Instructions Manual
１． Overview
1-1. Features● The AL-Ⅱ series is a high speed serial communication system of original controlling the flexible stepping motor,
servo motor which can cope easily as well and I/O in the decentralization of the device and supporting axial addition.
・ The AL-Ⅱ series is an insulation type high-speed serial communications of 20 Mbps/50 m or 10 Mbps/100 m.
As a result, the saving wiring for the personal computer system can be attempted by the performance ( ratio of
our company) that equals a board controller so far.
・ The shift of board controller C-VX870 series ( Device-function) for PCI made of our company and the USB series( Device-function and Unit-function) is easy depending on the device driver function for Windows.
● The status of four axis batch reading and the command of four axis batch execution by the Unit-function became
possible. This Unit-function can perform a unit and AL-Ⅱ interface by one function execution from an application.
By this,・ The time crunch can be done compared with accessed Device-function of each axis and I/O-function ofeach I/O port.
・ The Unit-function ( writing) suppresses the difference at time until it instructs time each axis and each I/O output
signal.
・ The Unit-function can reduce the load of the application.
・ It supports the Device-function, and can use the Device-function.
・ The Unit-function can be used together with the Device-function and the I/O-function.

Error detection of
AL-Ⅱcommunication

・ Reading of error total number
The error total number detected in the AL-Ⅱ communication after the power supply isturned on can be read.
It is possible to use it for the evaluation of the communication environment.
When retrying is detected, it counts as an error.
The error total number can be counted 65535 times or less.
More than it do not update a count.
・ Clear of error total number
The value in which the error total number is counted can be cleared to 0.
・ Retry
It is a function to evade the stagnation of the entire system by retrying it when the influenceof the noise etc. is given to AL-Ⅱ communications.
The number of retrying is set by an Environment-set-function.
When retrying is made effective and the communication abnormality is detected, retrying is
automatically executed.
The setting of retrying is possible by the range from 0 ( non-retry ) to 3.

Initialize

・ Auto transmission of initialization
The master carries out initialization for all slaves automatically when user carries out an
Environment-set-function to a master.
・ Interlock
When an Environment-set-function is executed from the application, master executes
initialization ( a request) to each slave.
The slave product of the AL-Ⅱ series doesn't accept other requests until the initial-request
sent from master is received after the power supply is turned on.
When other requests are received, an initial error is returned.
As a result, master notifies the application the answer back.
When the internal logic on the slave side was reset by the power failure etc. momentarily,
operation by the improper data can be stopped.
Please execute to master an Environment-set-function, after turning on slave's power supply.

4

Backup・ The backup can easily edit the parameter of each slave from USB by initialization editing soft
ware by the OFFLINE, and a master can back up the edited parameter ( Initial data) .
The initial data which a master backs up transmit a message for each slave at the time of thepractice of the Initial-data-transmission-function automatically.

5

ONLINE/OFFLINE
Function・ As for the master board, access are possible from ONLINE ( PCI Express )and OFFLINE ( USB) .
The OFFLINE is a adjustment tool to offer the application that the function used USB toenable machine adjustment without the application program development of the user
immediately for.

* ONLINE and OFFLINE cannot be controlled at the same time.
Execute it after stopping the application from ONLINE when you control from OFFLINE.
* Please refer to each slave unit manual about the specification of the slave unit executed by master.

3-2. Setting of AL-Ⅱ communication
AL2-04/PCIE does the following setting of AL-Ⅱ communications by executing Environment-set-function unlike theswitch setting done with other slave units.

(1) Address setting of the AL-Ⅱ series
The master address is H' 0 fixation.
And, please set not to overlap the address of each slave unit.

(2) Baud rate setting of the AL-Ⅱ series
As for the AL-Ⅱ communication baud rate, 10 Mbps/100 m or 20 Mbps/50 m can be selected.
To transmission rate to set in AL2-04/PCIE, please set the transmission rate of all slave units connected on AL- Ⅱ
communication.

(3) Retry number setting of the AL-Ⅱ series
The setting of retrying is possible by the range from 0 ( non retry ) to 3.
◆ The address of the slave unit, the transmission rate setting become effective at the time of power supply injection.
Please turn on the power supply again without fail.
And to the master execute an Environment-set-function after these setting changes.
Please refer to the device driver manual for Windows for details of function specification.

3-3. Setting of Extend Communication
When the Extend-unit is used, the address setting of the Extend-unit and the hard setting of the baud ratesetting etc. are unnecessary.

● The number of slaves that can be connected directly with the AL-Ⅱ communication are 15 units or less.
Extend I/O that can be extended directly from the slave unit is not included in the number of slaves.

(4) Power supply and slave power supply for communication
The AL-Ⅱ communication power supply of each slave unit is supplied from the AL- Ⅱ master through thecommunications cable so that the entire AL- Ⅱ communication network should not become unstable when the
power supply on each slave unit side is intercepted.
The reconnection of communications can be done by executing Environment-Function to the master when the power
supply of the main unit on the slave side is obstructed.
