StamPLC PoE

SKU:A165

Description

StamPLC PoE is an Ethernet control module designed for the StamPLC host. It supports PoE (Power over Ethernet) technology, enabling both data transmission and power supply through a single Ethernet cable. The module integrates a W5500 embedded Ethernet controller with a built-in TCP/IP protocol stack, providing 8 independent hardware sockets, a 10/100M Ethernet data link layer (MAC), and physical layer (PHY). It supports mainstream network communication methods such as UDP and TCP. The module connects to the network via an RJ45 Ethernet interface and communicates with the StamPLC host through an SPI interface. It is suitable for scenarios with high requirements for network stability and real-time performance, such as industrial automation production lines, centralized building control systems, energy and power distribution monitoring, and data center and communication equipment management in wired network access applications.

Software Notes

When using StamPLC together with the StamPLC PoE expansion module, please note the following:

1. The RST of the StamPLC LCD screen, the RST of the internal IO expander chip (PI4IOE), and the RST of the external StamPLC PoE expansion module are interconnected.
2. Some driver libraries control the RST pin when initializing the StamPLC PoE Ethernet module (W5500), causing a pin reset operation. This will also reset the already initialized screen. It is recommended to configure the RST pin as none (-1) during Ethernet driver initialization.
3. The INT pin of the internal IO expander chip (PI4IOE) is connected to the interrupt signal of the external StamPLC PoE expansion module. When the expansion module generates an interrupt signal, it may cause abnormal occupation of the interrupt bus of the IO expander chip (PI4IOE). To avoid this condition, configure the IO expander chip as follows:

Set the interrupt mask register of PI4IOE to fully disable interrupts.

#define PI4IO_REG_INT_MASK 0x11
#define PI4IO_REG_IRQ_STA  0x13
#define PI4IO_REG_CHIP_ID  0x01

static void prepare_shared_int_gpio(void)
{
#if CONFIG_ETHERNET_SPI_INT0_GPIO >= 0 && CONFIG_ETHERNET_SPI_POLLING0_MS == 0
    i2c_bus_device_handle_t pi4io = io_expander.get_device_handle();
    if (pi4io) {
        i2c_bus_write_byte(pi4io, PI4IO_REG_INT_MASK, 0xFF);
        uint8_t dummy = 0;
        i2c_bus_read_byte(pi4io, PI4IO_REG_IRQ_STA, &dummy);
        i2c_bus_read_byte(pi4io, PI4IO_REG_CHIP_ID, &dummy);
    }
    i2c_bus_handle_t bus = io_expander.get_bus_handle();
#endif
}
