R-KEY-LT Profinet (HW rev. E0)

The R-KEY-LT Profinet network gateway features a compact, space-saving design. It provides an excellent price-performance ratio, universal use and optimised network-integration costs. R-KEY-LT transmits data bidirectionally between Profinet IO and ModBUS RTU / TCP-IP industrial networks. Equipped with 1 serial port and 1 100 BaseT Ethernet port, on the Profinet IO side the device is compatible with the most common PLCs supporting the same standard. On the ModBUS side, it operates as a Master device on the serial line, capable of controlling a subnet with 128 ModBUS RTU slave nodes. In ModBUS TCP-IP it can connect to 3 ModBUS TCP-IP servers. The device autonomously reads device registers over the serial bus or Ethernet and allows a Profinet IO controller to access them, with a maximum of 512 bytes for reading and 512 bytes for writing. Configuration and diagnostics are carried out using the Simatic TIA PORTAL environment (when integrating systems with Siemens PLCs) and/or CODESYS softPLC.
