6. Monitoring function
6.1 Overview
AnyWireASLINK slave units have their own addresses, and when this machine sends out an address, a
response from the slave unit with that address allows for disconnection detection and verifies the existence
of the slave unit.
This machine stores the addresses of the slave units that are connected at the time via the automatic
address recognition operation (described later) into EEPROM. This information is memorized even if the
power is turned off.
Then, the registered addresses are sent out sequentially, and if there is no response, it is displayed by the
machine’s “ALM” LED as a disconnection.
6.2 Automatic address recognition
Storing addresses of the connected slave units onto the EEPROM of this device is called
“Automatic
address recognition.
”
Procedure
1 Check that all of the slave units operate normally.
2
Keep pressing the “SET” switch on this equipment until the “SET” LED (green) lights.
3
After a while, the “SET” LED will turn off. Then, address registration is completed.
Input/output may not be carried out during automatic address recognition. When carrying out the
automatic address recognition operation, stop execution of any PLC programs or execute in a manner
that does not interfere with the operation of the equipment.
The automatic address recognition operation cannot be carried out if there is an error in the
AnyWireASLINK such as a short-circuit, after the power is turned on, or for approximately five seconds
after resetting.
6.3 Monitoring operation
The registered addresses are sent out sequentially, and if there is no response, the
“ALM” LED lights up to
indicate a disconnection.
This error information is retained until the power is turned off or the alarm is reset.
(Refer to the section
“LED display.”)
