Product description Flexi Soft
gateways
Further information about the properties, functions and benefits of the EFI interfaces can
be found in the Flexi Soft Hardware operating instructions (SICK part no. 8012999).
The general EFI function description is available in the operating instructions “EFI -
Enhanced Function Interface” (SICK part no. 8012622).
3.3.4
Routing of data from a second network
If your Flexi Soft system contains two gateways, it is possible to rout information received
by the first gateway from one network (e.g. from a Modbus PLC) into a second network via
the second gateway (e.g. to a PROFIBUS master) and vice versa.
3.3.5
Configuration checksums (CRCs)
Data set 2 contains the following configuration CRCs for the Flexi Soft system:
overall CRC (same as system CRC). The overall CRC is the checksum displayed in the
Flexi Soft Designer report.
system CRC (SCID)
verified configuration CRC. If this value is identical to the System CRC, the configuration
is verified. Otherwise the configuration is not verified.
Each checksum is four bytes long. Data set 2 can not be customized.
3.3.6
Error and status information of the modules
Data set 3 contains the module status information transferred to the network.
Four bytes are transferred for each module (e.g. FX3-XTIO). Data set 3 can not be
customized.
Reserved (for future use) = static 1 (no status change)
If no module is present, all values including the reserved values are set to logical 1.
The four status bytes for each module are being transferred in Big Endian format as
32 bit word, i.e. the most significant byte (MSB = byte 3) is transferred first and the
least significant byte (LSB = byte 0) is transferred last.
