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 ♦ ProLinx Gateway Functional Overview 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.
