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

3. Operational settings mode
The «operational settings mode» defines the following
CC-Link parameters:
CC-Link version
Number of occupied stations: The number of stations (occupying one stations worth of memory
area) used by a single slave station in a network.
Extended cyclic settings: In the extended cyclic transmission (only Ver.2), the extended cyclic
points can be 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’,
‘Universal Hyper Terminal’ or ‘Service Box 2’.
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.
«c:0100»
