DynaControl V6 / Fieldbus Options
The V6 Fieldbus options allows any V6‐based unit to be monitored and controlled remotely.
Available options are:
‐ Profibus
‐ ProfiNet
‐ Ethernet/IP
‐ EtherCAT
‐ CC‐Link
Although those fieldbuses are different in several aspects, the data exchange between the remote
controller (typically PLC) and the hot melt equipment is always the same. The data exchange is based
on parameter tables (Input and Output Data).
The structure of the I/O tables allows easy access to commonly used information but also access to
more in depth parameters if required.
The first half of the I/O tables are used to exchange important:
Input:
‐ ASU control: on/off/Standby
‐ Pump control: on/off pump speed
‐ Local or remote access
Output:
‐ System Status: ready, heating, warnings, alarm etc.
‐ Pump status: Run, Hold, actual pump speed
‐ Level indication
‐ Pressure read out
Those parameters are directly accessible without special PLC logic.
The second half of the I/O tables are used for block transfer. The block transfer can be used to
exchange more detailed information. This is an on‐demand transfer and requires PLC code to manage
the transfer.
Following Blocks are available:
‐ Detailed system status
‐ Actual Temperature for each zone
‐ Read back of temperature set points
‐ Current temperature status
‐ Actual pressure for secondary transducers
‐ Temp. zone sequencing and zone on/off
‐ Pump speed manual setpoints
‐ Pump speed automatic scaling
‐ Pressure loop parameters
If parameters have to be changed that are not available within the predefined Blocks above, it is
possible to create custom blocks. With this it is possible to access virtually every internal parameter.
Since this requires special knowledge this is out of the scope of the standard documentation. If
required a special technical instruction sheet is available on request.
Local access vs. remote access:
Once the system is controlled via field bus, the fieldbus takes priority over parameter change via HMI.
In order to make local changes (on ASU’s HMI) possible the PLC can grant access to those
parameters. The access is separated into global control and Line speed control.
