IEC 60870-5-101 Master Communication Module
Configuration/Error Status Flags (CfgErr)
The Configuration_Error word member of the MVI69101M_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:

Backplane Object (MVI69101M_UTIL)
The MVI69101M_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:
Name
Warmboot
ColdBoot
BPLastRead
BPLastWrite
BlockIndex
BootTimer
LoopIndex
BlockTransferSize
The other members of the object are be utilized in the ladder logic to assist in the
data transfer operation.
