INIT

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

Note: There are 2 types of default settings possible:

1. Factory default as described in section 1 (Specifications)

2. Default after INIT as described in section 3 (INIT Default Setup)

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.

Register 40009. When set, Coil 10
can be reset by the controller when

normal communications resumes.

The Power-up Event (Coil 11) is set

be cleared by the controller if desired.

6 Installation / safety

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.

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.
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:

Warning: Electrical
Shock Hazard.

Warning: Consult
user documentation.
