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.

• Reduce Wiring Costs 
• Clean up the panel 
• Simplified Interface, Fewer buttons to push 
• Maintain Single Loop Integrity 

• 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.
