Direct Connection Function Section 1-5

1-5 Direct Connection Function

The communication method applied between the NT11 and the PLC is either a host link or NT link.

The NT11 can be used to refer to the contents necessary for the display information or to allocate the bits and words used for storing the input data to any area in the PLC. The NT11 can directly write and read such allocated bits and words so as to change the display elements, control the operating status, and notify the status.

This function is called the “direct connection function”. The NT11 is designed exclusively for use with the direct connection.

The bits and words allocated by the direct connection function are called “allocated bit” and “allocated word” respectively.

This function allows to read the information to be displayed on the NT11 from the memory area in the PLC and to write it to the memory table in the NT11. Also, the data input on the NT11 can be written to the PLC’s memory area. The NT11 screen status can be switched according to the PLC’s memory area, and the NT11’s status data can be written to the PLC’s memory area.

NT11 PLC

Data memory area Internal relay area

Features of the Direct Connection Function

• The bits and words referring to operating status and work instruction information and those for storing input data can be freely allocated to almost any part of the PLC memory. Bits and words in the PLC can be referenced from any memory table.

• The NT11 can directly refer to PLC bit and word data so that it can be connected to a PLC without changing the PLC program which controls currently running production line.

• The area to control and notify the NT11 status, including display screens, ON/OFF of the backlight, and printing of daily reports and display histories, can be freely allocated to any part of the PLC memory.

The direct connection function allows the NT11 to directly read and write almost all bits and words in the PLC and to automatically change the NT11 screen display. This function can reduce the load on the PLC so that the program development efficiency of the PLC improves.

1-5-1 NT Link

The NT link is a new communication method applied between the NT11 and a PLC.

The NT link uses the direct connection function and can execute high speed communications with a CPU (built-in NT link) of the CQM1, C200HS, and other PLCs.

Auxiliary relay area

Timer/counter

Features of the NT Link • High speed communications with specific types of PLCs can be executed.

• Writing in units of bits to the PLC memory area is possible. (*)

Direct Connection Function Section 1-5

)

• This can be used even when the PLC is in the RUN mode. (*) Except a DM area.

The NT link is compatible with the host link. The NT11 screen data and the PLC programs handled by the host link direct connection can be used with for the NT link as they are.

1-5-2 Functions of the Allocated Bits and Words

Elements displayed on the NT11 and the NT11 status can be allocated to the bits and words of the PLC. By changing the contents of the bits and words, the NT11 can be controlled by the PLC. It is also possible to send data to the PLC by pressing the function keys on the panel of the NT11.

• Controlling the NT11 by a PLC The following NT11 functions can be controlled by a PLC. Screens: Display of designated screens, confirmation of screen

numbers, etc.

Memory tables: Writing to a memory table, copying from a memory table

to another memory table, etc.

System control: ON/OFF of backlight, control of output of daily reports and

display histories at a printer.

• Notifying from the NT11 to a PLC Data in the NT11 is sent to a PLC when a numeric key is pressed. The fol-

lowing types of data are sent to a PLC.

- NT11 status

- Password input status

- Numeric values input by the numeral keys

- Function key input status

Functions of Display Elements

• Numeral memory table Allocation destination: Word

Numeral memory table entry 1 (TIM003)

Connecting to a CVM1/CV-series Host Link Unit

CVM1/CV-series Rack-mounted Unit: CV500-LK201

A CVM1/CV-series Host Link Unit (CV500-LK201) has two connectors (communication ports 1 and 2). Either of these ports can be used for connection to an NT11 by the RS-232C method. However, since the connectors at these ports are of different types, a cable that matches the connector must be prepared.

• Communication port 1 Communication port 1 is a 25-pin connector for RS-232C use only.

• Communication port 2 Communication port 2 is a 9-pin connector that allows selection of the RS-232C or RS-422A method. When this port is used with the RS-232C method, the I/O port selector switch on the front of the Unit must be set to RS-232C (the upper position).

2-5 Connection to a PLC by the Host Link (RS-422A Type)

Connect the NT11 to an OMRON PLC by using the RS-422A type host link method.

If the distance between the NT11 and the PLC is greater than 15 m, this method should be used. The maximum distance over which a connection can be made is 500 m.

when using the RS-422A method, the host computer and PLC are usually connected in a 1 to N ratio (more than one PLC), but in the special case of the connection between the NT11 and PLC, the ratio is 1 to 1.

In order to make a connection to the PLC using the host link method (RS422A type), the “Comm. Type” memory switch of the NT11 must be set to the host link, and the “Comm. Port” memory switch must be set to RS-422A. For details on memory switch settings, refer to 3-7-1 Selecting the Host Commu- nication Method (page 73).

