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.ssible to know the address of any slave unit that has an error via
the
“INFORMATION” display of this device.
6.2 Automatic address recognition
Storing addresses of the connected slave units into the EEPROM of this machine 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.
Signals may not be inputted or outputted while an address is automatically recognized. To execute
automatic address recognition, perform it in a condition not hampering the operation of the device, for
instance, with the execution of a PLC program suspended.
It is not possible to perform the automatic address recognition if there was an error in the
AnyWireASLINK system, such as a short circuit, and for about five seconds after turning on the power or
a reset operation.
6.3 Monitoring operation
Registered addresses are sequentially sent out, and if there is no response, it is displayed by the machine
’s
“ALM” LED as a disconnection.
This error information is retained until the power supply is turned OFF, or until the alarm is reset.
(Refer to 7. LED display.)
