MLD diagnostic functions

Overview
Flow control
In addition, PLC variables of an MLD user program can be recorded
with the oscilloscope function (see "Recording PLC variables with the
oscilloscope function").
● Analog output
The drive function "analog outputs" allows analog signal values to be
used for commissioning and optimizing drives with appropriate measur‐
ing devices (e.g., oscilloscope, multimeter), as well as for visualizing the
contents of drive parameters (see Functional Description of firmware
"Analog outputs").
● Patch function
The patch function allows reading internal storage locations and PLC
variables (see functional description for the firmware titled "Patch func‐
tion").
● Error memory
In the drive, all occurred errors, together with the corresponding count of
the operating hours counter, are collected in an error memory on the
control section (see Functional Description of firmware "Error memory
(power section and control section)").
In conjunction with Rexroth IndraMotion MLD, there are other PLC-specific
diagnostic functions available (for detailed descriptions of the functions, see
the appropriate section in "PLC program development with Rexroth
IndraLogic 1.0"):
● Flow control
When "flow control" has been activated, parts of the program executed
during the last control cycle are highlighted.
● Sampling trace
Sampling trace allows exactly tracing the time flow of PLC variables.
● Watch and recipe manager
The watch/recipe manager allows loading and storing variables in sum‐
marized form.
● Visualization
PLC variables can be graphically represented or changed via the
IndraLogic user interface.
● Monitoring functions
Both the runtime and the available resources are monitored in Rexroth
IndraMotion MLD.
● Simulation
The PLC logic, for example, can be tested by means of the simulation.
● Debugging/troubleshooting
gle step, writing, forcing)
When "flow control" has been activated, parts of the program executed during
the last control cycle are highlighted.
