1Functional Overview

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

1.1Master/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

1.2Module 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:

1A read command issued to a slave device by the master driver will return the slave data into the internal database

2A 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.

In This Chapter
	File Simulation.......................................................................................	18
Example Slave Port Application ............................................................		19
	Slave Port Command Support...............................................................	20

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

3.1File 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]		Configuration Header for Port 0
[DF1 PORT 1]		Configuration Header for Port 1
[DF1 PORT 2]		Configuration Header for Port 2
[DF1 PORT 3]		Configuration Header for Port 3
First File:		This parameter defines the first file number recognized by
		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.

File Size:

File Offset:

This parameter defines a constant size for all files 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.

DF1 Master/Slave	Driver Manual

4Communication 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.

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 TxDand RxDfrom 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.

LED indicators provide a means of monitoring the operation of the unit and individual ports and are extremely useful for troubleshooting. In addition to port monitoring, system configuration errors, application errors, and fault indications are all monitored with LEDs providing alerts to possible problems. The ProLinx Reference Guide provides more information on LEDs and troubleshooting.

5.1Base Module LEDs

LED	State	Description
Power	Off	Power is not connected to the power terminals or source is insufficient
		to properly power the module (minimum required is 800mA at 24 Vdc)
	Green Solid	Power is connected to the power terminals.
Fault	Off	Normal operation.
	Red Solid	A critical error has occurred. Program executable has failed or has
		been user-terminated and is no longer running. Press Reset p/b or
		cycle power to clear error. If not, use the Debug procedures described
		later in this manual.
Cfg	Off	Normal operation.
	Amber Solid	The unit is in configuration mode. The configuration file is currently
		being downloaded or, after power-up, is being read, the unit is
		implementing the configuration values, and initializing the hardware.
		This will occur during power cycle, or after pressing the reset button. It
		also occurs after a cold/warm boot command is received.
Err	Off	Normal operation.
	Flashing	An error condition has been detected and is occurring on one of the
		application ports. Check configuration and troubleshoot for
		communication errors.
	Solid Red	This error flag is cleared at the start of each command attempt
		(Master/Client) or on each receipt of data (slave/adapter/server); so, if
		this condition exists, it indicates a large number of errors are occurring
		in the application (due to bad configuration) or on one or more ports
		(network communication failures).

5.2LEDs 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	Off	No activity on the port.
Port 1 - ACT
	Green	The port is either actively transmitting or
Port 2 - ACT	Flash	receiving data
Port 3 - ACT

Port 0 - ERR

Port 1 - ERR

Port 2 - ERR

Port 3 - ERR

Off	Normal state. When off and Port Active led is
	indicating activity, there are no communication
	errors
Amber	Activity on this led indicates some
On or Flashing	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.
