2. Transmission rate
Use the same «transmission rate» for all stations in the bus and also for master station. If any of the settings for at
least one station is different, data link cannot be established normally.
The «transmission rate» can select from 156 kbps / 625 kbps / 2.5 Mbps / 5 Mbps / 10 Mbps
The «transmission rate» can be configured by 'Control View', 'Control Performance Analyzer' or 'Universal Hyper Terminal.
The «set-command» is: «s:21xxx00000». The xxx value is the «transmission rate» shown in the table below
The «get-command» is: «i:21». The answer returns the «transmission rate»  «i:21xxx00000». The xxx value is the
current «transmission rate».
Consider that the controller must be in local mode to accept the commands! After a s:21 command is sent the module is
reseted and starts up again.
«c:0100»  change into local mode
«c:0101»  change into remote mode

by a single slave station in a network.

set as 2 times, 4 times or 8 times of the normal cyclic transmission points.
The VAT slave supports two combinations of the CC-Link parameter settings.
Value Operational settings
001 CC-Link Ver.2 / Occupies 1 station / Octuple expanded cyclic
004 CC-Link Ver.2 / Occupies 4 stations / Double expanded cyclic
The «operational settings mode» can be configured by 'Control View', 'Control Performance Analyzer' or 'Universal Hyper
Terminal.
The «set-command» is: «s:22xxx00000». The xxx value is the operational settings mode!
The «get-command» is: «i:22». The answer returns the «operational settings mode»  «i:22xxx00000». The xxx value is
the current operational settings mode.
Consider that the controller must be in local mode to accept the commands! After a s:22 command is sent the module is
reseted and starts up again.
