HX-RIO3 Series 3.3.4. DIA (Diagnostic Status LED) Status To indicate : Device has hardware checking error. Hardware Error Flashing Red (with MOD led is red.) Device has expansion module error. Expansion Module Error Flashing Red (with IOS led is red.) Failed to initialize expansion module - Overflow Input/Output size.
An expansion module may have 3 types of data as I/O data, configuration parameter and memory register. The data exchange between network adapter and expansion modules is done via an I/O process image data by HX-RIO3 Series Internal Bus protocol. The following figure shows the data flow of process image between network adapter and expansion modules.

Plugging and Removal of the Components. As above figure to safeguard the RIO3 module from jamming, it should be fixed onto the DIN rail with locking level.
HX-RIO3 Series 5.3. G-Bus Pin Description Communication between the RIO3 series and the expansion module as well as system / field power supply of the bus modules is carried out via the internal bus. It is comprised of 6 data pin and 2 field power pins.
HX-RIO3 Series 6.PROFIBUS Electrical Interface 6.1. G-Bus System • Network Adapter Module The Network Adapter Module forms the link between the field bus and the field devices with the Expansion Modules. The connection to different field bus systems can be established by each of the corresponding Network Adapter Module, e.g.

HX-RIO3 Series 6.2.2. Terminator Resistor To minimize cable reflections and ensure a defined noise level on the data lines, the data transfer cable must be terminated at both ends with a terminating resister combination as follows.
HX-RIO3 Series 6.2.3. PROFIBUS Address Setup Each PROFIBUS Adapter could have a unique address (from 1 to 99) so that it can be addressed independently from other nodes. The address 0 is reserved to identify a broadcast exchange. No response is returned to broadcast requests sent by the master.
HX-RIO3 Series 6.2.4. Choice of PROFIBUS data transfer cable type Depending on the application, the user can choose between electrical and optical fibre data transfer cables. The following types of electrical data cables can be used: - Standard bus cable - Standard bus cable with halogen-free sheath (type FRNC) - Cable with PE Sheath for use in the food and manufacturing industries.
