Chapter 6
Troubleshooting
General
Module initialized, but still unable to exchange data
• Data exchange will not take place until the module has responded to a “Set Running/Idle Mode
& Data Representation” mailbox command. (See 4-3 “Set Running/Idle Mode & Data Repre-
sentation (MB_SET_RUNNING_IDLE)”)
• Data exchange is halted when using the Configuration Interface. Disconnect the RS232 cable
when not using this interface.
I/O data seems to be on the wrong place
• The module features two modes of data representation; Byte and Nibble mode. This is config-
ured in the “Set Running/Idle Mode & Data Representation” mailbox command. (See 4-3 “Set
Running/Idle Mode & Data Representation (MB_SET_RUNNING_IDLE)”)
To read more about Byte and Nibble mode, see 2-2 “I/O Data”.
Unable to use slave address 32
• Due to the nature of the extended addressing scheme used by AS-Interface v2.1, this slave ad-
dress cannot be used.
Read the AS-Interface Specification for more information.
Configuration Interface
The Configuration Interface “freezes” when trying to connect
• Flowcontrol is not supported on this interface.
Disable flowcontrol in the terminal software.
The display is garbled up when using the Configuration Interface
• Make sure the communication settings in the terminal program conforms to the settings below:
Baudrate:
38.4kbaud
Parity:
None
Databits:
8
Stop bits:
1
Flow control: None
