Error Codes for RFID Interface Block

Error Codes

The error codes for the RFID interface block are stored in the input for each

channel. In the examples in the manual, the error codes are stored in the image

table RFID_1:I:Channel[0].ChError and RFID_1:I:Channel[1].ChError.

• OK (Decimal 0) – Indicates there are no issues with the channel in

question when the decimal value of these bits is equal to zero.

• Tr a ns c e i v e r n o t f o un d ( De ci m a l 1 ) – Indicates that communications

with the transceiver for the specified channel has been lost.

• Invalid Response (Decimal 2)– Indicates that the response to a command

is not what was expected.

• Invalid Parameter (Decimal 3) – Indicates that either a parameter passed

or received was out of bounds.

• No Tag Detected (Decimal 4)– Indicates that a command was attempted

on a channel but there was no tag detected in the field.

• Instruction Timed Out (Decimal 5)- Indicates that the timeout value

associated with a command was exceeded before a response could be

obtained.

• Block Access Error (Decimal 6) – Indicates that either:

– A read command attempted to read a block but was denied access.
