Diagnostics
Monitoring functions include:
● Detection, localization, classification of errors, faults and alarms.
● Display and further evaluation of errors, faults and alarms.
The monitoring functions run automatically during system operation. This increases the
availability of systems because commissioning times and downtimes are reduced.
Diagnostics buffer
The diagnostics buffer is a buffered memory area in the CPU in which diagnostics events are
stored in their order of occurrence.
Firmware of the CPU
In SIMATIC, a distinction is made between the firmware of the CPU and user programs.
Firmware is software that is embedded in electronic devices, i.e. functionally connected
permanently to the hardware. It is usually saved in a flash memory, EPROM, EEPROM or
ROM and cannot be replaced by the user or can only be replaced with special tools or
functions.
User program: see glossary entry "User program"
Firmware update
You use a firmware update to update the firmware of modules. A firmware update is
performed, e.g. for functional extensions of a CPU or interface module.
Function block
A function block (FB) is a code block with static data. An FB allows you to pass parameters
in the user program. Function blocks are thus suited for programming frequently recurring
complex functions, such as closed-loop controls or operating states selection.
Global data block (DB)
Every function block, every function, and every organization block can read the data from a
global data block, or write its own data to a global data block. This data is retained in the
data block, even when the data block is exited.
I/O module
Device of the distributed I/O that is used as an interface between the controller and the
process.
