The modules can be remotely controlled through a 10/100M Ethernet network by using Modbus TCP/UDP protocol. Modbus has become a standard communications protocol in industry, and is now the most commonly available means of connecting industrial electronic devices. This makes the t(P)ET-P2R2/tET-P2R2 perfect for integration into the HMI, SCADA, PLC and other software systems.
The tET-P2R2 and tPET-P2R2 contain 2 channels of photo-isolated digital inputs and 2 channels of form-A power relay outputs. The module can be used to create a DI to DO pair-connection through the Ethernet. Once the configuration is completed, t(P)ET-P2R2/tET-P2R2 module polls the status of the local DI channels and then writes to a remote DO device continuously in the background using the Modbus/TCP protocol.
The t(P)ET-P2R2/tET-P2R2 features a powerful 32-bit MCU to enable efficient handling of network traffic. It also has a built-in web server that provides an intuitive web management interface to allow users to modify the settings of the module including DHCP/Static IP, gateway/mask.
The t(P)ET-P2R2/tET-P2R2 is designed for ultra-low power consumption offering true IEEE 802.3af-compliant Power over Ethernet (PoE) using a standard category 5 Ethernet. The modules can also accept power input from a terminal block if no PoE is present.
The built-in dual watchdog timer (CPU watchdog and host watchdog) ensures continuous operation of the modules, even in harsh environments. The CPU watchdog automatically resets the CPU if the built-in firmware is operating abnormally, while the host watchdogs digital output is set with a predefined safe-value when there is no communication between the module and the host (PC or PLC) for a period of time (watchdog timeout).
