3 Init Default Setup
Communication parameters will be set to INIT default after performing the procedure:
1. Install jumper between INIT and GND terminals of the RS-485 port.
2. Apply power to Smartmod unit.
3. Read parameter words to see current parameters.
4. Write changes if necessary.
The INIT Default RS485 Settings Are:
Modbus ID = 1
Baud rate = 9600
Parity = None
Stop Bits = 1
Data Bits = 8
No handshake
4 Configuration DATA
SmartMod Configuration settings are mapped into Modbus Register space. This
configuration data may be modified with any Modbus/RTU Master device. For
convenience, Horner APG has developed a variety of Cscape application files which
allow an OCS (Xle, NX, LX, QX) to act as a SmartMod configurator. Initial
configuration of SmartMod module should be done on an individual basis, since all
modules come from the factory with a default Modbus ID of 1. Once each module on
the network has its own unique Modbus ID, further configuration adjustments can be
made with the entire network powered.
All configuration parameters listed below (except 40012 Channel Enable) are stored
in EPROM. That means they should not be constantly rewritten.

5 Input/Output DATA
SmartMod Analog I/O utilizes both Modbus Registers (40001-40030) and Coils (1-11). It is
possible to access all data using Registers only, because the Coils can be accessed through
Register 40010.
The following tables lists all Modbus I/O data available.

00010 Watchdog Event Read/Write
00011 Power-up Event Read/Write
If Coil 9 (Watchdog Enabled)
is set, Coil 10 (Watchdog
Event) will set if the Watchdog
Timeout value is exceeded.
The Watchdog Timeout value
is set in Register 40009.
When set, Coil 10 can be
reset by the controller when
normal communications
resumes.
The Power-up Event (Coil 11)
is set every time the power is
applied. It can be cleared by
the controller if desired.
6 Installation / safety
a. All applicable codes and standards should be followed in the installation of this product.
b. Shielded, twisted-pair wiring should be used for best performance.
c. Shields may be terminated at the module terminal strip.
Warning: Remove power from the OCS controller, CAN port, and any peripheral
equipment connected to this local system before adding or replacing this or any
module.
d. In severe applications, shields should be tied directly to the ground block within the panel.
e. Use the following wire type or equivalent: Belden 8441.
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.
When found on the product, the following symbols specify:
