151.2.2 DISPLAY-PETRA

The command with ’TRACE’ parameter is used to transfer the data that has been compiled in a trace segment of the peripheral processing system (PP) by the ’ADD’ command.
A message causes the PP to transfer the data segment with the collected TRACE data to the AMO.
The received segment is available only once. With the next interrogation job, the AMO receives a completely new segment with completely new data from the PP.
The trace data received by the PP can be output on the screen with the command "OUTPUT-PETRA" (see also the following section).

By specifying the ’DUMP’ parameter, the memory contents of a module are displayed on the console.
A message via the PP causes the modules to send their dump data to the periphery (PP) as of a specific address, and in a specific length, where the data are collected in one segment. After the last data has arrived there, they are all sent to this AMO and displayed on the terminal.
The maximum length for the data area of a DUMP job is 2048 bytes since no separate data segment is created in the periphery for a DUMP. Newer modules with an extendet DUMP-Area (e.g. STHC, SLTX) can work with DUMP jobs until 8154 Byte.
Currently, only one DUMP job at a time can be executed. Additional jobs are accepted without an error message, however, they are not executed by the periphery.

On modules with Motorolla-Processor, the address is splitted to the parameter SEG and ADR. The input for the address 86754890 for example is SEG=8675 and ADR=4890 (DISP-PETRA:DUMP,1,3,37,86,8675,4890,2048)
