For PCU100 (PCU) specifications and installation information, refer to datasheet (MAN0432). See
Technical Support section in this document for manual updates and assistance.
1 Product Overview
The Printer Control Unit (PCU100)…
• Is a low cost solution that allows you to collect, store and track data (up to 25 hours) and
print data Trend Reports without costly HMI units or chart recorders.
• Comes conveniently pre-programmed to record and print four standard types of data trend
measurements that are commonly used in business and industry: Pressure, Flow Rate,
Temperature and Level trends.
• Allows fast, easy creation of OCS interface using pre-programmed controls.
• Connects to any Hewlett-Packard printer with IEEE 1284 parallel port and that uses PCL3
such as HP Deskjet 5650.
• Provides customized reports such as alarm or industry-specific reports - available for additional
cost by contacting Horner Sales staff.
An example of a data trend report is on the last page of this document.
2 Configuration Overview
2.1 Brief Summary of Steps to be Taken
The following steps must be done to configure the PCU. They are covered in detail later in this section.
1. Setup equipment including the PCU, Hewlett Packard printer, cable, and Master Controller (Horner
Operator Control Station [OCS] in our example).
2. Configure the OCS to interface with the PCU via the CsCAN network.
3. Build a ladder program in the OCS to interface to and control the PCU.

2.2 Equipment Setup / Network
• Interaction with the PCU100 (PCU) requires a OCS. Although the PCU does not have a local
operator interface, it does support a remote operator interface through an OCS over a CsCAN
network.
• As shown in Figure 1, the PCU is connected to a Hewlett Packard (HP) printer with the cable that
comes with the PCU. The cable connects the PCU to any Hewlett-Packard printer with IEEE
1284 parallel port and that uses PCL3 or greater.
Note: Our example uses one PCU, but multiple PCUs can be connected to the CsCAN network.
Figure 1 - PCU Setup in a CsCAN Network
2.3 Interface Configuration Software
Cscape software is used to interface the PCU to the OCS over a CsCAN network.
2.4 Ladder Programming
You need to build a ladder program (subroutine or sequence) that uses NETPUT and NETGET to
configure and control the PCU. Examples of ladder code programs are shown in Figures 3 through 6.
Also, refer to Tables 1 through 2.

3 Configuration Procedure
1. Interfacing the PCU via the Master Control (OCS in this example)
NOTE: The Network Baud Rate of the PCU unit is set to 125K.
The controller portion of OCS products is programmed in ladder logic via the Windows-based Cscape
(Control Station Central Application Programming Environment) package.
a. Run Cscape and establish a connection to the Master OCS. The default screen appears.
b. At the top of the menu bar, click on the Program tab.
c. Select Network Config from the pull-down menu.
d. Click the Option tab. The following Network Configuration screen appears:
Figure 2 – Network Configuration Screen
e. Click the Network Required box to the other network options.
f. Click the Network Optimized box to speed network transfers.
g. Fill in the Number of Network IDs required by the Master OCS. (Minimum number is 4 to support
one PCU). Enter 17 or more in the Max Packets per Scan box to enable all packets to be transferred
each scan (1 – 32 packets).
h. Press OK.

2. Build Ladder Code
a. Write Ladder Code to support the register assignments described in Tables 1 and 2. Example ladder
code is located after the tables.

b. The following are examples of ladder code built off of the register assignments in Tables 1 and 2.
Refer to the comments on each ladder code figure as they step you through the code and relate it
back to the register assignments in the Tables 1 and 2.
Note: For all ladder code examples, the Master OCS uses ID 1 through 4. The PCU uses
default ID 10.
You need to build a ladder program (subroutine or sequence) that uses NETPUT and NETGET to
configure and control the PCU. Examples of ladder code programs are shown in Figures 3 – 6.

4 Operation Including Print Trend Report
Note: The following procedures reference the above example, which uses data in Table 1 and
Table 2 and Ladder Code Figures 3 – 6.
1. Apply the quantities to be measured from %AI1 through %AI4.
(This references Pressure, Flow Rate, Temperature and Level quantities.)
2. Set %M1 through %M4 to zero.
(This references interface controls Print Trend, Cancel Print, Store Data, Clear Data.)
3. Set %M5 as desired for the sample rate.
(This references the Scale Range, which indicates the time interval that each sample occurs.)
4. Enter the customer name, job number, and purchase order information including their respective
lengths in %R1 through %R60.
5. Set %M3 (Store Data) to 1 to enable data capture. Allow the network application to run until the
desired number of sample intervals has passed.
6. Clear %M3 to zero to stop data acquisition.
7. Set %M1 to print the trend report. (Set at least one second.)
8. Clear %M1 to zero.

PAGE 8 19 APR 2005 MAN0790-01
9. %M4 can be momentarily set to one and then cleared to erase the stored data in the PCU and
prepare the PCU for a new capture and trend print cycle. (Set at one second to clear.)
10. %M2 can be momentarily set to one and then cleared to cancel a print in progress. (Set to be on
for one second.)
5 SAFETY
All applicable codes and standards need to be followed in the installation of this product.
When found on the product, the following symbols specify:
For detailed installation and a handy checklist that covers panel box layout requirements and minimum
clearances, refer to the hardware manual of the controller you are using. (See the Additional
References section in this document.)
• For I/O wiring (discrete), use the following wire type or equivalent: Belden 9918, 18 AWG or
larger.
• Adhere to the following safety precautions whenever any type of connection is made to the
module.
• Connect the green safety (earth) ground first before making any other connections.
• When connecting to electric circuits or pulse-initiating equipment, open their related breakers. Do
not make connections to live power lines.
• Make connections to the module first; then connect to the circuit to be monitored.
• Route power wires in a safe manner in accordance with good practice and local codes.
• Wear proper personal protective equipment including safety glasses and insulated gloves when
making connections to power circuits.
• Ensure hands, shoes, and floor are dry before making any connection to a power line.
• Make sure the unit is turned OFF before making connection to terminals. Make sure all circuits
are de-energized before making connections.
• Before each use, inspect all cables for breaks or cracks in the insulation. Replace immediately if
defective.
Warning: Consult user documentation. Warning: Electrical Shock Hazard.
WARNING: To avoid the risk of electric shock or burns, always connect the safety (or earth)
ground before making any other connections.
WARNING: To reduce the risk of fire, electrical shock, or physical injury it is strongly
recommended to fuse the voltage measurement inputs. Be sure to locate fuses as close to the
source as possible.
WARNING: Replace fuse with the same type and rating to provide protection against risk of
fire and shock hazards.
WARNING: In the event of repeated failure, do not replace the fuse again as a repeated failure
indicates a defective condition that will not clear by replacing the fuse.
WARNING: Only qualified electrical personnel familiar with the construction and operation of
this equipment and the hazards involved should install, adjust, operate, or service this
equipment. Read and understand this manual and other applicable manuals in their entirety
before proceeding. Failure to observe this precaution could result in severe bodily injury or
loss of life.
