Modbus TCP to serial RTU/ASCII gateway
Aaxeon Technologies Inc. STM-501C Modbus TCP to Serial RTU/ASCII Gateway allows legacy Modbus RTU/ASCII devices to operate on a Modbus TCP network. It allows either Modbus serial master or slave to communicate with Modbus TCP’s slave or master.
Modbus TCP masters to Modbus RTU/ASCII slaves: The STM-501C allows multiple Modbus TCP masters to communicate with a Modbus serial network. Since Modbus serial network can only handle one query at one time, queries from different masters are pipelined and processed one by one.
Modbus RTU/ASCII master to Modbus TCP slaves: When STM-501C functions as Modbus RTU/ASCII master to MODBUS TCP slave gateway, STM-501C can connect up to 8 Modbus TCP slave. User can specify a UID range for each Modbus TCP slave.
|• DIN-Rail or panel mount;
• Supports 10/100 Mbps Ethernet;
• Supports RS-232, RS-422, and RS-485 serial interface;
• Supports LAN and WAN communications;
• Management access password protected;
• Supports up to 8 Modbus TCP master to Modbus RTU/ASCII;
• Supports inactive timeout; and
• Supports loop back mode.
The STM-501C comes with user friendly management software to configure the unit. With the software, users can also search for all serial devices within a local area network independent of its subnet. It can also find a serial device server of a specific IP address over a wide area network. Moreover, the STM-501C can also be configured by its console port, through telnet connection, or via web interface for users to configure using their web browser.
Aaxeon develops and supplies device networking and industrial communication products. Aaxeon’s main focus is to be a leading supplier of products and solutions into the rapidly growing markets of M2M (machine-to-machine) and industrial Ethernet.
