Pass Through Program User Manual
1 INTRODUCTION
1.1 Scope and Organization
This document serves as the user manual for the Pass Through program (QER 05Q045), which is
intended for use in the ROC800-Series Remote Operation Controllers (“ROC800s”). This manual
describes how to download, install, and configure the Pass Through user program (referred to as the
“Pass Through program” or “the program” throughout the rest of this manual). You access and configure
this program using ROCLINK 800 Configuration Software loaded on an IBM-compatible personal
computer running Windows 98, NT 4.0 (with Service Pack 6), 2000 (with Service Pack 2), or XP.
The sections in this manual provide information in a sequence appropriate for first-time users. Once you
become familiar with the procedures and the software, the manual becomes a reference tool.
This manual has the following major sections:
Section 1 – Introduction
Section 2 – Installation
Section 3 – Configuration
Section 4 – Reference
This manual assumes that you are familiar with the ROC800s and their configuration. For more
information, refer to the following manuals:
ROC809 Remote Operations Controller Instruction Manual (Form A6116).
ROC827 Remote Operations Controller Instruction Manual (Form A6175).
ROCLINK 800 Configuration Software User Manual (Form A6121).
1.2 Product Overview
The Pass Through program enables host programs to send and receive messages from other devices
through the host’s connection to the ROC800. This pass-through feature supports host messages coming
in through Ethernet or serial connections and then passing back out through another Ethernet connection
or through different serial connections. Essentially, this means you can route requests from highbandwidth (Ethernet-based) devices to low-bandwidth (serial-based) devices and back again. The
program also provides a method to convert serial and Ethernet messages passing to and from devices
attached to different physical connections.
For example, a host is connected via Ethernet to a ROC800. A FloBoss 407 is physically connected
serially to the same ROC800. The Pass Through program enables the host to pass a message through the
ROC800 to the FloBoss 407 via the serial connection. This can be especially useful for remote
connections to ROC300-Series, FloBoss 100-Series, FloBoss 500-Series, FloBoss 407s, Modbus slave
devices, or other ROC800s.
Note: The ROC Protocol limits the total number of serially-connected devices you can manage. Refer
to the ROC Plus Protocol Specification Manual (Form A6127) for further information.

Pass Through Program User Manual
To accomplish this pass-through functionality, you complete the parameters on the Pass Through
configuration screen, identifying the communications port the host connection and the slave
connection(s) use.
Note: In addition to routing host requests through Ethernet-connected to serially connected flow
computers or ROCs, you can also enable the routing ROC to respond to the host request using the
industry-standard internal loopback address of 127.0.0.1:4000. Since this program, by default, passes
through all messages, it does not allow the ROC800 to “monitor” and then respond to messages
intended for itself. However, you can configure the program to route incoming messages to the internal
loopback address, which enables the ROC800 to respond to incoming Ethernet messages addressed to
itself.

Figure 1. Pass Through Environment
Figure 1 shows how remote serial devices might be connected to a host using the Pass Through program.
In this example, the host connects to the ROC800s (ROC1, ROC2, and ROC3) via Ethernet. The Pass
Through program is located on each ROC800. Host requests come to port 5000 of the ROC800s and are,

Pass Through Program User Manual
in turn, sent out to the appropriate serial or Ethernet ports according to the configuration of the Pass
Through program.
The Modbus device, the FloBoss 503, and the FloBoss 407s connect to the ROC800s using either a
serial connection or a radio connection. Without the Pass Through program, they cannot respond to
requests from the host. Once both the host and the Pass Through program are configured correctly, these
devices can communicate with the host.
Note also that ROC3 uses the internal loopback address (127.0.0.1:4000) in order to respond to requests
from the host. This would not typically be the way the host is configured, since ROC3 would probably
be polled directly on port 4000. However, this loopback example is provided to illustrate this
functionality.
Note: Refer to Appendix A in the Protocol Driver Host Program User Manual (Form A6201) for more
information in using the Pass Through program in conjunction with the Protocol Driver Host program.

1.3.1. License Keys
License keys, when matched with valid license codes, grant access to applications such as the Run
Switching program.
The term “license key” refers to the physical piece of hardware that can contain up to seven different
licenses (refer to Figure 1). Each ROC800 can have none, one, or two license keys installed. If you
remove a license key after enabling an application, the firmware disables the task from running. This
prevents unauthorized execution of protected applications in a ROC800.

2 INSTALLATION
This section provides instructions for installing the Run Switching program. Read Section 1.3 of this
manual for program requirements.
2.1 Installing the License Key
If you order the Pass Through program for a new ROC800, your ROC800 is delivered with the license
key installed. Go to Section 2.2.
If you order the program for an existing ROC800, you must install the license key yourself.
Failure to exercise proper electrostatic discharge precautions—such as wearing a
grounded wrist strap—may reset the processor or damage electronic components,
resulting in interrupted operations.
When working on units located in a hazardous area (where explosive gases may be
present), make sure the area is in a non-hazardous state before performing these
procedures. Performing these procedures in a hazardous area could result in personal
injury or property damage
To install a license key:
1. Remove power from the ROC800.
2. Remove the wire channel cover.
3. Unscrew the screws from the Central Processing Unit (CPU) faceplate.
4. Remove the CPU faceplate.
5. Place the license key in the appropriate terminal slot (P4 or P6) in the CPU (refer to Figure 2).

6. Press the license key into the terminal until it is firmly seated (refer to Figure 2).
7. Replace the CPU faceplate.
8. Replace the screws on the CPU faceplate.
9. Replace the wire channel cover.
