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.
• Transceiver not found (Decimal 1) – Indicates that communications
with the transceiver for the specified channel has been lost.
