 Module related Diagnostics
The Module or Identifier related diagnostics data block consist of a header byte followed by one or
more bytes containing flags, which indicate if there is diagnostics pending related to the I/O configu-
ration modules. Each flag is related to the corresponding I/O module, defined during configuration.
Non-used flags are always set to 0.
The figure below shows the header byte, and one module diagnostics byte. Depending on the num-
ber of I/O modules configured, there may be more bytes.
 Header Byte
 Module Diagnostics Byte
Bit Name Description
00 to 05 Block length These bits contain the length of the Module related diagnostics data block,
including the header byte. The Module diagnostics flags will follow this header
byte. Maximum length of the block, including the header is 63 bytes.
06 to 07 Reserved Fixed to 01.
The combination of bit 6 and 7 indicate the type of diagnostics, i.e. 01 indicates
Module related diagnostics data.
Bit Name Description
00 Module 0 Diagnostics When set, this bit indicates that there is Diagnostics information pending related
to configuration module 0, i.e. the first configuration module.
01 Module 1 Diagnostics When set, this bit indicates that there is Diagnostics information pending related
to configuration module 1.
02 Module 2 Diagnostics When set, this bit indicates that there is Diagnostics information pending related
to configuration module 2.
03 Module 3 Diagnostics When set, this bit indicates that there is Diagnostics information pending related
to configuration module 3.
04 Module 4 Diagnostics When set, this bit indicates that there is Diagnostics information pending related
to configuration module 4.
