TPEditor must be the same; otherwise a communication error may occur.
