HMS's 1 SI CANopen module for the SIMATIC ET200S I/O system has
integration of the CAN 2.0A protocol. In addition to the standard CANopen
protocol, the HMS 1 SI CANopen
module can also be used for transmission/ reception of any CAN 2.0A frame
regardless of the overlaying
CAN application protocol. Typical applications include all kinds of machines
and automation systems where CAN or CANopen enabled devices are used in
combination with Siemens PLCs.
The HMS 1 SI CANopen module fits mechanically into the standard ET200S
system rack and can be used in combination with all other modules of the ET200S
family. The module can be engineered with STEP7, allowing easy configuration
and diagnostics. STEP7 also allows upgrading already existing 1 SI CANopen boards
with this new functionality. Using the standard PROFIBUS or PROFINET bus
coupler of the ET200S, the 1 SI CANopen module can be used along with Siemens
automation and control systems.
HMS supports users of its 1 SI CANopen module with new PLC function
blocks which are used to create and analyze CAN 2.0A frames directly in the PLC
program. Based on these function blocks, PLC programmers can easily implement
customer specific CAN application protocols or specific CAN application
An in-depth survey of 700 current and future users of 3D printing holds few surprises, but results emphasize some major trends already in progress. Two standouts are the big growth in end-use parts and metal additive manufacturing (AM) most respondents expect.
