We have several methods to communicate our PC with the Delta PLC’s, and many users don’t know some of them.
On the other side, every time is more difficult to found RS232 serial ports in the computers, and the USB to RS232 converters are not as much trustable as they must, because of that I would like to list our alternatives to that problem:
Direct communication PC to PLC:
1. PC RS232 port to PLC RS232 port using the wiring DVPACAB2A30
Connecting more than one USB device simultaneously. Once you install the VCP driver, each device attached via a USB port will be assigned a different com port. In order to address a specific device, address the com port assigned to that device. Each CP210x device simultaneously connected to a PC should be programmed with a unique serial number. In this article. The WaveRT port driver combines the simplicity of the previous WaveCyclic port driver with the hardware-accelerated performance of the WavePci port driver. The WaveRT port driver eliminates the need to continually map and copy audio data by providing its main client (typically, the audio engine) with direct access to the data buffer. 3) Follow the on-screen prompts to download and install the drivers and updates. Touch Panel Drivers¶ The touch panel driver for Alpha is same as that for LattePanda V1.0. Windows 10 Drivers (V1.1) - 32Bit. Windows 10 Drivers (V1.1) - 64Bit. PLEASE NOTE: “install.bat” must be run as administrator to update the driver.
2. PC USB port to PLC RS485 port using the device IFD6500 (Delta USB-RS485 converter).
3. PC Ethernet port to PLC DVPEN01-SL module (need compatibility with high speed bus)
Communication PC to PLC trough Delta HMI (Direct Link):
The direct link capability in Delta HMI is used to communicate with the PLC and HMI with one only wire. Furthermore this capability have been improved lately and now is possible monitor both of them at the same time using only one wire. (direct Link function updated)
1. Direct Link function trough Standard USB wire (WPLSoft and ISPSoft)
2. Direct Link function trough Ethernet (WPLSoft and ISPSoft)
Exactly the same feature is available with the new DOP-B HMI’s with Ethernet embedded, really helpful for remote support.
3. Direct Link function trough USB host (WPLSoft only).
All systems are Win XP / Win 7 compatibles, so now there’s no reason to do not communicate with Delta PLC.
