In This Chapter

 Master/Slave Serial Port(s) .................................................................... 10

 Module Internal Database ..................................................................... 11

The DF1 Master/Slave Protocol driver can exist in a single port (DFCM) or a
multiple port (DFCM4) implementation. In either case, the driver can be
configured on an individual port basis to operate as either a DF1 Master or a
Slave. Each port is independently configured for communication on a DF1
network and interfaces with the internal database in the module.

Functional Overview DFCM ♦ ProLinx Gateway
Driver Manual DF1 Master/Slave

1.1 Master/Slave Serial Port(s)

The ProLinx module supports the DF1 protocol as a Master or Slave on up to
four ports. Each of the ports is individually configurable.

The relationship between the port labeling on the front of the ProLinx module and
the application is as follows:

Port Label Function

Debug Debug/Configuration
Port 0 DF1 Port 0

Following ports only exist on multiple port units

Port 1 DF1 Port 1
Port 2 DF1 Port 2
Port 3 DF1 Port 3

One or more DF1 protocol master ports can be configured on the module to
continuously interface with DF1 slave devices over a serial communication
interface (RS-232, RS-422 or RS-485). Each port is configured independently.
Support for half-duplex (master-slave) and full-duplex (point-to-point) DF1 links
are provided on the ports. User defined commands determine the commands to
be issued on each port. Up to 100 commands can be defined for each port. Data
read from the devices are placed in the virtual database. Any write requests for
the DF1 slave devices are sourced with data from the virtual database.

The module can be configured to place slave devices that are not responding to
commands from the master ports at a lower priority. If the module recognizes that
a slave device has failed to respond to a message after the user defined retry
count, it will mark the slave as "in communication failure" and set the error delay
counter to the specified value. Each time the module encounters this slave in the
command list, the counter will be decremented. When the value reaches zero,
the slave will be placed in an active status. This facility can improve
communication throughput on the network.

If the DF1 master port is configured to support the DF1 half-duplex protocol, the
master port can be used to route messages between slaves. Peer-to-peer
communication is accomplished by the master constantly polling all the slaves on
the network and relaying the messages received. The slaves must contain ladder
logic with MSG commands to generate and accept messages. This routing can
be used in conjunction with the normal command processing discussed above.

DF1 slave devices can be emulated on the module to interface with remote DF1
master devices. Each port is configured independently. Support for half-duplex
(master-slave) and full-duplex (point-to-point) DF1 links are provided on the
ports. Simulation of a selected set of functions from the basic, PLC5 and SLC
command sets are supported. Virtual files are mapped to the internal database in
the module to provide support of the PLC5 and SLC command sets.

DF1 Master/Slave Driver Manual

1.2 Module Internal Database

The internal database is central to the functionality of the module. 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.

1.2.1 DF1 Serial Port Driver Access to Database

The following diagram describes the flow of data between the serial port drivers
and the internal 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 DF1 master
devices can monitor and control data in this database through these slave
port(s). Setup of the slave ports only requires the CFG file.

This section discusses several characteristics in the module’s configuration and
operation that are unique to the emulated DF1 slave ports. In order to support
several types of DF1 devices, the slave ports require additional configuration
parameters. If the basic command set is used, these features need not be
considered. These features must be considered if the module has the potential of
receiving a PLC5 or SLC command function.

DFCM Slave Driver Operation DFCM ♦ ProLinx Gateway
Driver Manual DF1 Master/Slave

3.1 File Simulation

The PLC5 and SLC command sets require the use of data files. These entities
are simulated in the module and are configured by the user. Data in these
processors are stored in files such as N10:, F20: and A25:. Each file has a
defined element size and length. The module simulates these files by assigning
each element to a word-size (two bytes) register in the module’s database, and
each file is set to a fixed, user-defined length. These files are mapped to the
database under user control. A discussion of each parameter related to the file
simulation is given below along with an example.

