RSLogix 5000 Controller Tags

• Reset

– The channel reset bit is used to command an RFID channel reset.

A value of 0 indicates the channel is not being commanded to reset, a value
of 1 indicates a request to reset the channel.

• Timeout

– This value determines how long the interface will wait for a

command response from the transceiver before indicating a message time
out. The default value is 0, which sets the timeout at 750 ms. The user can
enter a timeout value in milliseconds, keeping in mind that a low timeout
value can cause command failures by timing out before the command
would otherwise have successfully completed.

• UIDHi

– The channel UID word is an 8-byte value that will contain the

UUID information for specific commands that will allow the command to
be targeted to a specific tag in the field. Under normal circumstances this
value will be 0, which tells the RFID interface to perform an action
regardless of what tag it is. Any value other than 0 will attempt to direct the
command to that specific tag. The UIDHi value contains bytes 0…1 and
6…7 of the UID.

• UIDLow

– The UIDLow value contains bytes 2-5 of the UID.
