Loading the HEC-P6XXX Kernel
The kernel is the rmware for the controller and to provide greater exibility and reliability, HEC Controller shipments are factory
shipped without a kernel. If this is a new unit from the factory, it will be necessary to load the kernel before a ladder program can
be downloaded. If the kernel is already loaded, this step is not required. To upgrade a kernel, see the P-Series EZ LADDER Toolkit
Manual.

Geng to Know the HEC-P6XXX
The HEC-P6XXX Controller is designed to provide powerful programmable features in a tough, harsh environment resistant package.
The main features of the HEC-P6XXX are accessed via four (4) sealed Deutsch connectors that will be referred to as the ‘A’ connec-
tor which is grey, the ‘B’ connector which is black, the ‘C’ connector which is green and the ‘D’ connector which is brown.
Each HEC connector is a Deutsch sealed connector with 12 connecons each. The mang connectors for the HEC-P6000 are sold
separately. Connectors may be purchased as kits (HEC-P10, HEC-P20, HEC-P30 and HEC-P40) or cable assemblies may be purchased
with the mang connectors pre-wired with ying leads on one end (HEC-P100, HEC-P110, HEC-P120 and HEC-P130). In addion to
connectors and kits for standard wiring, programming break-out cable assemblies may be purchased (HEC-P910).
The HEC-P6000 front connector is a Deutsch DT13-48PABCD-R015 that includes the keyed A, B, C and D connecon points. The
following Deutsch connectors are recommended as the plugs for the HEC-P6XXX controller if purchased from other sources. Other
connectors are available. Consult Deutsch documentaon for other compable connectors.
A connector: DT06-12SA-B016
B connector: DT06-12SB-B016
C connector: DT06-12SC-B016
D connector: DT06-12SD-B016
Wedge Lock: W12S
Addional items (wedge locks and crimp pins) and a crimping tool will be required. Crimp pins vary based on the size of wire and
crimping devices available.
Refer to Figure 1.5 for the HEC-P6XXX connectors A, B, C and D front view Pin Assignments.
Figure 1.6 illustrates the HEC-P6XXX controller and it’s standard features.

HEC-P6XXX Conguraon Jumpers, Switches and Potenometers
To gain the most value of the many features included in the HEC-P6XXX controller, there are many opons that may be congured
in the eld for actual needs. These opons are congured using the internal conguraon dip switches and jumpers. To congure
these switches and jumpers, the HEC-P6XXX must be dis-assembled.
There are three 4 posion slide switch blocks, idened as SW1-SW3 and SW6. Each block contains 5 individual switches that are
used to congure opons. When the switch is in the ON posion, it is closed. In addion to the (4) 5 posion slide switch blocks, 2
addional single switches are included, SW4 and SW5. 3 Posion jumper blocks are also provided for conguraons. There are also
2 potenometers for adjusing the analog outputs.
Figure 1.8 shows the locaons of the switches and jumpers when the HEC-P6XXX has been opened. Figure 1.9 shows the dierent
switch and jumper conguraons.

HEC-P6XXX Features
Programming Port
The HEC-P6XXX is programmed using its Programming Port (COM 0). This RS232 serial port is only to be used for
programming using Divelbiss EZ LADDER Toolkit soware. This is not a general purpose port and may not be used in any
other capacity than programming the controller itself. The baud rate is factory set and cannot be changed between the
HEC-P6XXX and EZ LADDER Toolkit.
The HEC-P6XXX Programming Port is wired through the A Connector using pins 2, 3 and 4. The Programming Port requires
a NULL MODEM cable or connecon to the computer to establish communicaons between EZ LADDER Toolkit and the
HEC Controller. Figure 2.1 represents a direct wiring connecon from the PC to the HEC-P6XXX controller. The HEC-P910
programming break-out cable is an in-line cable that allows for programming connecons while sll connecng the A
connector and eld devices (as shown in Figure 2.2). 

