概要・特点
This product is a stand-alone remote I/O module that supports Modbus communication protocol. It supports a wide temperature range from - 25°C to 75°C, has excellent noise resistance, and is designed to withstand the environment with overvoltage and overcurrent protection circuits. It can be used for industrial applications such as plant equipment, production line monitoring, and process control. Modbus has become the de facto standard protocol for industrial communication and is now the most commonly available means of connecting industrial electronic devices. This ensures that the product provides perfect integration with HMI and other industrial control software systems.
-
Supports multiple protocols including Ethernet and Modbus TCP
- Modbus is a communication protocol widely used in the industry. It can collect and control data from upper communication devices with Modbus client function. The product supports Modbus TCP/UDP, MQTT and SNMP V2c protocols for easy integration with IT/OT systems.
-
Dual Ethernet ports (LAN bypass function / daisy-chain support)
- The LAN bypass function of the printer ensures an Ethernet communication path even when the printer is turned off, preventing loss of communication with downstream devices (daisy chain connection). This Product has a built-in two-port Ethernet switch to implement daisychain topology. The cabling is much easier and the total costs of cable and switch are significantly reduced.
-
I/O Pair Connection
- This function pairs DI (digital input) and DO (digital output) via Ethernet. Once configured, the I/O module periodically retrieves the status of the remote DI device and automatically writes to the local digital output channel using the Modbus TCP protocol.
-
Wide operating ambient temperature range: -25 to 75°C
- Designed to withstand a wide operating temperature range of -25 to 75°C (during operation). Robust design that can be used in outdoor environments with large temperature changes.
-
Built-in Dual Watchdog
- This product is equipped with two types of monitoring functions: CPU watchdog for hardware monitoring and host watchdog for communication monitoring.
• CPU watchdog: Automatically resets the CPU when a hardware or software error occurs.
• Host watchdog : If no communication is received from the host for a certain period of time, a preset safe value is output to the DO to prevent unexpected
damage to connected devices.
-
Robust ESD/EFT and surge resistance
- Passes IEC 61000-4-5 surge testing, IEC 61000-4-2 ESD testing, and IEC 61000-4-4 EFT testing. Robust design resists noise, spikes, and high-voltage electrostatic discharges.
