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.
Install the Gateway
Module Hardware
Location
Install the Gateway module near the EasyKey
™
, in a
non-hazardous area.
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
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.
This equipment is not for use in explosive atmo-
spheres. Do not install equipment approved only for
non-hazardous location in a hazardous area.
Your system must be grounded. Read Warnings,
page 4.