HEC-P6XXX Features
Status (STS) LED
The operang status of the HEC-P6XXX can be determined the by Status LED. When the Status LED is ashing at a slow
rate, approximately once per second, then there is no ladder program execung. When the Status LED is ashing at a fast
rate (several mes per second), a program has been loaded and it is execung.
If the Status LED appears to be ickering at a very fast rate, the Kernel is not running. Either the kernel needs to be installed or the
controller reset to restart the kernel if it is installed.
Should the Status LED not ash at all, rst check the input power. If the input power is correct and there is sll no Status LED,
contact Divelbiss Technical Services.
Power (PWR) LED
The HEC-P6XXX provides a power green status LED that can be seen from the front of the unit. When this LED is
illuminated, the input power should be sucient for the HEC-P6XXX to operate. If the LED is not illuminated, the input
power is too low for operaon.
Programmable LEDs (I1 / I2)
The HEC-P6XXX includes two user programmable LED indicators (labeled I1 and I2). These indicators are controlled in the ladder
diagram program by the variables PLED1 and PLED2 respecvely. These indicators may be used to idenfy any number of condi-
ons of the HEC-P6XXX controller or applicaon.
User Programmable Switches
The HEC-P6XXX includes two user programmable switches that are accessed in the ladder diagram as digital inputs as USER_IN1
and USER_IN2. These boolean variables are automacally created when the HEC-P6XXX target is selected. These switches may be
used to idenfy any funcon in the applicaon based on programming.
Input Power
The HEC-P6XXX may be powered using 8-32VDC. The power is connected on the ‘A’ (Grey) connector using pins 1 (+V)
and 2 (-V/Common). The power connected to these pins should be of sucient current to source power for the controller
logic, communicaon ports, analog and counter inputs. A typical input power wiring diagram is shown in Figure 2.3.
Source power for the inputs is divided into two groups of ve (5) inputs. Each group may be congured for sinking or
sourcing and thus each group has an individual common pin that must be connected separately from the main controller
power.
Source power for the outputs is divided into three groups of four (4) and 1 group of two (2) outputs. Each output group
has an individual power source pin that must be connected separately from the main controller power. While all the out
put power pins are separate from the main controller power, the output common (ground) for all connected loads must
be connected to the same common (ground) connected to pin 2 of the main controller power. Failure to do this could
result in unwanted operaon or even damage the HEC-P6XXX controller.

HEC-P6XXXHEC-P6XXX
The power connected to the main logic power input of pins 1 and 2 on connector ‘A’ may be monitored in the ladder diagram
program. This input power is oponally connected to analog input 7 (AN7). The conguraon switches SW3-3 must be set to ON
and SW3-4 must be set to OFF for the power monitor to funcon. Refer to the HEC-P6XXX Conguraon Jumpers, Switches and
Potenometers secon of this manual for switch locaons.
When congured as the power monitor, the actual voltage is measured and is available in the ladder diagram program using
variable AN7. AN7 is represented as an integer number and some logic must be added to the ladder diagram program to actually
convert this raw analog value into volts. Figure 2.4 is an example ladder diagram program to convert AN7 into volts.
AN7: Power Monitor Analog Input (Integer) - Automacally created
R_AN2: Variable used to store converted value of AN7 as a real variable type. This is required for calculaons.
R_Temp: Variable used to temporarily store values (real variable type) during calculaons.
AinScale: Variable used to store maximum analog input scale value (real variable type).The default value = 4095.0
MaxScale: Variable used to store the maximum input voltage scale (real variable type). The default value = 40.0
InputV: Scaled analog input represenng Input Voltage (real variable type)
Input Power Monitor
Note: Analog input 7 may be oponally congured to either be the input voltage to the controller (power monitor) or the
load current feedback from digital output 9 (DOT9 / PWM9). The actual conguraon is dependent upon how SW3-3 and
SW3-4 are set.

