Configuration Errors

Improper use of the configuration protocols can cause the 750-644 I/O module to
behave unexpectedly.
There is a known configuration error when LED lights up or flashes yellow. In
this case, normal operations can be restored using the following sequence of steps:
1. Set the values of bytes 0, 1, 2 and 3 of the output process image to 0x00,
0x00, 0x00, 0x00.
2. Wait approx. 1 second.
3. Set the values of bytes 0, 1, 2 and 3 of the output process image to 0x20,
0x00, 0x15, 0x80.
4. Wait approx. 6 seconds.
Other configuration errors can be express in different ways. Normal operations
can usually be restored using the following sequence of steps:
1. Reset the system parameters back to factory settings by setting the value of
parameter 255 to 0x02 (see section "Process Image" > ... > "Parameter
Channel").
2. Reboot the fieldbus node, e.g. by briefly interrupting the power supply.
3. Reset all other parameters to factory settings by executing the Mailbox
command "SetFactorySettings, 0x57".
