Grundfos Control MPC

The Grundfos Control MPC is a multi-purpose controller that will work with Modbus RTU (CIM 200), Modbus TCP (CIM 500), UDP/IP BACnet and MSTP BACnet. (MSTP BACnet only if used on foreign networks to which you connect via IP)

A selection of models is available for both the Modbus profile and the BACnet profile.

This one tag contains the child tags needed to run the system in any of the standard closed-loop operating modes (pressure, temperature, flow). Additional child IO tags can be added to match the exact sensor configuration, where they will display on the inputs tab.

Grundfos Control MPC: Settings tab

 

Units

The device may be used for a variety of control modes, covering measurement of flow, temperature, and pressure. Use this to ensure that the display matches the purpose of the controller and your preferred system of units.

Number of Pumps

Select a number from 0 to 6, matching your system.

Import GENIBus Comms

Enable to view GENIbus communications for detecting problems between the controller and the pumps.

Alarm Simulation

Enable to use the alarm simulation tool in the controller. This will be added to the Summary tab of the automatically-generated station page. To enable the Start button, provide an alarm code in the space provided.

CIM Settings

Enable to view and edit the CIM card settings (Communication Interface Module). Needed only for configuration.

Import Grundfos Version Information

Enable to display Grundfos-specific information on the inputs tab.

Pilot Pump

Select this option if the system contains a dedicated pilot pump for its controls.

Backup Pump

Enable if the system contains a dedicated backup pump for its controls

Tank Filling Application

Enable if the controller is configured for a tank-filling application, in order to allow access to the extra setpoints that are needed.

Control Privilege

Select a custom security privilege (Protect Pages and Output Tags) from this drop down to limit the operation of this control to only those operators who have been granted the matching security privilege.

Port

Select the TCP/IP or Serial Port tag that is to be used for communication with the equipment. The ancestor port is selected automatically if this tag is created as a child of a port.

Station Number (Poll Sequence)

Used by the built-in Polling Driver Tags. Use the Poll Sequence Number field to specify a number that identifies this polling driver's place in the polling sequence for the identified poll group.

For example, if you have 5 polling drivers, each of which is associated with a different communication driver (e.g. Modbus1, Modbus2, etc.), and all 5 polling drivers have the same poll group identified (in their Poll Group Name property), you must enter a number from 1 to 5 for each of the polling drivers to determine the order in which the 5 communication drivers belonging to the poll group will be polled.

Scan Interval

Used by the built-in Polling Driver. The amount of time (in seconds) between requests for data from this Polling Driver tag to the I/O device with which it is associated.

CIM Model

Choose between models CIM 200, CIM 250 GSM, CIM 250 GPRS, CIM 300, CIM 500 Modbus or CIM 500 BACnet.

Driver

Configured automatically in response to your choice of CIM model.

Comm Channel (Modbus compatible profile)

Serial RTU, Open Modbus TCP/IP or Open Modbus TCP

PLC Address (Modbus compatible profile)

The standard port is 231, but may be overridden if necessary.

Network Type (Routing) (BACnet profile)

Set automatically based on your selection of CIM model

Device Node and Device Network Number (BACnet profile)

When operating in foreign network mode of BACnet, specify the network number that the device is on, and specify the device node number on that network.

Time-Out Limit

Set the receiver time-out limit in seconds or fractions of a second. This is the length of time that this driver should wait for a reply from the PLC or RTU.

I/O Driver Override (optional)

The device typically uses a built-in Modbus Compatible Device Driver, or BACnet Driver based on your choice of CIM, but you may use this tool to select another.
