Communication interfaces and modes

5.1. CC-Link overview

www.balluff.com
The BNI CCL-502-100-Z001 module supports both CC-Link Ver1 and CC-Link Ver2
communication forms. Ver2 is capable of transmitting greater amount of data using multiple
scan cycles (extended cycles).
Bus configuration is described by slave (station) address, number of occupied stations,
communication speed and -in case of Ver2 communication- number of extended cycles. All
of these are adjustable via the interactive display.

There are [Version, Number of stations occupied, Extended Cycle] settings stored in the
module, called presets, P0 to P5. User cannot change Number of stations occupied, Version
or Cycle Settings one-by one. User can only select which preset to use.
However, between limits given by the current preset selected, user can change some data
mapping settings. See section "Data mapping" for details.
