Data Type Description
CfgErr Configuration Error Word for channel
CurErr Current error code for channel
LastErr Last error for channel
This information is passed to the controller from the module with each normal
read block image.
Configuration/Error Status Flags (CfgErr)
The CfgErr word member of the MVI69103M_ChannelStatus reports
configuration errors for the respective server. If the module is not functioning as
expected, inspect the value presented in this object. If a configuration error
exists, the associated bit will be set. A value of zero for the bit indicates the
configuration value is valid. This does not guarantee that the module is
configured correctly for your application. The bits used by this member are
shown in the following table.
Bit Code Description
0 0x0001 Invalid baud rate selected
1 0x0002 Invalid parity selected
2 0x0004 Received timeout set to 0
3 0x0008 Invalid Port selected for a session
4 0x0010 Invalid sector count for session
5 0x0020 Could not allocate memory for sector of a session.
6 0x0040
7 0x0080 Invalid failure delay or confirm timeout for session.
8 0x0100
9 0x0200
10 0x0400

3.1.2 Backplane Object (MVI69103M_UTIL)
The MVI69103M_UTIL object stores all the variables required for the data
transfer operation between the module and the controller. The LastRead data
member is used as the handshaking byte to indicate the arrival of new data from
the module. The structure of this object is shown in the following illustration:
Data Type Description
Warmboot Requests warmboot of the module
ColdBoot Requests coldboot of the module
BPLastRead Index of last read
BPLastWrite Index of last write
BlockIndex Computed block offset for data table
