1734-485ASC module configuration on EtherNet

[narenperth]

Hi guys,

Have anyone configured 1734-485ASC Module connected to ControlLogix PLC L63 via 1734-AENT Module.
I have a RFID Reader which is wish to connect to PLC using RS485 output from the reader.
Cheers!!!

I've used the 1734-232ASC and 485ASC.

What sort of input and output strings do you need to and from the RFID reader ?

The xxxASC modules work best with ASCII that has delimiters, like CR and LF characters. It's pretty good with fixed-length character sets, and weak with variable-length data that lacks delimiters.

Hi Ken,
My application only needs to read data from RFID Reader.
String BODY is as below
STX ----- DATA ----- ETX
Data Start Sign STX=02H, Data End Sign ETX=03H;
Data is: Antenna Code (1 Byte) + Tag ID (8 Bytes), length is 9 bytes ASCII.

I got following string input
100000000020110602004910 (Reader2600_tag_ID on reader’s software)
01100000000020110602004910 (Hyperterminal_Readout)
$0201100000000020110602004910$03$FF (PLC_Readout on ControlLogix L61 serial port)
I wish to make this work via 1734-485ASC module on a 1734-AENT Chassis.
Not sure is 02 and 03 be start and end delimiters.
Have set the delimiters as 2 and 3 but still doesn’t work. 
