Intelligent Interface between CAN and Serial Interface
The CAN-CBM-SIO4 module offers the connection between five serial
interfaces and the CAN network with intelligent data management (CBM-SIO1 just
one serial interface). It operates with a 68331 microcontroller, which buffers
the CAN data in a local SRAM. Data security and consistency are guaranteed up
to 1 Mbit/s in the CAN network. The firmware - including optional protocols –
is stored in the Flash.
CAN Interface
The ISO 11898-compliant CAN interface allows a maximum
data-transfer rate of 1 Mbit/s. The CAN interface is electrically insulated by opto-couplers
and DC/DC converters. Connection is via a 5-pole connector with screws or via
DeviceNet.
Serial Interfaces
You can configure all interface parameters through CAN - the
maximum bit rate is 500 Kbit/s (RS-232: 38, 4 Kbits). The parameters and CAN settings
are stored in an EEPROM. In standard mode without protocol, the unit transmits
a CAN frame on the previously set CAN identifier after receiving 8 ASCII characters
or a configurable end character (e.g. CR, LF or EOT) and after a definable time
out ran out when no characters have been received anymore.
Alternatively, usual protocols, such as 3964R, Modbus and FreePort
are available for the connection of an S7-200. Customized protocols are
available on request or developed by means of GNU-C. When using the RS-232
interface as a modem connection, a remote service is available for the CAN
network in remote operation.
Apart from RS-232, it is also possible to choose RS-422, RS-485,
or TTY-20mA as physical interfaces. The connection of the serial interface is
through four RJ45-sockets (only at CBM-SIO4) and one DSUB9-connector.
CAN Protocols
At your request, CANopen and DeviceNet can be supported as layer-7
protocols on CAN side.