HEC-P6XXX Features
Mounng
The HEC-P6XXX controller is designed to be panel mounted directly into most environments. The HEC-P6XXX mounts using 4 screws
up to 1/4” in diameter. Even though the HEC-P6XXX can be submerged up to 3 meters in water, ideally, when mounng the HEC-
P6XXX controller, the end with the connectors should be mounted downward as to promote moisture ow away from the connec-
ons.
Figure 2.5 illustrates the HEC-P6XXX mounng hole locaons and unit dimensions.
Digital Inputs
The HEC-P6XXX includes up to 14 on-board digital inputs. They are idened in EZ LADDER Toolkit and this manual as DIN0 through
DIN13. The digital inputs are divided into four groups. Each digital input will operate from 8VDC to 32VDC.
DIN0 - DIN2 (variables DIN0 - DIN2)
These three (3) inputs may be used individually as digital inputs or as high speed counter inputs. These inputs may be cong-
ured as NPN or PNP inputs based on the conguraon switches of SW1-1, SW1-2 and SW1-3. When congured as NPN, these
inputs are pulled to the input power voltage.
DIN3 - DIN5 (variables DIN3 - DIN5)
These three (3) inputs may be used individually as digital inputs or together as a quadrature input. These inputs may be
congured as NPN or PNP inputs based on the conguraon switches of SW1-4, SW1-5 and SW2-1. When congured as NPN,
these inputs are pulled to the input power voltage.
DIN6 - DIN10 (variables DIN6 - DIN10)
These ve (5) inputs are dedicated as digital inputs only. This group has it’s own common pin, allowing this enre group to be
congured as sinking or sourcing based on the wiring.

HEC-P6XXX Features
DIN11 - DIN13 (variables DIN11 - DIN13)
These ve (3) inputs are dedicated as digital inputs only. This group has it’s own common pin, allowing this enre group to be
congured as sinking or sourcing based on the wiring.
As digital input groups DIN6 - DIN10 and DIN11 - DIN13 are separate groups with individual common pins, these two groups can
operate at dierent voltages between 8VDC and 32VDC.
To read a digital input status in a ladder diagram, place and connect the appropriate contact for your needs. The DIRECT
CONTACT and INVERTED CONTACT funcons are used to read digital inputs in the ladder diagram. When placing the
contact, verify you select the correct input address (DIN0 - DIN15) from the provided drop-down menu.
Refer to Figure 2.6 for typical input connecons. Figure 2.6 illustrates the dierent voltages that may be used as well as
sinking and sourcing for digital input groups DIN6-DIN10 and DIN11-DIN13.
Each of the DIN0, DIN1 and DIN2 inputs have soware enabled de-bounce circuitry. This circuitry typically should be enabled when
these inputs are being used as digital inputs. When congured as counter/mer inputs, the de-bounce should typically be disabled.
The de-bounce circuits for each input (DIN0 - DIN2) are enabled and disabled by adding the variables (coils) named
DIN0_DEB, DIN1_DEB and DIN2_DEB respecvely. When the variable (coil) is true, the de-bounce circuit is enabled and
when the coil is false, the de-bounce circuit is disabled. The variables DIN0_DEB, DIN1_DEB and DIN2_DEB are
automacally created by EZ LADDER when the HEC-P6XXX target is selected.
Deleng the de-bounce variables from the program will cause the de-bounce circuit to be enabled. This will reduce the
frequency the input can read, resulng in inputs not operang properly depending upon the applicaon.
Counter Inputs
As was noted in the Digital Inputs Secon, three of the digital inputs (DIN0, DIN1, DIN2) may be ulized as high speed counters.
These counters may be congured in EZ LADDER to operate as an up counters, free running mers and triggered mers. These
inputs will accept a maximum frequency of 100KHz and are opcally isolated to promote noise immunity. These inputs are ideal to
anywhere that high speed counng is required; such as calculang RPM, batch counng and more.
Prior to using the high speed counter / mer inputs in the ladder diagram, the counter / mer funconality must be
installed and congured in the ladder diagram’s Project Sengs.
The rst step to installing the counter / mer funconality is to install the TimerCounter feature. Using menu, click PROJECT then
 to open the Project Sengs window. With the target HEC-P6000 selected sll, click the  buon. The HEC-
P6000 Properes Window will open. Verify the proper actual part number is selected in the Drop-down Part Number select box.
Under the Devices, Internal secon, if the counter / mer were installed, it would be listed.
To install the counter / mer, click the ADD DEVICE buon. From the available devices, select TimerCounter and click OK. Refer to
Figure 2.7.
