CAN 2 system bus

X32:1 – X32:3

  • System bus CAN 1 and CAN 2 to CAN specification 2.0, parts A and B, transmission technology to ISO 11898
  • The CAN 2 system bus is electrically isolated
  • Max. 64 stations per CAN system bus
  • Max. 64 SCOM transmit objects / 32 receive objects per CAN system bus
  • Address range 0 - 127

Engineering

Engineering takes place via one of the following interfaces:

  • Ethernet 2 (X37)
  • In preparation: USB (X35)

Engineering for all SEW components connected to the MOVI-PLC®advanced DHE41B control card can be performed using the MOVI-PLC®advanced DHE41B control card.

Engineering of the MOVI-PLC®advanced DHE41B controller cannot be performed via the inverters.
