7.4 The Recorder
The SimplIQ drive recorder mechanism enables the user to record up to eight signals
simultaneously. The recorded signals can be uploaded to the host through the
communication connection, for presentation and analysis.
SimplIQ drives operating with
CAN have two communication lines: CAN and RS-232. This arrangement enables the
recorder to use one line for performance monitoring while the machine host uses the other
line to control the
SimplIQ drive in its normal context.
This section explains how to define the recorder parameters for the SimplIQ drive, how to
launch and trigger the recorder and how to fetch the recorded data. The details need not be
of interest to most
SimplIQ drive users, because the Composer application normally operates
the recorder through a user-friendly interface.
The list of recordable signals supported by the SimplIQ drive is stored internally and can be
retrieved by the host. (Refer to the LS and LP commands in the SimplIQ Command Reference
Manual.) In addition, the SimplIQ drive can record user-program variables for tracing the
progress of user programs without interrupting them.
The following commands are relevant to the recording process:
Command Description
BG, BT, IL[N] Begins motion using software or hardware command. Start of motion
may be used to trigger the recorder.
BH Uploads recorder results.
LS Loads a record from the serial flash memory, in order to retrieve the
list of recorder signals.
RC Defines which of mapped signals should be recorded.
RG Recorder gap: specifies sampling rate of the recorder.
RL Recorder length.
RP[N] Recorder parameters: defines which event will trigger the recorder,
and the trigger position. Also defines basic time quantum for recorder
(TS or four times TS) and data to be uploaded to host by next BH
command.
RR Launches recorder and reads back its status.
RV Signal mapping: maps the IDs of the recordable signals to logical IDs
that the recorder can reference.
SR Status register, which indicates the status of the recorder: idle, armed,
triggered and recording, or ready with data.
TS Sampling time, the basic resolution of recorder.
WI[21] Actual amount of recorded data.
