EtherNet/IP QuickConnect™

Scope

QuickConnect is an optional functionality that may be enabled on a node-by-node basis. When enabled, QuickConnect will allow EtherNet/IP devices to quickly power up and join an EtherNet/IP network.

QuickConnect connection time is comprised of several key time durations. One factor of the QuickConnect connection time is devices power-up time. Another factor is the amount of time it takes a controller to detect the newly attached device and send a Forward Open request to start the connection process.

QuickConnect targets 500 ms as the time between initial power-up and the establisment of IO connections.

EtherNet/IP QuickConnect Target

QuickConnect measurements have been performed on the LP-AM243 launchpad and the TMDS64GPEVM evaluation module with an attached TMDS64DC01EVM high-speed extension card.

For the measurements an oscilloscope is connected to a GPIO pin on the particular board which was set to high on application start and reset to low on the first Forward Open request. The measurements were triggered by the MCU_PORz signals available on the evaluation modules. The power-up time is the time interval between the MCU_PORz signal and application start. The connection establishment is the time interval between application start and the detection of the Forward Open request.

Evaluation Module	MCU_PORz Signal	GPIO	Pin
LP-AM243	Header J6 pin 56	GPIO1_21	Header J7 pin 57
TMDS64GPEVM	Safety connector pin 24	GPIO0_41	TMDS64DC01EVM, header J8 pin 24

To enable GPIO control the example application shipped with the EtherNet/IP Adapter software is extended by two functions:

uint32_t    gpioBaseAddr;
 
void GPIO_init(void)
{
    gpioBaseAddr = (uint32_t) AddrTranslateP_getLocalAddr(CONFIG_GPIO0_BASE_ADDR);
    GPIO_setDirMode(gpioBaseAddr, CONFIG_GPIO0_PIN, CONFIG_GPIO0_DIR);
}
 
void GPIO_set(bool set)
{
    if(set)
        GPIO_pinWriteHigh(gpioBaseAddr, CONFIG_GPIO0_PIN);
    else
        GPIO_pinWriteLow(gpioBaseAddr, CONFIG_GPIO0_PIN);
}

GPIO_init and GPIO_set are called in App.c at application start and later in the Forward Open callback function.

void EI_APP_mainTask(
    void* pvTaskArg_p)
{
    uint32_t err;
 
    Board_init();
 
    Drivers_open();
    Board_driversOpen();
    GPIO_init();
    GPIO_set(true);
 
    ......

EtherNet/IP QuickConnect Controller

The QuickConnect controller device is emulated by a Python script that triggers the connection establishment upon detection of ARP announce frames.

ARP announce frame received	Request of TCP connection	Request of Register Session	Forward Open request
0.0 ms	2.494 ms	15.215 ms	26.398 ms
