Product Description
The Mitsubishi Electric AJ71E71 Ethernet Interface Module facilitates efficient data transfer with a 10ms response time and 32 DC input points, making it ideal for real-time control. It operates at DC 24V, consuming 5mA, and supports 10 Mbps Ethernet in half-duplex mode with baseband transmission. Cascade connections are limited to four stages, each up to 100 meters. It features eight simultaneous open connectors, a 1000-word x 8 fixed buffer, and a 3000-word x 2 random access buffer. The scan cycle includes input sampling, program execution (updating the component image register), and output refresh. User and system programs, including administration and monitoring methods, reside in system RAM. Connection is via a 15-pin male D-sub connector.
Is Your Device Showing These Signs?
The Mitsubishi AJ71E71 Ethernet module commonly experiences communication failures due to incorrect IP address configuration, subnet mask errors, or gateway settings. Firmware corruption during updates leads to operational faults, necessitating a firmware re-flash. Hardware damage to the RJ45 port or internal components causes intermittent connectivity. PLC program incompatibility or incorrect buffer memory allocation results in data transfer issues. Network conflicts with other devices sharing the same IP address range disrupt communication.
