Resources in the Bus Terminal Controller

The memory resources assigned in the Bus Terminal Controller are shown in the System Manager in the Resources tab of the Bus Terminal Controller.

Mapping code

The mapping code is required for calculating the TwinCAT configuration (see Figure Memory for the code mapping). The percentages are added here. In the example from Fig. Memory for code mapping, 8% of the memory is allocated to the mapping calculation.

Data memory mapping

Data memory for mapping. The values are to be considered individually, i.e. each value can be up to 100%.

Other memory

Fig. Other Memory (1) "Used Near Heap" is required for the COM interface and SSB. % values.
Fig. Other Memory (2) "Used Huge Heap" is required for the ADS communication. % values. This value should be less than 30 %.
Fig. Other Memory (3) "Used File Area" is required for the TwinCAT configuration, the TSM file and the 16 kbyte flash access. % values.
