B.2 Procedure for data transfer
Caution
In special application cases, access with CI commands
enables parametrizing and commissioning of the SFC−DC
directly via the RS232 interface. It is, however, not suitable
for real−time capable communication e.g. for control.
Control of the SFC−DC via RS232 requires also:
an estimation of the risk by the user
ambient conditions free of interference
saving the data transmission e.g. via the control
program of the host.
·
Use preferably the control panel or the FCT for commis
sioning and parametrizing.
·
Note that control of the SFC−DC via the RS232 does not
comply with designated use.
Warning
Injury to people and damage to property.
Full access to the internal variables of the servo register
can be made via CI commands. Incorrect operation can
cause the controller to react unexpectedly and the motor
may start uncontrolled.
·
Use the CI commands only if you already have experi
ence of Service Data Objects.
·
Inform yourself about using the Objects in the CiA Draft
Standard 402 before you use the CI commands of the
Command Interpreter of the SFC−DC.
For data transfer you will require a commercially−available
terminal program.
