TIM Diagnostics - Memory tab

Memory tab
The Memory tab displays current diagnostic data of the memory configuration on the TIM:
● In the Memory configuration box:
– Static flash EPROM
– Dynamic flash EPROM
– RAM
– Available RAM: Size of the free storage space available to the drivers on the TIM for
– Memory overflow: If the free RAM is no longer sufficient, a check mark appears in the
– Message memory: Size of the memory for data messages that can be stored
– Size of a memory block that is reserved for a data message.
– Number of possible message entries calculated based on the size of the message
● In the Disc configuration box:
– Storage space, used and free storage capacity of the flash or RAM disk.

TIM Diagnostics - Message buffer tab

Message buffer tab
The Message buffer tab is available only for TD7onTIM-capable TIM modules (for example
TIM 3V-IE). The tab displays the current diagnostic data on the size and utilization of the
buffer areas for messages on the selected TIM module.
With TD7onTIM-compliant TIM modules, the message buffer is divided into various buffer
areas:
● Buffer areas for data messages sorted according to destination subscribers (destination
subscriber buffers)
● Buffer areas for messages in TIM - TIM communication (TIM buffers)
● Buffer area for local communication of the CPU or an ST7cc/sc
The message buffer diagnostics function analyzes the buffer areas of the destination
subscribers in which the data frames are stored. These are of particular interest to the user.
"Total" box
The Total box provides the following information:
● Size (blocks):
Total size of the frame buffer. The value indicates the total number of message memory
blocks. This is calculated from the total size of the message memory set for the TIM and
