Commissioning the CANopen Logic bus
Preparing the restart
70 L DMS 4.2 EN 07/2011 TD17
8.9.3 Special features of the I/O-System IP20 (EPM-Txxx)
Thus the following strategies are possible for the I/O system restart:
Automatic:
You want the control to automatically initialise the I/O system after the device has
been replaced.
Operate the I/O system in CANopen mode.
Enter all required parameter values in the Control Configuration under the Service
Data Objects tab.
Go to the Parameters tab and do not
set a checkmark at "Reset Node" in order that
the control does not execute a factory adjustment.
Go to the Parameters tab and set a checkmark at Create all SDOs in order that the
control initialises all parameters.
After changing the I/O system:
Set the node address and baud rate at the coding switch for the CANopen mode and
then start the control.
Using the »Engineer« or the »Global Drive Control«:
1. You have implemented the I/O system successfully into the PLC program.
2. You have parameterised some codes of the I/O system using the »Engineer« or the
»Global Drive Control«.
3. You do not want to transmit the parameter setting to the control configuration now,
since you can assume that after a possible device replacement a project planning tool
will be available.
Operate the I/O system in CANopen mode.
Go to the Parameters tab and do not
set a checkmark at "Reset Node" in order that
the control does not execute a factory adjustment.
Keep the »Engineer« project or the »Global Drive Control« file at the machine.
After changing the I/O system:
Set the node address and baud rate at the coding switch for the CANopen mode and
transmit the archived parameter setting to the I/O system. Then start the control.
Note!
For the SDO initialisation of the I/O system, please observe that ...
a factory adjustment sets the I/O system to the system bus mode.
In connection with control technology, set CANopen.
when being in the system bus mode, the I/O system only accepts changed
CAN settings after a "reset node" has been executed.
the control does not transmit a "reset node" after the SDO initialisation,
unless you have programmed it accordingly.