2-5-1 Compatible PLCs

When Using the Host Link Method

Compatible Host Units

Some models and series of OMRON PLCs have the RS-422A type Host Link function built in. With a CS series, CJ series, and CQM1H Board or Unit, and CQM1H, the Host Link method can be used by installing a Serial Communications Board. In addition, some C200HX/HG/HE(-Z)E devices have an integral CPU Unit that can be connected in the Host Link method by installing a Serial Communications Board.

With the CPM2A and CPM2C, an RS-422A type of 1:1 NT Link can be connected through a CPM1-CIF11 RS-422A Adapter.

Check the model and series of the PLC and the type of the installed Board or Unit before making a connection.

In order to transfer the system program from the system transfer tool, first connect the NT11 to a personal computer running the system transfer tool by using the appropriate cable, then proceed as follows.

Reference The NT11 uses one connector for the connection to both a PLC and a com-

puter. If it has been connected to a PLC, disconnect the PLC and connect the system transfer tool (computer) to the NT11, and then, transmit the screen data.

Operation 1. Connect the NT11 to the personal computer running the system transfer

tool, then switch on the power to the NT11.

2. Switch on the power to the personal computer and start up the system transfer tool.

3. When the power to the NT11 is switched ON, the screen shown below is displayed.

Points to observe during transfer of the system program

If any of the following events, or a system error, occurs during transfer of the system program, the program will not be installed in the NT11 correctly.

• The power to the NT11 is switched off, or the NT11 is reset, during transfer.

• The power to the personal computer that is running the system transfer tool is switched off, or the personal computer is reset, during transfer.

• The cable connecting the personal computer running the system transfer tool and the NT11 becomes disconnected or sustains a wire breakage during transfer.

• Transfer is terminated by pressing any two of the function keys on the panel of the NT11.

• Transfer is terminated by pressing the ESC key of the personal computer running the system transfer tool.

In the event of any of the above, there is a possibility that the NT11 will not operate or that unpredictable malfunctions will occur.

To prevent this, switch DIP switch SW2-6 ON to erase the system program after the problem has occurred. For details on erasing the system program with the DIP switch, refer to “Method for Erasing the System Program” (page 68).

Method for Erasing the System Program

In order to erase the system program, the system program area must be cleared. On shipment there is no data in the system program area and therefore the system program can be transferred without having to erase an existing system program first; however, if a system program already exists it must be erased before the new one can be transferred.

The following is the procedure for erasing the system program.

Operation 1. Set DIP SW2-6 to the ON position and turn on the power or reset: the fol-

lowing screen will be displayed.

Precautions to be Observed During the Screen Data Transmission

When any of the following or a system error occurs during the screen data transmission, the transmitted screen data will not be registered correctly to the NT11. If an error message is displayed in the System Menu and the Transmit Mode cannot be selected, the screen data memory needs to be initialized.

• The power to the NT11 is interrupted or the NT11 is reset.

• The power to the computer on which the support tool is running is interrupted or the computer is reset.

• The cable connecting the NT11 to the computer on which the support tool is running is disconnected or has a broken wire.

• Screen data transfer is terminated by pressing any two of the function keys on the panel of the NT11.

• The ESC key on the support tool is pressed to end the transmission.

When the power to the NT11 is turned ON or reset, the screen data is checked. However, if any of the above occurs during the screen data transmission, the screen may disappear and other unexpected problems may occur.

In the case of such problems, set DIP-SW2-2 to ON to initialize the memory. For the memory initialization by using the DIP switch, refer to 3-4-2 Initializa-

tion by Using the DIP Switch (Forced Initialization) (page 65).

3-7 Setting the Conditions of Communications with the PLC

by Using the Memory Switches

The communications between the NT11 and a PLC are called the host communications.

The NT11 can be connected to a PLC by the host link or NT link. The link can be selected by setting the memory switch. Also, the host link baud rate, automatic reset function, etc. are set with the memory switches.

This section describes the communications condition settings by using the memory switches.

Memory Switches The NT11 has the memory areas used to store the PLC connection method,

communications conditions, system settings, etc. which can be used as the switches and called the “memory switches”. Since the memory switches use the flash memory, the stored data can be held even when the power supply is turned OFF.

Setting Functions and the Memory Switch Menu

The memory switches can be set easily by using the memory switch menu in the System Menu.

The following settings can be made with the memory switches. Refer to the subsequent pages for the details of each setting and function.
