ESD CAN-CBM-SIO4 I/O Controller - 1x CAN 2.0A/B at (4+1) x RS-232, RS-232, -422, -485 or TTY to CAN, Compact top-hat rail module Simple Type: I/O Controller

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. 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. 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.
