2 Functional Overview
In This Chapter
Master/Slave Serial Port........................................................................ 11
Module Internal Database .....................................................................11
Protocol Functional Specifications......................................................... 15
The DH-485 protocol driver is designed to accept DH-485 commands from an
attached DH-485 master unit (that is, SLC 5/03 processor ladder logic message
instruction). The DH-485 driver permits a remote master to interact with all data
contained in a module. The data can be derived from other DH-485 devices on
the network through a master port on a module. The driver actively issues DH485 commands to other nodes on the DH-485 network. One hundred userdefined commands are supported by the driver on each port.
2.1 Master/Slave Serial Port
Master mode issues read or write commands to other remote devices on the DH485 network. These commands are user-configured in the module via the master
command list received from the configuration file. Command status is returned to
the processor for each individual command in the command list status data area.
The location of this status block in a module’s internal database is user-defined.
The slave driver mode allows a module to respond to CIF and data read and
write commands issued by a remote node on the DH-485 network.
The Slave driver supports the following DH-485 command set:
Type Access Description
CIF Read 485CIF, Peer-to-Peer, Read MSG requests
CIF Write 485CIF, Peer-to-Peer, Write MSG requests
Data Table Read 500CPU, Peer-to-Peer, Read MSG requests
Data Table Write 500CPU, Peer-to-Peer, Write MSG requests
2.2 Module Internal Database
Central to the functionality of the module is the internal database. This database
is shared between all the ports on the module and is used as a conduit to pass
information from one device on one network to one or more devices on another
network. This permits data from devices on one communication port to be viewed
and controlled by devices on another port. In addition to data from the slave and
master ports, status and error information generated by the module can also be
mapped into the internal database.

DH485 Interface Driver Manual
2.2.1 DH485 Serial Port Driver Access to Database
The module supports the common interface file (CIF) of the DH-485 protocol. A
separate data area can be defined for each application port. This data area is
divided into read and write data and is mapped into the module’s internal
database. The module’s application constantly transfers the read CIF data from
the CIF database to the module database and the write CIF data from the
module to the CIF database. The parameters used to define the CIF database
are contained in the configuration file. This optional feature of the module should
only be utilized if required by a remote master on the network. Otherwise, the
data file functions (500CPU message) instructions should be used to access and
control the module’s data. The following diagram shows the relationship of the
DH-485 drivers, the CIF database and the module’s database:

The Master driver uses the database in two ways:
1 A read command issued to a slave device by the master driver will return the
slave data into the internal database
2 A write command issued to a slave device by the master driver uses the data
in the internal database to write to the slave device. The slave driver
accesses data from the internal database. External DH-485 master devices
can monitor and control data in this database through the slave port. Setup of
the slave port only requires the CFG file.

3.5 [DH485 Port x Commands]
The [DH485 Port x Commands] section for each port defines the commands to
be issued by the module to other devices on the network. These commands can
be used for data collection and/or control.
3.5.1 Command List Overview
In order to interface the DH485 module to act as a master device, you must
construct a command list for each port. The commands in the list specify the
node to be addressed, the function to be performed (read or write), the data area
in the device to interface with and the registers in the internal database to be
associated with the device data. The command list supports up to 100
commands. The command list is processed from top (command #0) to bottom. A
poll interval parameter is associated with each command to specify a minimum
delay time in seconds between the issuance of a command. If the user specifies
a value of 10 for the parameter, the command will be executed no more
frequently than every 10 seconds.
Write commands have a special feature, as they can be set to execute only if the
data in the write command changes. If the register data values in the command
have not changed since the command was last issued, the command will not be
executed. If the data in the command has changed since the command was last
issued, the command will be executed. Use of this feature can lighten the load on
the network. In order to implement this feature; set the enable code for the
command to a value of 2.

the following codes:
0 = Read
1 = Write
3.5.10 File Type
This field defines the file type to be interfaced with in the other DH-485 node. The
program utilizes the following codes for this field:
0 = Status File (2 bytes per element)
1 = Bit File (2 bytes per element)
2 = Timer File (6 bytes per element)
3 = Counter File (6 bytes per element)
4 = Control File (6 bytes per element)
5 = Integer File (2 bytes per element)
6 = Floating-point File (4 bytes per element)
10 = CIF File (1 byte per element)

the shield, and when used in the configuration shown, it must be wired externally.
Verify that the RS interface jumper on the module is set to the correct position:
RS-232 or RS-485.
Note: Terminating resistors are generally not required on the RS-485 network, unless you are
experiencing communication problems that can be attributed to signal echoes or reflections. In this
case, install a 120 ohm terminating resistor on the RS-485 line.

license agreement accompanying such software); transfer software to a
third party separately from the Product; modify, alter, translate, decode,

license agreement accompanying such software or other intellectual
property. Failure to do so may void this Warranty with respect to such