[SECTION]/Item Range Description

[DF1 PORT 0]
[DF1 PORT 1]
[DF1 PORT 2]
[DF1 PORT 3]

First File: This parameter defines the first file number recognized by

File Size: This parameter defines a constant size for all files

File Offset:

the module. If the value is set to 7, all requests for files
less than 7 will be returned as an error message. Files
greater than or equal to 7 will be processed as long as
the elements referenced are valid for the database. If a
request is received for an element beyond the last
register in the database, the module will return an error
message.

simulated by the module. If the parameter is set to 100,
all files will contain 100 elements. If the First File
parameter is set to 7 and the File Size parameter is set to
100, all files (N7:, N8:, N9...) will contain 100 elements.

This parameter defines the starting address in the

module’s internal database to be associated with the first
element in the first file to be simulated. For example, if the
First File parameter is set to 7 and the File Offset
parameter is set to 1000, file element N7:0 will
correspond to database register 1000 and N7:100 will
correspond to register 1100.

4 Communication Port Cables

This section contains information on the cable and pin assignments for the
ProLinx module's serial ports (RS-232/422/485). The ProLinx module will come
with one to five serial ports, depending on the configuration purchased. In all
cases, the protocol serial ports will have the same pinouts.

Example: The 5202-MNET-MCM4 module contains five serial communication ports; four
configurable protocol application ports and one Configuration/ Debug port.
The 5201-MNET-MCM module contains two serial communication ports; one configurable protocol
application port and one Configuration/Debug port.

Each physical serial port has an eight-pin Mini-DIN jack connector. A six-inch
Mini-DIN-8Male to DB-9Male adapter cable is provided for each serial port. The
DB-9M provides connections for RS-232, wired as Data Terminal Equipment
(DTE), RS-422 and RS-485. The diagrams in the following topics detail the pin
assignments for several possible electrical interface connections.

4.1.2 Port 0, 1, 2, 3: RS-232 - Null Modem (DTE without Hardware

Handshaking)

This type of connection can be used to connect the module to a computer or field
device communication port.

Note: If the port is configured with the Use CTS (page 34) set to YES, then a jumper is required
between the RTS and the CTS line on the module connection.

4.1.3 Port 0, 1, 2, 3: RS-232 - DTE to DCE Modem Connection

This type of connection is required between the module and a modem or other
communication device.

The Use CTS Line (page 34) parameter for the port configuration should be set
to YES for most modem applications.

4.1.4 Port 0, 1, 2, 3: RS-422 Interface Connections

The following illustration applies when the RS-422 interface is selected.

4.1.5 Port 0, 1, 2, 3: RS-485 Interface Connections

The following illustration applies when the RS-485 interface is selected.

NOTE: This type of connection is commonly called a RS-485 half-duplex, 2-wire connection. If you
have RS-485 4-wire, full-duplex devices, they can be connected to the module's serial ports by
wiring together the TxD+ and RxD+ from the two pins of the full-duplex device to Pin 1 on the
module and wiring together the TxD- and RxD- from the two pins of the full-duplex device to Pin 8
on the module. As an alternative, you could try setting the module to use the RS-422 interface and
connect the full-duplex device according to the RS-422 wiring diagram (page 24). For additional
assistance, please contact ProSoft Technical Support.

5.2 LEDs for Serial DF1 Protocol Ports

Troubleshooting the operation of the serial DF1 protocol ports can be performed
using several methods.

The first and quickest is to scan the LEDs on the module to determine the
existence and possibly the cause of a problem. This section provides insight into
the operation of the Serial Port status LEDs.

Some ProLinx modules will include three extra serial ports. Each of these serial
ports has two LEDs indicating status.

LED Color Description

Port 0 - ACT
Port 1 - ACT
Port 2 - ACT
Port 3 - ACT

Port 0 - ERR
Port 1 - ERR
Port 2 - ERR
Port 3 - ERR

Off No activity on the port.

Amber
On or Flashing

The port is either actively transmitting or

indicating activity, there are no communication
errors

Activity on this led indicates some
communication error was detected, either during
transmit or receive. To determine the exact error,
connect the Debug terminal to the Debug port.

Note that the meaning of the other LEDs on the unit can be found in the Product
Manual for the specific module that is being debugged.
