Graco Gateway Overview

The Graco Gateway enables the ProMix 2KS to network with a programmable logic controller (PLC). Kits are available for Ethernet, DeviceNet, or Profibus protocols. The Graco Gateway will support many other protocols; contact Graco Technical Assistance for information to support your desired protocol.

NOTE: Only persons very familiar with their PLC communication architecture should use this hardware and software. This manual assumes that the person using the Graco Gateway has full understanding of the PLC equipment and related software.

NOTE: Network communications essentially operate with the same rules as Discrete I/O. However, network communications require placing correct values or adjusting appropriate bits within various Modbus registers (for example, see Table 4). These changes should only be made by qualified persons familiar with this type of communication.

The module allows for most PLCs to communicate with the ProMix 2KS via Modbus RTU protocol by bridging the gap between the desired communication protocol and RS485 Modbus RTU. As a result, the PLC has full access to all the registers for monitoring and controlling the ProMix 2KS. It is the responsibility of the integrator or user to ensure proper configuration of the communication hardware on the PLC side.

Modbus and I/O Data

Modbus and I/O Data

See Table 4 through Table 5 for Modbus register addresses and input/output data.

Reference the Discrete I/O listing of all the inputs and outputs (see page 30). Ensure these are fully understood. The same implementation used for Discrete I/O is used for the Network communication protocol.

For example: The Gun Trigger Input will now be a specific bit of Modbus Register 40040. Monitoring of Modbus Register 40041 for specific output status conditions will be required as explained in the Discrete I/O section of the ProMix 2KS Operation manual. The PLC will have to read the various bits, and in some cases (40040 and 40041 for example) must mask out the various bit positions to determine each of the separate input and output statuses. This requires experience and should not be done on the job site. A full understanding of the color change process as well as the required timing of various inputs and outputs is required.

NOTE: Analog input for flow control set point will now be a dedicated Modbus register. Register 40137 will require the specific flow rate (i.e. 125 cc/min). This is not a voltage reading but the actual flow target.

Start Mix Process

See FIG. 25, Table 1, and Table 2.

1.Verify that the Mix Ready bit (bit 2 of 40041) is on.

2.Turn on the Mix bit (bit 7 of 40040).

3.Verify that the Mix Active bit (bit 1 of 40041) is on, to ensure that the Mix request was received.

Stop Mix Process

See FIG. 26, Table 1, and Table 2.

1. Clear the Mix bit.

2.The Mix Active output should clear and Mix Ready should now be set.

NOTE: The ProMix 2KS will automatically go into Idle mode after 2 minutes of inactivity. A general alarm will be present and Mix Active will remain High. The Alarm bit (40010) will indicate the system Idle alarm. When a new Gun Trigger input is seen, the ProMix 2KS will resume mixing material where it left off. Do not toggle the Mix bit; doing so restarts the Mix process from the beginning.

Color Change Process

See FIG. 28, Table 1, and Table 2.

1.Verify that Mix Ready is set. This ensures that there are no alarms and that the system is ready for the next command.

2.Load ccNewRecipe (Modbus 40046) with a recipe number to color change to.

3.Set color change (40040 bit 6).

4.Verify that Purge_CC_Active is seen (40041 bit 0).

5.Clear color change bit (momentary only).

6.Do not change the ccNewRecipe value until a new recipe change is requested.

7.The color change process will stop automatically as programmed. Monitor Purge_CC_Active bit for completion.

Purge Process

See FIG. 27, Table 1, and Table 2.

1.Verify that Mix Ready is set. This ensures that there are no alarms and that the system is ready for the next command.

2.Set purge (40040 bit 8).

3.Verify that Purge_CC_Active is seen (40041 bit 0).

4.When Purge_CC_Active bit clears, clear Purge_Start bit. Clearing this bit in the middle of a purge sequence will abort the purge sequence.
