BIS V-6111 CC-Link
Processor unit
7 english
The processor unit is the link between data carrier and controlling system. It manages two-way
data transfer between data carrier and R/W head and provides buffer storage.
The processor unit uses the read/write head to write data from the controlling system to the data
carrier or reads the data from the carrier and makes it available to the controlling system.
Controlling systems may be the following:
– A control computer (e.g. industrial PC).
– A PLC.
In order to increase data integrity, data transfer between the data carrier and processor unit and
the storage device must be monitored using a check procedure.
A CRC_16 data check can be enabled for this via parameter configuration.
With the CRC_16 data check, a check code that allows the validity to be checked at any time is
written to the data carrier.
A CRC_16 data check provides the following advantages:
– Data integrity even during the non-active phase (data carrier outside the R/W head).
– Shorter read time – page is read once.
For BIS V-6111-073-C003, read/write heads of the BIS VM-3… and BIS VL-3… series can be
connected to terminals H1…H4.
BIS V-6111-073-C103 also supports read/write heads of the BIS C-3… series (adapter
required).
Connecting the read/write heads only using shielded cables is recommended for compliance
with the EMC Directives.
The maximum cable length for read/write heads of the BIS VM-3… and BIS VL-3… series is
50 m. Depending on the system design, the cable length for the BIS C-3… series is set to 1 m,
5 m or 10 m plus adapter.
Open bus system for process and field communication. Automation devices, such as PLCs,
PCs, operating and observation devices, sensors or actuators, can communicate using this bus
system.
