    Important Notices Thank you for your selection of the 105G module. We trust it will give you many years of valuable service. ATTENTION! Incorrect termination of supply wires may cause internal damage and will void warranty. To ensure your 105G enjoys a long life, double check ALL your connections with the user’s manual before turning the power on.

  • Page 3: Important Notice

    Designers must include this Important Notice in operating procedures and system manuals. These products should not be used in non-industrial applications, or life-support systems, without consulting ELPRO Technologies first. For 105G modules, a radio licence is not required in most countries, provided the module is installed using the aerial and equipment configuration described in the 105U Installation Guide.

    Where a 105G is being used without a host device as a repeater or data-concentrator, it can be configured as “Repeater-only”. This allows the RS232/485 port to be used for on-line diagnostics. If the unit is a 105U-G-MD1, the “Repeater-only” configuration also allows this module to connect to 105S serial I/O modules.

A Write mapping is a message sending a block of values to another 105G. A Read mapping from 105G#2 to 105G#3 could be the same as a Write mapping from 105G#3 to 105G#2 (that is, in the reverse direction) - except the Read mapping is initiated from #2 and the Write mapping is initiated from #3.

The next configuration step is to transfer the I/O in the Fieldbus Interace to the Radio Interface so that the profibus I/O is available to the radio network. The 8 x digital output to be sent to the profibus slave are transferred using a fieldbus write mapping.
  • Page 86 Chapter 3 Installation 3) Radio Configuration To complete the configuration, the I/O that has now been transferred to the radio interface must be mapped over the radio network. The analog input from the slave is mapped to an analog output at a remote 105U-1, the 8 x digital output at the profibus slave will be activated in this example via appropriate mapping from 8 x digital input at a remote 105U-4 (see below).
