Setup IO-channel mode Select first line “PS CoE 0x4000:01… . Enter “0B” for RWH Mode of channel IO-1 Possible selections: “02” = 0FF “03” = IEC 61131 Input “04” = IEC 61131 Output “0B” = RWH ( RFID Read/Write head )

Setup “Data hold time” Select line 2 with “PS CoE 0x4000:02. Enter the request value. Data hold time can be set from 0ms up to 2550 ms. The value set is multiplied by 10 Note: Values set need to be written in hexadecimal values. Example: For 100ms the setting shall be “64” Only necessary for IO-channel mode “Input” and “RWH”

Setup “Transponder data block length” Select line 3 with “PS CoE 0x4000:03” Set “Channel transponder block length” with the values matching to the RFID tag. Only necessary for IO-channel mode “RWH” Note: Values set need to be written in hexadecimal values.
