Control and status bytes
Communication via the fieldbus takes place via 8 control and
status bytes. Functions and status messages required during
operation can be controlled directly – mostly with single-bit
operations.
Record Select
The Record Select mode can be used to execute position set
records saved in the MTR-DCI.
For this purpose, up to 31 position sets are parameterised
during commissioning either using the Festo Configuration
Tool or taught via the control panel.
Direct mode
In the Direct mode the important positioning data are trans-
ferred directly via the control bytes.
– The controller can determine and specify target positions
and speeds according to the current operating status,
during running time. No limitation is imposed by the
number of saved position set records.
– Alternatively, a torque (or force) can be specified relative
to the nominal motor current, which the MTR-DCI needs
to apply.
Festo Parameter Channel (FPC)
The parameter channel lets the higher-order controller access
all parameter values of the controller via the fieldbus.
A further 8 control and status bytes are used for this purpose.
