Hi everyone.
I badly need help on this one.
I am not able to receive SMS with a GSM modem directly hooked up to an SCU21 v1 of Omron CJ1M PLC.
I have tried RXDU.
I am not quite sure if I am specifying the CORRECT number of bytes to receive.
If this is what I see on hyperterminal if modem is connected to PC:
+CMT: "639354171655",,"13/02/11,11:56:09+32",145,4,0,0,"639170000132",145,4
TEST
Am I right in specifying the bytes to receive to &80?
My control word is F0800000; I use unit0 port1.
I also tried using PDU mode and issued AT+CMGL=4 to list all messages, I keep getting #0205 which corresponds to REQUEST TIMEOUT. I am set to NO PROTOCOL; 8,1,N,9600,1:N.
If you have any idea, please help.
