The CAN 400 module from the Systeme Helmholz GmbH for use in a S7-4001) from Siemens permits connection of CAN stations with the programmable controller. The module can be slotted either into the central controller or into the expansion unit. The CAN 400 modules support both CAN 2.0A (11 bit) and CAN 2.0B (29 bit) frames with a free selectable baudrate of 10 Kbit/s to 1 Mbit/s. Technical Data Dimensions (LxWxH mm) The CAN 400 module can also be run as Layer 2, CANopen Master, CANopen Slave and with Lenze System bus. The CAN 400 module contains the scripts „Power On“, „Stop -> Run“, „Run-> Stop“, „Power Off“. IDs relevant to the programmable controller can be prefiltered using a 5level acceptance mask. In CAN 400 modules, 16 free settable timers up to a resolution of 1ms are available. Each timer can trigger a free programmable CAN frame. In that way, it is simple to implement synchronous protocols commonly used in drive and servo control using the CAN 400 module.
