Commissioning the CANopen Logic bus
Preparing the restart
 Automatic with factory adjustment:
With an automatic restart, a factory adjustment is executed.
– Enter all required parameter values in the Control Configuration under the Service
Data Objects tab.
– Set the checkmark at "Reset Node" in order that the control executes the factory
adjustment. This causes the I/O system to change to the "Lenze System Bus" mode
and remains there.
– Program a "Reset Node" in your program code. Do not use the SDO "Reset Node"
under the Service Data Objects tab. Otherwise the initialisation will be repeated
endlessly.
– 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.
8.9.4 Special features of the I/O-System 1000 (EPM-Sxxx)
There are different viable strategies for the I/O system restart:
 Automatic:
You want the control to automatically initialise the I/O system after the device has
been replaced.
– 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 and then start the control.
 Using the »Engineer«:
1. You have implemented the I/O system successfully into the PLC program.
2. You have parameterised some CANopen indexes of the I/O system using the
»Engineer«.
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.
– Save the »Engineer« project near the machine.
– After changing the I/O system:
Set the node address and baud rate at the coding switch and transmit the archived
parameter setting to the I/O system. Then start the control.
