Partlow Multi-Loop Controllers
MLC 9000 Bus Compatible PID Control
The MLC 9000 is a unique, stand alone PID control solution to use instead
of discrete DIN controllers.
The MLC 9000 is a unique PID controller that replaces PLC
PID-control and I/O cards.
- Reduce Wiring Costs
- Clean up the panel
- Simplified Interface, Fewer buttons to push
- Maintain Single Loop Integrity
The MLC 9000 simplifies single loop control by providing a single user
interface with access to all control loops. The cost of installation
is dramatically reduced by eliminating wiring, reducing the number of holes
that have to be cut into the panel, and reducing the overall panel size.
- PID control does not affect PLC processor speed.
- Lower per loop cost; only purchase the loops you need
- Fast, easy configuration
Configuration is accomplished via a windows based software program eliminating
the need to configure each controller individually and allowing programs
to be saved in simple recipe files. This ensures the integrity of
all control loops by making sure that multiple configurations are loaded
identically, accurately and quickly. A higher level of configuration
security can be maintained by eliminating configuration interfaces and
reducing operator access to sensitive configuration parameters.
Although the system is a multi-loop platform, the unique architecture
allows the system to maintain single loop integrity while offering "hot
swap" and auto-configuration capability for each loop.
The MLC 9000 System is a complete PID control system with individual
controllers connected together via an internal communications bus. Controllers
use advanced PID, self tuning and Fuzzy Logic algorithms to provide tight
control of system PID loops. The MLC system can communicate with other
devices via various industrial communications protocols.
BCM - The Bus Communication Module...
contains an on board microprocessor to handle all system and network communications
for the individual controllers. The BCM also stores a backup copy of the
configurations for each individual controller module. When an individual
controller module is changed, this backup copy is automatically downloaded
to the new unit. Industry standard protocols such as DeviceNet, Profibus
and MODBUS are available to allow transfer of PID control and process data
from the individual controllers to other external devices. Up to 32 BCM
units can be connected together via a two wire system.
LCM -The Loop Controller Module...
is an independent PID controller. There can be up to 8 LCM’s per BCM Module.
By daisy chaining BCM’s, up to 256 controllers can be connected to a single
node. The LCM contains all process control capabilities as well as all
input and output connections. Each individual LCM can be removed and replaced
while the system is under power.
LIM - The Loop Interconnect Module...
allows for a "building block" approach to system assembly so the user only
purchases the number of loops required for the application. Individual
loops can be removed without affecting the performance of other modules
in the system. In addition, the LCM design enables individual loop integrity
to be maintained and also has the added benefit of allowing auto-configuration
and hot-swapping of each individual module as described above.
