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 com- munication 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 regis- ters (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 communi- cation hardware on the PLC side.

Mounting
1.See Dimensions, page 79.
2.Ensure that the wall and mounting hardware are strong enough to support the weight of the equip- ment, cables, and stress caused during operation.
3.Using the equipment as a template, mark the mounting holes on the wall at a convenient height for the operator and so equipment is easily accessi- ble for maintenance.
4.Drill mounting holes in the wall. Install anchors as needed.
5.Bolt equipment securely.
Grounding
Your system must be grounded. Read Warnings, page 4.
The Gateway module is grounded through its connec- tion to the EasyKey, which must be connected to a true earth ground. See the system installation manual. A ground wire and clamp, part no. 223547, is available from Graco.
