4 FUNCTION

4.1 Function List
Description
Exchanges I/O data of up to 384 points (input max. 256 points, output max. 256 points)
between the FX5-ASL-M and a slave module.
A double check is an error control system. In this system, cycle data in AnyWireASLINK
transmission is recognized as valid data if the data matches with the data of the last
transmission or is ignored as invalid data if the data does not match with the last data.
A double check ensures reliability of communication.
In AnyWireASLINK, parameter information of a slave module and the AnyWireASLINK system
in addition to I/O information are sent and received between the FX5-ASL-M and a slave
module.
Execute this function to check or change parameter information of a slave module.
Description
Enables the FX5-ASL-M to detect and store the ID (address) of the connected slave module
when the SET switch on the FX5-ASL-M is pressed.
Changes an ID (address) of a slave module using the buffer memory area without an address
writer.
Checks whether the same ID is used for multiple slave modules through automatic address
detection or same address used check. The LEDs of the relevant slave modules are forcibly
turned on.
Detects slave modules with no ID assigned (default ID) through automatic address detection
or same address used check.
Description
Protects the system by detecting the current out of the specifications of the AnyWireASLINK
system across DP-DN or 24V-DP and stopping the transmission.
Notifies the ID of a slave module that has been separated from the FX5-ASL-M because of
disconnection in the transmission cables (DP, DN) between the FX5-ASL-M and the slave
module, to locate the disconnection in the transmission cables (DP, DN) from the upper
system.
Detects a voltage drop in the 24 V DC external power supply, enabling the FX5-ASL-M to
detect a failure in the 24 V DC external power supply or a wiring error from the upper system.
Description
Allows parameter access errors to be detected.
Allows for automatic error reset for DP/DN disconnection errors and parameter errors after the
error status is cleared.
Allows for automatic acquisition of information of slave modules when the CPU module is
reset or power off and on the system.
