1.The rack can be part of a Profibus/Profinet network. In this case the module can be configured through the Profibus/Profinet master PLC to be included in the Profibus/Profinet network.
2.If the ET200S Distributed I/O System includes an internal CPU, this can be used, in combination with the PLC, to configure the 1 SI CANopen Module for ET200S.
3.When the ET200S Distributed I/O System includes an internal CPU, it can also be used as a standalone rack. The module is configured by downloading the configuration to this CPU instead of to the PLC.
For the 1SI CANopen to feature in the hardware catalog of Step 7, a GSD file or HSP package must be installed. These files are available here for download.
Step 7 Integration
Siemens SIMATIC STEP7 tool is used to configure the ET200S Distributed I/O System rack and the 1 SI CANopen Module for ET200S for integration into the rack. The module is included in the SIMATIC STEP7 tool. The ET200S Distributed I/O System appears as a slave on the Profibus/Profinet network if it is configured from the Profibus/Profinet PLC. It can appear either as a master or as a slave on the CANopen network depending on the settings in the parameter list. Right-clicking on the 1 SI CANopen Module for ET200S in the list of modules in the rack will allow the user to define the parameters of the module.
Hot Swap Functionality
The 1SI CANopen Module supports the function "Hot Swap" and cn be removed and replaced with another module without the power being
turned off. To be able to restart the module accurately and fast, the configuration can be uploaded to the PLC when configured and downloaded to the new module once this is attached to the rack.
PLC Function Blocks Available
The upload and download of the configuration is performed by PLC function blocks, available here for download.
There is also additional PLC function blocks availble for SDO read/write and I/O fragmentation.
