Solution
- Wireless module cannot be
configured using the PSI-CONF
software
• Make sure that the wireless module is supplied with power.
• Make sure that you are using the correct cable:
– RAD-CABLE-USB (Order No. 2903447), power supply via the
USB port on the PC
– IFS-USB-DATACABLE (Order No. 2320500), external power
supply
• Install the USB driver. The driver is installed automatically during
PSI-CONF software installation (see Section 5.6, “Configuration via
PSI-CONF software”).
PWR off No power supply, mains
probably switched off.
• Switch the mains on, restore the power supply.
• Ensure the power select switch is in the correct position for the type
of power (RAD-900-DAIO6 only)
• Check the fuse (RAD-900-DAIO6)
DAT off No communication between
wireless module and I/O
extension module. Wireless
module possibly in “Serial data”
operating mode.
• Check whether the I/O extension module is properly snapped onto
the DIN rail connector and whether it is connected to the wireless
module.
• Check the operating mode of the wireless module using the
PSI-CONF software. The wireless module must either be in “I/O
data” or “PLC/Modbus RTU” mode (see Section 5.6, “Configuration
via PSI-CONF software”).
• Reset the wireless module to the default settings (I/O data mode), if
required. Disconnect the device from the supply voltage, hold down
the SET button and switch the supply voltage on again (see
“Resetting to the default settings” on page 67).
ERR on Local bus error
The input or output module is
disconnected from the DIN rail
connector and the bus.
• Check whether the I/O extension module is properly snapped onto
the DIN rail connector.
• Press the SET button on the front of the wireless module or carry out
a power up. The data of the I/O extension modules are read in again.
