Aaxeon Technologies is proud to announce the release of our new STM-501C MODBUS TCP to Serial RTU/ASCII Gateway.  The STM-501C 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.

The STM-501C comes with user friendly management software to configure the unit.  Utilizing 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.
