CAUTION

• Before starting installation or wiring work, be sure to shut off all phases of external power supply used by the system. Failure to shut off all phases could lead to electric shocks, product damage or malfunctioning.

• Always install the terminal covers enclosed with the product before turning ON the power or operating the product after installation or wiring work. Failure to install the terminal cover could lead to electric shocks.

• Before cleaning or tightening the terminal screws, be sure to shut off all phases of external power supply used by the system. Failure to shut off all phases could lead to module trouble or malfunctioning. A loose screw could lead to dropping, shortcircuiting or malfunctioning. If the screw is too tight, dropping or short-circuiting malfunctioning could occur due to screw damage.

• Do not bind the control wire or communication cable with the main circuit or power wire, or place the control wire near these. Separate by at least 100mm or more. Failure to observe this could lead to malfunctions caused by noise.

• Always ground the FG terminal with Class D grounding (grounding resistance : 100

or less) or higher dedicated of the programmable controller.

Failure to do so could lead to electric shock or malfunctioning.

• Always confirm the product's rated voltage and terminal layout before wiring the module. Connecting with a power supply other than the rated power supply, or incorrect wiring could lead to fires or trouble.

• Securely mount the connector of each connection cable to the mounting section. An incomplete connection could lead to malfunctioning causes.

• Be sure to fix the wires or cables by ducts or clamps when connecting them to the module. Failure to do so may cause damage of the module or the cables due to accidental pull or unintentional shifting of the cables, or malfunctions due to poor contact of the cable.

• Do not install the control lines together with the communication cables, or bring them close to each other. Failure to do so may cause malfunctions due to noise.

• Always connect the master module and CC-Link dedicated cable at the data link terminal block. If the data link terminal block and general-purpose output terminal block are incorrectly inserted, module trouble could occur.

5.6 Reading and writing the buffer memory (using the buffer memory automatic update function)

The methods for reading and writing the R2 buffer memory using the buffer memory automatic update function is described in this section. When the buffer memory automatic update function is used, data can be read and written using the FROM/TO command, so the sequence program can be simplified.

5.6.1 Outline

With the buffer memory automatic update function, if a cause of data communication between the R2 buffer memory automatic update area and master station automatic update buffer is generated, the data is automatically exchanged, and the data in the corresponding area of each station is updated. Refer to section 5.6.2 for details on each area and the update timing.

•

Reading : The master station buffer memory corresponding to the buffer memory

to be read is read out with the FROM/RIFR command.

•

Writing : Data is written to the master station buffer memory corresponding to

the buffer memory to be written in using the TO/RITO command.

If a cause of automatic update, explained in section 5.6.2, occurs, the area is automatically updated.

(1) Changing the bank when using the A Series master module

When using the A Series master module (AJ61BT11/A1SJ61BT11), the master station's automatic update buffer will be "bank 2". Thus, create the program so that the bank is changed to "bank 2" when reading to or writing from the automatic update buffer, and so that "bank 0" is returned to after the reading/writing is completed. When using the RITO/RIFR commands dedicated for the AnSHCPU, the bank will not be changed automatically by the commands. Thus, the bank must be changed by the user. Refer to section 5.2 for details on changing the bank.

(2) Setting the timeout

By setting the following buffer memory in the R2, a timeout can be set for exchanging data between the R2 and master station when using the buffer memory automatic update function.

5.7 Reading and writing the buffer memory (using the transmission/reception buffer)

The method for reading and writing the R2 buffer memory using the transmission/reception buffer is described below. When the transmission/reception buffer is used, the required size only can be adequately transmitted so excess data is not transmitted. This allows the transmission path efficiency to be improved.

5.7.1 Outline

When reading and writing the R2 buffer memory using the transmission/reception buffer, reading and writing are carried out using the intelligent device station access request signal (RY(n+1)E) and the intelligent device station access complete signal (RX(n+1)E). The master station buffer memory uses the transmission/reception buffer.

When the dedicated commands RIWT/RIRD/RISEND/RIRCV are used, the intelligent device station access request signal (RY(n+1)E) and intelligent device station access complete signal (RX(n+1)E) are controlled by the dedicated commands, so the user does not need to establish an interlock.

5 PRELIMINARY INFORMATION

(1) Changing the bank when using the A Series master module

When using the A series master module (AJ61BT11/A1SJ61BT11), the master station's automatic transmission/reception buffer will be "bank 1". Thus, create a program that changes to "bank 1"when reading or writing to the transmission/reception buffer, and returns to "bank 0" when the reading/writing is completed. When using the dedicated commands RIWT/RIRD/RISEND/RIRCV, the bank will be changed automatically by the dedicated commands, so the user does not need to change the bank. Refer to section 5.2 for details on changing the bank.

5.7.2 Control data

When transmitting data using the transmission/reception buffer, the control data must be added to the transmission data before transmitting. When receiving data, the control data will be added to the head of the reception data. The following examples are explained in this section for the control data.
