[ c ] MECHATROLINK Definition Settings
■ Transmission Parameters Tab Page
This tab sets the parameters required to use the MECHATROLINK communication system.
* 1.
* 2.
It is recommended to set the communication cycle to an integral fraction (1/n, where n is an integer)
of the high-speed of the CPU Module. Always set the same communication cycle when performing
interpolation between different SVB-01 Modules.
1 Number of retry to slaves
Communication will be retried for slave stations from which a normal response is not received. This
setting specifies the maximum number of stations for which communication is to be retried in one
transmission cycle.
Setting Details
Communication Type
Sets the communication type, from among MECHATROLINK-I,
MECHATROLINK-II (32 Byte Mode), and MECHATROLINK-II (17 Byte
Mode).
Master/Slave
Sets whether the SVB-01 Module is used as a Master station or a Slave station.
Make sure that the setting matches the SVB-01 Module’s DIP switch setting.
My Station Address
(Local Station Address)
When the Machine Controller is being used as a master station, the local station
address is fixed at 0 and cannot be changed. When it is being used as a slave
station, set a station address between 1 and 30.
The upper limit value for the station address depends on the master
specifications.
Transmission Speed *1
Displays the transmission speed for communication. The Transmission Speed
varies depending on the Communication Type.
Transmission Byte
(Transfer Byte)
Sets the number of transfer bytes.
Communication Cycle *2
Sets the communication cycle. Select either 0.5, 1, 1.5, or 2.0 ms. The
Communication Cycle varies depending on the Communication Type.
Message Confidence
Level
Sets the error recovery level for sending MEMOBUS commands.
Set only for MECHATROLINK-I.
0
Send command just once and wait indefinitely for a response from the
destination.
1
Send command once and resend if a response is not received within 8
seconds.
2
When sending the command, send each word of data twice
consecutively and wait indefinitely for a response from the destination.
This method improves transmission quality but reduces transmission
efficiency by 50%.
SigmaWin Sets whether or not to use SigmaWin. Set only for MECHATROLINK-II.
Number of retry to
slaves
1
Sets the number of retries to slaves. Set only for MECHATROLINK-II.
Number of slaves
Displays the maximum number of slaves depending on the Communication Type,
Communication Cycle, SigmaWin, and Number of retry to slaves.
*3
Communication Type Transmission Speed
MECHATROLINK-I Fixed at 4 Mbps.
MECHATROLINK-II (17 Byte Mode) Fixed at 10 Mbps.
MECHATROLINK-II (32 Byte Mode) Fixed at 10 Mbps.
Communication Type Communication Cycle
MECHATROLINK-I Fixed at 2 ms.
MECHATROLINK-II (17 Byte Mode) Select either 0.5 or 1 ms.
MECHATROLINK-II (32 Byte Mode) Select either 0.5, 1, 1.5, or 2.0 ms.
