7.1.18.12. Monitoring Histories of Program Execution and Changes on Control I/O
l The DP command monitors executing history of a program and history of changes on the control
Inputs and Outputs.
l The System stores the history of starts, completions and interruptions of a channel program, and
history of changes on control Input/Output in the order of occurrence. The maximum store
capacity is sixty-four histories.
l This function can be used for checking the programs of the host controller.
à Input format: DP
à When the parameter MM is set to MM1, the prompt “;” appears on the end of history
readout and the System waits for the next key entry. Pressing the SP
key reads out
history that goes one step in the past. Every one press of the R
key monitors a
current history of execution. The BS
key terminates the monitoring.
à When the parameter MM is set to MM0, the System monitors all histories together,
and then gets out the monitoring. This function is for checking histories with a personal
computer.
